Xcode error "Could not find Developer Disk Image"

Question

When attempting to run a build on a connected iOS device in Xcode I get the error:

Could not find Developer Disk Image

I saw that there was a public beta for Xcode, so I installed it.

One of the new features is that you don't need to have a Developer Program Account Dingus to upload your app directly to your iPhone.

However, on my iPhone 4s, I also did a public beta update to iOS 8.4, problem being, that there's no Developer Disk Image available for it.

Where do I to find it or how can it be fixed?

Update your XCode – Arteritis

For people getting this when deploying to Apple TV... update to Xcode 7.3 Beta 2 and install tvOS 9.2. – Calf

It is shown also when using an updated device to run on, but you did not update your xcode version. A newer iOS Version that your xcode doesn't know. As said before, just update your xcode. – Assertive

Sometimes its not as easy as updating your version of Xcode! Updating your version of Xcode means your are compiling with a newer version of the SDK but you still might want support for earlier versions. I should be able to use an older version of Xcode and run on a device with a newer version of the OS. This is ridiculous. Sounds like Apple is trying to force people to lose support for older versions of the OS. – Derekderelict

You will get this error when Xcode doesn't support that iOS version. Check iOS version and accordingly install XCode (Both should be latest) – Maui

Ah good, I can only upgrade Xcode, if I upgrade my OS X first. And there goes my entire afternoon, downloading and installing several gigs of files... all because I stupidly updated my iPhone (to stop it nagging me every bloody day). Oh, and I can't update my company's MacBook OS as our Symantec anti-virus doesn't support Sierra yet. So I can't work with my updated iPhone at all with Xcode. I haaaaaate Apple. – Ribosome

Did not touch the mac since 1/2 year. Now just tried to start my app for a little 3 second check from XCode. "Could not find Developer Disk Image". Now a lot of hours work will start , trying to update xcode and OS and and and and.... I hate Apple like speaker before. Will cancel development on Apple and concentrate on Android and Windows. – Janson

This is not a question about programming. This looks like a bug from the IDE, I would suggest filling a bug request to Apple here: bugreport.apple.com – Complemental

Answer 1

I am facing the same issue on Xcode 7.3 or Older version of your Xcode and my device version is iOS 10 or newer version of your OS.

This error is shown when your Xcode is old and the related device you are using is updated to latest version.

We can solve this issue by following the below steps:

Method 1:-

• Right click on Xcode 7.3 or version of your Xcode, now select "Show Package Contents", "Contents", "Developer", "Platforms","iPhoneOS.Platform", "Device Support".

• Now check there is latest version of developer disk image(folder) like 12.1 or newest version(folder) in your case. Copy the latest version and Paste in the same Folder Device Support.

• In my case I have 12.1 is the latest folder. Now it will generate the copy of that version like 12.1 copy or newest version(folder)copy in your case.

• Now Change the name of copy folder to your latest version of iPhone like. In mine case, I have 12.1(Folder)copy and rename it into 12.4. As you can see in the above screenshot. You can change it according to your latest version of phone. I need it for 12.4 so i just rename the folder to 12.4.

• Now your Xcode has a new developer disk image. Close the finder now, and quit your Xcode. Open your Xcode and the error will be gone. Now you can connect your latest device to old Xcode versions.

                        **OR**
  

Method 2:-

First of all, download the latest Xcode Version. No Need to install the latest Xcode.

We can solve this issue by following the below steps:

• Right click on Xcode 8 or Newer version of your Xcode, select "Show Package Contents", "Contents", "Developer", "Platforms", "iPhoneOS.Platform", "Device Support"
• Copy the 10.0 folder (or above for later version).
• Back in Finder select Applications again
• Right click on Xcode 7.3 or version of your Xcode, now select "Show Package Contents", "Contents", "Developer", "Platforms", "iPhoneOS.Platform", "Device Support"
• Paste the 10.0 folder (or above for later version).

Now your Xcode has a new developer disk image. Close the finder now, and quit your Xcode. Open your Xcode and the error will be gone. Now you can connect your latest device to old Xcode versions.

OR

If you can't download the latest Xcode, you can get the latest Developer Disk Image for your Xcode from this link:-

Thanks to Yatko. So that people can download the latest DMGs.

