Xcode quits unexpectedly every time I open my project

Question

After opening xcode, when I open my current project, it's showing a warning like "xcode quit unexpectedly" with 3 options: "Ignore", "Report" and "Reopen". When I click "Reopen", it will open the xcode window and again automatically it will close and show the same warning.

Why this is happening? If I open any other projects, then it opens with no issues; the issue is with my current app.

versions:

• xcode is 4.3.1
• mac OS X version is 10.7.3

Please tell me why it's happening like this.

Answer 1

Xcode stores some user state information inside the Xcode project “file”, which is really a folder. That state information might have become corrupted. You can normally throw away everything inside your .xcodeproj folder except the project.pbxproj file. This might fix your problem.

Open up the folder containing your .xcodeproj file. Right-click or control-click the .xcodeproj file and choose “Show Package Contents”. Then throw away everything except the project.pbxproj file.

If you know what an Xcode workspace is, and you're actually making use of it, you might not have a project.xcworkspace file to throw away, or you might not want to throw it away. But if you don't know what an Xcode workspace is, then you're not using it so you can just throw away project.xcworkspace. Xcode will recreate it automatically.

You are the man ! I personaly went on biogaran.xcworkspace and removed the folder xcuserdata – Boote

Nice graphic but this didn't fix it for me-!! My issue was xcodes built in version control - solved by https://mcmap.net/q/330756/-xcode-5-crashes-xcode-quit-unexpectedly – Meaningful

Its not solving my problem yet. i am able to open xcode 8 but in xcode 7 still getting same alert again and again. – Awoke

After doing this I had recreate my build schemes in order to build and run. – Tonie

I was using a workspace - did the same thing on my .workspace file and it worked :) – Akers

Deleting just UserInterfaceState.xcuserstate file fixed the issue – Sibelius

It might also help to download a fresh git clone of the project - if the xcuserdata etc are ignored, you should get a clean version. helped here. – Twylatwyman

Answer 2

Deleting Derived Data worked for me. Just open another project or open xcode without opening your corrupted project. Than open preferences and go locations tab at the end. Click gray circle with arrow (where all your projects derived data are saved.)

Delete your corrupted project's derived data in there and you are good to go.

If you're using CocoaPods, just follow Rob's instruction but on the .xcworkspace file instead and do not delete the .xcworkspacedata file.

You're right but they can make clean cocoapods installation if it is necessary. – Reverberatory

Answer 11

It's 2021, still having this problem. Reboot doesn't help, OS update doesn't help.

Then I updated everything in the App Store (iMovie, Numbers, Pages, Keynote) and Xcode is now working.

Please don't ask why.

Answer 12

I am using CocoaPods, and followed Rob's Instruction on the .xcworkspace file as indicated above by Allecto. After I "showed Package Contents" on the .xcworkspace file, the only thing I did was to rename the xcuserdata folder to xcuserdataCrashApril2. I was then able to open the project (workspace) with no problems. The only difference is xcode did not save the state of which .swift source code files were previously opened (which is not a big issue for me).

I suppose I can delete the xcuserdataCrashApril2 file, but I am keeping it out there as a reminder of what to do the next time this happens.

All the advices from above didn't help me so I added the pod file via pod init & pod install and successfully opened newly created .xcworkspace. Hope it helps somebody
