Ultimately switching from UI_USER_INTERFACE_IDIOM() to UIDevice.current.userInterfaceIdiom in a dependency also did the trick (didn't have to disable bitcode in that case).

Can confirm that turning off bitcode in a linked framework did the trick with Xcode 13.3.

Seeing the same issue with https://github.com/suzuki-0000/SKPhotoBrowser. Has anyone found a reliable fix?