Answer 2

For people who would have similar problems in the future, beware that this problem is fundamentally rooted in the mismatch of your iOS version and Xcode version.

Check the compatibility of iOS and Xcode.

Gimbals

"Check the compatibility of iOS and xcode." How? I just ran recommended system updates on both my Mac and iOS device and still getting this issue. iMac is 10.11.4, iOS is 9.3.1, Xcode is 7.2 how do I know what is out of sync with what? – Barra

Xcode 7.3 includes SDKs for iOS 9.3 developer.apple.com/library/mac/releasenotes/DeveloperTools/… – Gimbals

The error message is really terrible. "iOS version mismatch, If problem persists, try updating XCode" would be so much more useful. – Decurrent

I'm having this issue using latest iOS (9.3.2 (13F69)) and latest OS X (10.11.5 (15F34)) + Xcode (Version 7.1 (7B91b)). No updates available. – Fibrilliform

Ok, I see now there is Xcode 7.3 (other people have it). Strangely, App Store app didn't notify me about any updates to Xcode being available (as it usually does). So Xcode indeed wasn't the latest. – Fibrilliform

But what does one do when there is no matching Xcode version for the current iOS? For example, at the time of writing the latest version of Xcode is 15.0.1 and ships with iOS 17.0 SDKs. But the latest version of iOS is 17.1.1. And the answer here isn't “Xcode beta”, because the current beta is Xcode 15.1 beta 2 which ships with iOS 17.2 beta SDK. – Fogbow

Answer 3

I personally downloaded Xcode 6.4 beta and 7.0 beta and I was very happy to find the solution by searching "8.4" inside the application folder of the 6.4 beta. By doing this, I found the folder 8.4 (12H4125a) containing the iOS 8.4 image and I copied this folder to the same path of the 7.0 beta. The path is the following:

/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport 

When you will reopen Xcode 7 and choose your device, there will be an error message; just click on fix issue and that should do it!

Curia

I am not sure which folder you are talking about, but you only have to copy this folder: "8.4 (12H4125a)" (or whatever firmware image you need), which is located in this path: "/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport". – Curia

Thanks @NicolaD.! Also, an alternative to copying the image is to symbolically link to it: ln -s /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/8.4\ \(12H141\) /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport. – Everyday

Another note: You must run the Xcode beta at least once and let it complete the "verifying" step before copying the 8.4 folder, or it will report that it is damaged. – Selfcontrol

Could someone please upload 8.4 disk image somewhere so there is no need to download full Xcode 8.4 package. It must be around 13MB. – Beare

Since the Xcode 6.4 is no longer in beta, I wanted to comment and confirm that this process does work identically for this new production version. – Manysided

I'm seeing the same issue with Xcode 7.2 beta (7C46I) released today - this does not have the Developer Disk Image for iOS 9.1. I had to copy the directory for "9.1 (13B137)" from the Xcode.app/.../Device Support folder over to the Xcode-beta.app/.../Device Support folder in order to run apps on my iOS 9.1 devices via the Xcode 7.2 beta.. – Pibgorn

@DerekLee: 7.2 beta release notes state 'Devices • Build and Run on devices running iOS 9.1 is not supported in Xcode 7.2 beta. (23224972)' - Don't you think there's a gotcha with this approach? -> There is no disk image available for the 7.1 release, only a direct update in the store. Could you please send me the 9.1 folder to give it a try. Downloaded 7.1 release 3 times but my mini refuses to install it... - So I have no access to '9.1 (13B137)' for copying it to my 7.2 beta. – Outdoor

@mramosch: Nice find - I should have checked the release notes. You should be able to run both the GM version of Xcode 7.1 (installable either via download or the App Store) as well as the beta together on the same machine. Not being able to install to a 9.1 device from Xcode 7.2 was really just an inconvenience for me since you can install to a 9.1 device from Xcode 7.1 GM. Sounds like you'd be best to troubleshoot the installation. Sorry I can't be of more assistance. – Pibgorn

@DerekLee: Finally got 7.1 to install on my mini and managed to copy the missing 9.1 folder from 7.1 into the 7.2 beta packet so that it runs my 9.1 devices without complaint now. But I don't know if they work without any side effects as the release notes state 'Build and Run on devices running iOS 9.1 is not supported in Xcode 7.2 beta' – Outdoor

