I ran a Touch ID sample Code, and I changed the Bundle ID, the last builded App was OK, but the previous one with different Bundle ID was failed with error:
Touch ID Error:
Error Domain=com.apple.LocalAuthentication Code=-1004 "User interaction is required." UserInfo={NSLocalizedDescription=User interaction is required.}
Does anyone has the same problem? Same code with different Bundle ID, only the last builded one was OK .
