  • I found that if you open the project with the .xcodeproj and let it finish the indexing and then open the project with the .xcworkspace to open the project , the crash will not happed , I use this method with Xcode 15.4 beta , maybe you can try it i

I have the same issue with one of our project.

Could the develop supporter to check out this issue?

The steps to reproduce this issue:

  1. Open the project
  2. Just waiting, then xcode will be indexing
  3. About 2 seconds later, it crashed.