@Outdoor - As I mentioned above, I would recommend testing your 9.1 devices using Xcode GM 7.1, and only use the beta for testing against the beta (iOS9.2). Being able to install to a 9.1 device from Xcode 7.2 beta is really just a convenience. – Pibgorn

My situation is Xcode 7.2 and MacOS 10.10.5 (Yosemite). I downloaded the Xcode 8 Beta (developer.apple.com/download) and copied: ~/Downloads/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/9.3 to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/ . This put the DeveloperDiskImage.img in the right place. Then restarted Xcode 7.2 and suddenly (after clicking "fix errors") it was able to install and debug to my 9.3 device. – Bull

Worked well for me with iOS 10 / Xcode 8 beta 2: sudo cp -r /Applications/Xcode8-beta2.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.0\ (14A5297c)/ /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/ – Supereminent

Answer 4

This error occurs when the version of Xcode predates that of the device.

For example, attempting to run a build on a device running iOS 9.3 in Xcode 7.2 results in this error; Could not find Developer Disk Image.

Why an error message that actually describes what the hell is going on can't be provided is beyond me (Apple, I'm looking at you 👀).

Update to the latest version of Xcode through the App Store or via direct download to guarantee interoperability with connected iOS hardware.

Sulfapyridine

checked and there's no updates for xcode, but the error is there. then i searched for it, it goes 'update' on me. oh apple, why you do this to me? downloading now, hope it works. – Orlosky

@Orlosky The AppStore app is total garbage, anyone else having similar problems there's a debug menu you can activate – Sulfapyridine

i did a direct download as it seemed a better/faster option. then i cant run the latest xcode (7.3) because my osx is 'old' (10.10) and it requires the latest. note to self: update everything or nothing. still not happy, apple. – Orlosky

See my comment above. I was able to just steal the 9.3 folder out of the Xcode 8 Beta download, and place it in Xcode 7.2. This works, at least for now. It just can save you having to upgrade to El Capitan and Xcode 7.3.1 until you're ready to do so. – Bull

Answer 5

If you're using old Xcode and want to run onto devices with new version of iOS, then do this trick. This basically make a symbolic link from iOS Device Support in new Xcode to old Xcode

https://gist.github.com/steipete/d9b44d8e9f341e81414e86d7ff8fb62d

For Xcode 9.0 beta and iOS 11.0 beta (name your Xcode9.app for Xcode 9 beta and Xcode.app for Xcode 8)

sudo ln -s "/Applications/Xcode9.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/11.0\ \(15A5278f\)" "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport"

Supertonic

This is the correct answer if you don't want to upgrade to the latest version of Xcode yet. – Garget

Thanks for the tip! It worked really well and now I can debug on my iOS 10 device from Xcode 7. This is a life saver for those working on Swift 2.2 projects not ready to upgrade to Swift 2.3 or Swift 3. Thanks! – Peterkin

While code often speaks for itself, it's good to add some explanation to your code. This popped up in the review queue, as code-only answers tend to. – Stocktaking

For Xcode 8 beta 4 & iOS 10 beta 4, use following line: sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.0\ (14A5322e) /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport – Shuddering

For Xcode 8 beta 5 & iOS 10 beta 5: sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.0\ \(14A5335a\)/ /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport – Jaggery

Xcode 8 beta 6 & iOS beta 6: sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.0\ \(14A5339a\)/ /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport – Jaggery

If you had Xcode 7 running when you made the softlink, exit out and restart Xcode afterwards. – Deanery

I had to use the following command for Xcode 8 and Xcode 7.3.1 sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.0\ \(14A345\) "/Applications/Xcode\ 7.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport, where I had renamed my Xcode.app file to Xcode 7.app for my Xcode 7 installation. Xcode 8 was called Xcode.app. Note the 14A345. You can check this number on your system by looking in the directory on your Xcode 8 install. – Catholic

@Catholic posted then saw your post :) to all: follow the above for the release versions that came out yesterday! I did the same thing to get it working – Radiopaque

Answer 6

My problem was with Xcode 7 and Xcode 6.4 beta and iOS 8.4 - device not compatible.

