I'm trying to use Xcode UI tests for the first time. I added a UI Tests target and set up the signing, then opened the default AppnameUITests.swift file. I added a new function named testAboutPage(), clicked inside the block and clicked the Record UI Test button (red circle) at the bottom of the editor window. If the app is already running when I do this, Xcode crashes immediately. If the app is not running, Xcode builds and runs the app, then crashes.
I've seen reports of this going back years, but none of the posts have a solution. I do have a crash log to share. Does anyone know how to get past this?
This forum won't let me upload the complete crash log because it exceeds the size limit, but here's the first part through the stack trace of the crashed thread:
