I just started with the first book from Apple entitled "Develop in Swift Fundamentals". When trying out my first lesson to execute a simple, blank app to my iPhone, the program fails to build and gives me the following errors under Signing and Capabilities: Failed to register bundle identifier The app identifier "com.example.Test" 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.Test' were found Xcode couldn't find any iOS App Development provisioning profiles matching 'com.example.Test'. I don't have a clue what's going on here and Apple hasn't helped me at all. Any ideas?