In case of the same problem for better understanding how to fix, do next:

1. Go to /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
2. Go to
   /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSup‌​port/
3. Copy folder iOS 8.4 in another folder

4. Restart Xcode

Soares

I think I am in similar situation, but I cannot find the 8.4 folder in either path. My iPhone runs a 8.4(12H143) and it says no more updates available. Do you have any suggestions? – Kosey

you can only find iOS 8.4 if you install 6.4 xCode I have both xCode 7 beta and xCode 6.4, if you have only xCode 7 - that's can be a reason why you cant find it – Soares

This solution also works for iOS 9.1 beta and Xcode 7.0. – Odelsting

What do you mean by "another folder" @Kirill? I'm using iOS 9.1 Xcode 7.0 Beta 6? – Impervious

This saved me from a 4GB download to upgrade XCode 7.2 to 7.3 – Tradesfolk

Working great getting tvOS & iOS 10 Beta working on xcode 7.3, Thanks! – Newt

working great with xcode 7 and the release of xcode 8 & ios10.. great answer even if it might be a bit hacky :) thanks – Church

Answer 7

If you have iOS 9.1 on your phone, just download Xcode 7.1 beta instead of using GM.

See Apple's response: Could not find developer disk image for iOS 9.1

Bogie

It also works to copy the device folder from Xcode 7.1 version into the GM Xcode 7, as in the @Kirill answer. – Kobylak

Answer 8

I got the same error message (Couldn't find developer disk image) after I updated my devices to iOS 9.2, but forgot to update to Xcode 7.2.

So in my case, the fix was easy: just update to Xcode 7.2 via Mac App Store.

Hush

What if my AppStore says Xcode already updated to 7.2, but when I open it it still says 7.1.1? T_T – Decomposed

Open Xcode. Click on the menu item 'Xcode' -> 'About Xcode'. What is the version number? You should see this: Version 7.2 (7C68) – Hush

Nop, I saw 7.1.1. I had to uninstall Xcode and install it again to get the newest version – Decomposed

Just had a similar issue, @gfpacheco. My issue was I wasn't logged into my apple account, but the prompt to log in didn't come into focus (because it was already open from elsewhere, but minimized/hidden). I thought I was updating the software, but was not really. – Maneating

Answer 9

This message appears when your version of Xcode is too old for the device's version of iOS. Upgrade Xcode to the latest.

If the App Store doesn't offer an update for Xcode, upgrade to the latest Mac OS. In the past, Apple has been rather aggressive about dropping support for past versions of Mac OS X in the latest Xcode.

EDIT: yes, this error started popping up all over again. :) Xcode 7.3.1, which is the latest one that's available for MacOS 10.11 (El Capitan), doesn't support iOS 10. You need MacOS Sierra (and possibly a new Mac).

Nosography

Answer 10

I just got this, and I'm on Xcode 7.2.1... It appeared when I downloaded iOS 9.3. Check your Project -> Base SDK and if it isn't the same or ahead of your device version, then that's the issue. I didn't see anything in the "Updates" section, but when I searched "Xcode" in the App Store it had an update for 7.3.

Upgrading to iOS 9.3 and Xcode 7.3 requires Mac OS X v10.11 (El Capitan) for Xcode to run, and that's why auto update isn't upgrading Xcode versions.

Fuchsia

Answer 11

This problem is a mismatch of your iOS version and Xcode version.

Example:

You have an iPhone with iOS 9.3 GM and your Xcode version is 7.2.1. This leads to the issue that you have to update your Xcode to 7.3 which includes SDKs and related stuff for iOS 9.3.

Atomizer

If you also gave instructions on how to update Xcode, then this would be the best answer by far, all of the top answers are too specific to a version of xcode. – Marty

Answer 12

There actually is a way to deploy to a device running a newer iOS that the particular version of Xcode might not actually support. What you need to do is copy over the folder that contains the Developer Disk Image from the newer version of Xcode.

For example, you can deploy to a device running iOS 9.3 using Xcode 7.2.1 (which only supports up to iOS 9.2) using this method. Go to the Xcode 7.3 install and navigate to:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

From here, copy over the folder that contains the version you are trying to run on the older version of Xcode (for this example, it's 9.3 with the build number in parenthesis). Copy this folder over to the other install of Xcode, and now you should be able to deploy to a device running that particular version of iOS.

