When I try to open another project everything is fine, it's just this specific project.

I've tried to restart my Mac and it still crashes.

Anyone know how to fix this?

Thanks!

Answer 1

To fix this problem:

open a Finder window and navigate to your project right-click on the .xcodeproj file (it’s a package actually) select Show Package Contents a new window appears delete a folder called xcuserdata Now open your project again in Xcode and it should work. Your workspace will be reset, bringing a very small amount of happiness and tranquility back into your life.

Answer 2

Nothing work for me. I delete my .xcworkspace and regenerate .xcworkspace by pod install and work for me.

Answer 3

Do one thing, clear off/delete all the derived data for Xcode and then open your project. That should fix the issue.

Also to report a bug to Apple you can simply go to https://bugreporter.apple.com/ and login with apple credentials and and they'd get back to you in like couple of days.

Also for derived data do the following: You can go to File > Workspace Settings if you are in a workspace environment or File > Project Settings for a regular project environment.

Then click over the little grey arrow under Derived data section and select your project folder to delete it.

Answer 4

In my case, it was resolved by:

"I was able to get unblocked by deleting project.xcworkspace/xcuserdata in my project"
