I am running into a crash issue with what seems like a super simple project. This all works in Preview up until the home button is pressed in the Info view. It flashes back to the Colors list, then crashes. Interestingly, it works in the Similar with no issues. This is on an M2 Pro MacBook Pro running Ventura/Xcode 13.3.1. I haven’t upgraded yet because I have read enough horror stories about Sonoma, especially with respect to Parallels Desktop, which I need to keep running for a little longer.
My question is, is this a problem in my code that I am missing, or a bug that I just need to work around and accept for now? And, is there anything in the crash dump that might be helpful? I have looked through it and I can’t find anything that defines WHY I got a crash, but it might as well be in Klingon as far as my comprehension of what I am reading. 🙂