This will fail, however, if you're utilizing API calls that were specifically added to the newer version of the SDK. In that case, you will be forced to update Xcode.

Eocene

Sounds like a great workaround but, unfortunately, doesn’t work with Xcode 9.3.1 and iOS 10 Beta 2 (kAMDMobileImageMounterDeviceLocked error) – Nea

Darn...I haven't tested it yet with later versions of Xcode and the iOS 10 beta. Maybe this is due to the fact that the version of iOS is in beta? If not, then we might need another workaround for the future. My machines are still running Yosemite so I'm going to need to do something soon. – Eocene

This was a real lifesaver! Dev phone was upgraded to iOS 9.3, but we still need to test production code in Xcode 7.2.1 while the Swift 3 branch is is in development. Why Apple doesn't at least allow developers to maintain a broader range of device/development versions is beyond me. – Specht

Yeah, that's a similar situation that I used it in. However some people are now reporting that it no longer works with Xcode 8.0 and iOS 10 😕 – Eocene

Answer 13

I have experienced the same issue:

Could not find Developer Disk Image

My Xcode version was 7.0.1, and I updated my iPhone's version to 9.2, and upon using Xcode I ran into this problem.

The solution is pretty simple: Just download the latest version of Xcode 7.2 which was released on 8 Dec, 2015 and install it. Everything works fine for you as it was before.

Note: The actual problem is your Xcode version is not compatible/outdated with the version on your device.

Radicalism

Answer 14

This error is shown when your Xcode installation is too old and the related device you are using is updated to latest version.

There are multiple ways to solve this issues.

1. Update your Xcode installation.

This is by far the simplest method. Just update your Xcode installation to the latest stable version and things would start working again.

Note: Please update your OS as well if Xcode doesn't support your current OS. Which brings us to...

2. Manually copying Device Disk Image. No update needed.

This is the clever way around. You don't have to update your Xcode installation or your OS for this.

First open the XCode.dmg and select Show Package Contents.

Phase 1: Getting the downloaded Xcode ready.

Steps:

1. Download the latest Xcode.dmg from Developer portal.
2. Select the downloaded Xcode.dmg and right click on it.
3. In the options, select Open With → DiskImageMounter.
4. Now in Finder, open the Xcode disk.
5. In the disk, right click on Xcode.
6. Select Show Package Contents.

Now, a new finder window opens. Follow the instructions below to copy the disk image.

Phase 2: Copying the Developer Disk Image.

Steps:

1. In the new finder, go to Contents.
2. Inside Contents, Go to Developer.
3. Inside Developer, go to Platform.
   Now select the desired platform. For our purpose, we are going to update iOS disk image only.
4. Inside Platform, go to Device Support.
5. Inside Device Support, you'll find a lot of disk images. This includes the latest device disk images as well.
6. Copy all the folders inside Device Support. Select all and then copy.

Note: For step 6, You can copy the disk image you want to copy as well, i.e. copy the latest only. It's the last folder in the hierarchy here.

This ends the Phase 2, Copying the disk image. Now in the next phase, we will update the developer disk image of our Xcode installed on our device.

Phase 3: Upadting the Xcode's developer disk image.

Now, close all the finder windows for faster operation and less confusion.

We are now going to update our Xcode's disk image for iOS Platform.

Steps:

1. Close the Xcode application if it is open.
2. Open a new finder window.
3. Select the primary partition if you have multiple partitions.
4. Go to Applications.
5. Find XCode and right click on it.
6. Select Show Package Contents.

Finder window updates or opens a new window with Contents as the main directory.

7. Select Contents.
8. Inside Contents, select Developer.
9. Now, select Platforms.
   10. Now, select iPhoneOS.platform.
   11. Inside iPhoneOS.platform, go to Device Support.
   12. Inside Device Support, select all the files and Move to Trash.

Note: SKIP step 12 if you copied only the latest disk image i.e. the last folder in the hierarchy.

Now, Paste the developer disk image we copied from Phase 2 here.

13. Final Step, right click and Paste here.

If everything worked properly, your Xcode has new developer disk image. Close the finder now, and open Xcode. The error should be gone by now.

Reminder: Don't forget to unmount the Xcode now from finder as well.

