I am now getting this crash since installing Xcode 12 beta 6. I was not getting it in any of the previous betas. It happens on every launch, same assertion failure and callstack as above.

Same problem occurred many times after reinstall Xcode app.

The solution was:

  1. Open a random swift file (eg. AppDelegate.swift)

  2. Open the project.

  3. Clean the build folder (Product->Clean Build Folder)

This method worked for me, I don't know why!
