Since updating to Xcode 16, I’m experiencing a critical issue with my iOS project. Whenever I try to access a XIB or Storyboard file, Xcode crashes instantly. I can only access the XIB files by viewing them as code; attempting to open them in Interface Builder causes a crash. I also cannot create new Storyboard or XIB files because creating them causes Xcode to crash as well.
Also, I can open my xib alone in xcode, without opening the project, and in this case, it’s working but useless.
Here is the crash report
Process: Xcode [50503]
Version: 16.0 (23051)
...
Exception Type: EXC_CRASH (SIGABRT)

I Checked and tried to modify Version Numbers in XIB and Storyboard Files.
I Performed a clean build.
I Deleted Derived Data.
I updated dependencies and cocoapods
I Uninstalled Xcode 16 and reinstalled it.

I had an issue when using SourceTree to copy apps, but I fixed it by cloning an app via URL in Xcode. When using Xcode’s ‘clone from URL’ feature, it asks for permission, and after that, my issue was resolved.
Update to Xcode 16.2. They fix this problem.