Excellent workaround in case you can't update XCode! Worked perfectly. Probably worth adding a link to how you get the .dmg for XCode directly: #10336247 – Divisor

Answer 15

It works, in my case for Xcode from 7.3 TO 7.1. Copy directory 9.2, for iOS device OS 9.2.1.

Matelot

Answer 16

As others suggested, this issue is caused by an incompatible iOS version (which is higher than the maximum version that Xcode supports). Normally it can be addressed by updating Xcode, but sometimes you may be restricted to do so, hence here's another workaround.

Head to developer.apple.com/downloads (or google similar stuff if this link dies) to grab the newest Xcode dmg image manually, and then mount it. If you're doing this already, the new Xcode is not likely working for you, but you can cp /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/NEW_IOS_VERSION /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/ to copy the image you want into the old Xcode you've installed.

Of course it's not guaranteed to work for future versions, but it's definitely worth trying. For me, my iOS version is 9.3.1 (13E238), but I copied 9.3 (13E230), and it works just fine.

Patterman

Answer 17

This happens when your Xcode version doesn't have a necessary component to build the application to your target OS. You should update your Xcode.

If you are building a new application for a beta OS version that no stable Xcode version is able to build, you should download the newest Xcode beta version.

I also had this problem. I was using Xcode 7.3 for my iOS 10 beta iPhone, so I went to install Xcode 8-beta, and I did the following step to continue using the stable version of Xcode with new build tool:

Just like @onmyway133 answer, but more user-friendly is after finish installing the Xcode 8-beta version, go to Xcode 7.3 preferences (Cmd + ,), go to the tab locations, change the Command Line Tools to Xcode 8 in the dropdown list.

I successfully built to both iOS simulator 9.3 and my device iOS 10 beta using Xcode 7.3.

Whoso

Answer 18

This problem is fundamentally rooted in the mismatch of your iOS version and Xcode version.

Check the compatibility of iOS and Xcode.

Go To Application folder (In finder) -> right click on Xcode -> click on show package contents -> Double click contents folder -> Double click developers folder -> Double click platforms folder -> Double click iPhoneOS.platform folder -> Double click device support folder -> then add latest developer disk image.

Or

Download Latest version of Xcode.

For iOS 10 beta 7, add the following link on the command line:

sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.0\ \(14A5339a\) /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

Answer 20

Just my two cents for iOS 10 (under NDA, but for people that can use it legally...)

• Copying full folder (as other people said) works
• Symbolic link seems not.

This was tested using Xcode 7.3 (std from Store) AND iPhone 6Plus with 10.0 (14A5261v).

Serles

as per beta 6 seems to work: sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.0\ \(14A5339a\)/ /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport pls remember to quit and reopen Xcode – Serles

Answer 21

I have also faced this issue, and I'm on Xcode 7.2.

It appeared when I downloaded iOS 9.3.

Check your Project -> Base SDK and if it isn't the same or ahead of your device version, then that's the issue.

I didn't see anything in the "Updates" section, but when I searched "Xcode" in the App Store it had an update for 7.3. Upgrading to iOS 9.3 and Xcode 7.3 requires Mac OS X v10.11 (El Capitan) for Xcode to run, and that's why auto update isn't upgrading Xcode versions.

Answer 22

by the way it DOES work even in Xcode Version 8.3.1 (8E1000a) adding an image for iOS 11 beta. I added 11.0 (15A5278f) inside

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/

and works with my iPhone 7plus with new iOS 11 beta.

Answer 23

New Updates for iOS Device Support file. Don't need to update Xcode.

You just need to add support file to Xcode's DeviceSupport folder.

iOS 11.3 Developer Disk Image

iOS 11.4 Developer Disk Image

iOS 12.3.1 Developer Disk Image

iOS 13.0 Developer Disk Image

Extract the zip and then copy folder.

In case you came here because you experience this issue while using Xamarin Hot Restart from within Visual Studio on Windows, it could look like this:

Launching '' on 'iPhone'... Connecting iOS Debugger to '' over USB on port 10000... There is no developer image available to mount on '' with version '15.3', so the app '' will not be launched automatically Please launch the application '' on the device '' to continue

If this is the case you might have updated your iPhone to a new version and forgot to also update your iTunes installation that you got from the Windows Store.
