Could not run build/ios/iphoneos/Runner.app on Try launching Xcode and selecting "Product > Run" to fix the problem

Question

When running an iOS App on a real iPhone (not Simulator) you may run into this problem.
The reason is because the app isn't signed by a trusted source.

Answer 1

To fix this you have to Open Settings on your iPhone and navigate to: General -> Device Management, then select your Developer App certificate and "trust" it.

• Update: it may now be called General -> VPN & Device Management

I dont have anything like "Device Management" on my iphone 7 - ios 14.2 – Sisera

Same as marhyno: Nothing like "Device Management". iPhone XR iOS 14.7.1. – Ernieernst

This worked for me after updating the signing profile, took a few tries for it to appear. The menu item is now called "VPN & Device Management" – Vestibule

@ Webkraft Studios I see "VPN & Device Management", but there's nothing there to "trust". What did you try a few times for it to appear? – Dreamworld

then select your Developer App certificate I don't this option to select an app – Alate

Answer 2

Device : iPhone XR and iOS version: 15.4

1. Open Settings > Developer
2. Click on Clear trusted computer
3. Then click on trust this computer

Thanks, this worked for me. Out of nowhere, VS Code and flutter threw this error, and it ran fine in XCode. Cleared the trusted computers, then it ran fine in VS Code. – Vestry

This, plus flutter clean & flutter pub get. Thank you! – Racer

Answer 3

For those having this issue on IOS 17 and Xcode 15, Just upgrade Flutter to at least version 3.13 where this issue has been solved

you may want to try running it multiple times before it works properly

This is correct for people having this error after upgrading to iOS 17, which was my case. Thanks ! – Punch

That works. Just upgrade flutter to the latest version! – Traction

I confirm that this solved the issue on my side as well. Thanks for this ! – Guardsman

Need a solution without upgrading flutter... – Carlton

@Carlton check if this works for you https://mcmap.net/q/386038/-could-not-run-build-ios-iphoneos-runner-app-on-try-launching-xcode-and-selecting-quot-product-gt-run-quot-to-fix-the-problem – Plowshare

Answer 4

Same issue here, I only solved it after uninstalling the app and run it again.

Answer 5

Some Settings are changed in IOS 17 and New MAC OS Version. So we have to Upgrade Flutter Version 3.13.0 Minimum. For Single Project you can try with FVM (Flutter version Manager). No Other solution is working for me so I have to use this.

Ascetic

This is the only solution that worked for me. Not the ideal solution as I need to upgrade my entire project to support upgraded Flutter, but as a hotfix. – Foghorn

Answer 6

What worked in my case

A simple

flutter clean
flutter pub get

did solve the issue

What I tried before (and did not solve the issue)

1. Run the project via Xcode > Product > Run

2. Clear trusted computers by doing the following steps on iPhone

   • Settings > Developer > Clear Trusted Computers
   • Trust this computer

Answer 7

1. Go to your device Settings
2. Go to General
3. At the bottom you may find Transfer or Reset iPhone option, select that. (Be careful selecting anything here)
4. Now choose Reset option and select Reset Location & Privacy. (Enter your pin to confirm. After few second it will prompt the trust this computer option.)

In Shortcut you can go Settings>General>Transfer or Reset iPhone>Reset>Reset Location & Privacy or directly search for Reset then choose Reset Location & Privacy

Now you will find the previous trusted app in Device Management. Please remove if you have same. Now re-run

Answer 8

Xcode was configured with an ad hoc profile instead of a dev profile, changing that fixed it.

Answer 10

On iPhone 7 going to Settings and clearing trusted computers with further build clean did the trick for me

Answer 11

I ran into this issue when I had a very low wifi connection. The low connection would cause this issue intermittently. Fixing the wifi connection fixed this issue for me.

(In my case, I needed to reset my wifi settings on my iPhone).

Answer 12

I had this issue when I tried to install a different version of the same app (store and dev). All I needed to do was to fully uninstall all versions of the app from the target iPhone. Might not work in every case, but easy to try.

Answer 16

The issue relates "Privacy & Security" from your macos. You need to allow Android Studio app to access Xcode.

Settings -> Privacy & Security -> Automation -> Android Studio -> Xcode: toggle ON
