I’m experiencing frequent crashes in both Xcode 16 and Xcode 16.1 Beta when adding an object or a constraint in XIB files. This also happens with XIB files I created in Xcode 16. The crashes make it impossible to work on my project. Has anyone else encountered this issue? What can I do to resolve it?

I was wondering what kind of weirdness I would encounter with the new Xcode, but I didn’t expect a problem of this level. Apple has surprised me once again.

Xcode crash log:

I tried to add a button, label to the view in a XIB file, and Xcode crashed. The same thing happens when I try to add a constraint.
