I am a total newbie to software development with swift, so maybe this is quickly answered.
I am running Xcode 11.1 on macOS Catalina 10.15. Everything seems to work fine, when I write my own code from scratch. However, when I download examples from Apple (as for instance recommended in Chris’ tutorial “Swift UI Navigation & Lists”) I cannot build and run the code due to the following error:
Failed to register bundle identifier. The app identifier “com.example.apple-samplecode.Landmarks” cannot be registered to your development team. Change your bundle identifier to a unique string to try again.
I tried to change the bundle identifier, but it seems that I do not fully understand where it has to be changed and to what I need to set it.
In “Signing & Capabilities” signing is automatically managed, the team is my Name (personal team) and the signing certificate is Apple Development: myAppleID
Thanks for any help
