@idcrook thanks for your post! I ended up changing my shell from zsh to bash and the debugger started to work again.

Finally got this to work. Try changing your shell from zsh to bash (then back if you need to). See my answer here. https://developer.apple.com/forums/thread/651375

Hey @idcrook ive tried removing all my .zsh files in my home directory but still getting the same issue. Where exactly did you find your csh-backed shell utility? was that in your homre directory?

Still getting this on Xcode 12.4 Intel Macbook Pro Big Sur 11.1. I've tried removing all my zsh dot files like @idcrook said but it still says "Cannot create Swift scratch context (couldn't create a ClangImporter)". On a brand new user account it does work though. Please let me know if anyone has any other ideas to try.

@Burnsides were you able to reproduce applicationState == .background within didReceiveRemoteNotification? When would such a case occur? when it does occur should the navigation still happen? Every time I try to reproduce, applicationState == .inactive.

Anyone figure this out?

Same here - (the back animation has the same issue)
