I have this problem too. Adding a ".navigationViewStyle" is not solving either. I am using Xcode 13.3 on MacOS 12.3 using Apple Silicon.

See Apple documentation at this link: https://developer.apple.com/documentation/bundleresources/information_property_list/cfbundleidentifier This reads: "For watchOS apps that have a companion iOS app in the same project, the embedded WatchKit app and WatchKit extension targets must have the same bundle ID prefix as the iOS app. The WatchKit app must have the format [Bundle ID].watchkitapp, and the WatchKit extension must have the format [Bundle ID].watchkitextension."
