I’m working through the “Develop in Swift Fundamentals” with Xcode 13 book. At this point I’m trying to set up my iPhone as as a testing device. I’ve turned on developer mode on the phone, but when I select my iPhone from the Scheme menu, I receive 2 errors referencing my Bundle Identifier: Failed to register bundle identifier. The app identifier "com.example.GettingStarted" cannot be registered to your development team because it is not available. Change your bundle identifier to a unique string to try again. No profiles for 'com.example.GettingStarted' were found. Xcode couldn't find any iOS App Development provisioning profiles matching 'com.example.GettingStarted'. I am not sure why that bundle identifier is not available. Any thoughts on how to proceed?
