I work on a project with a friend, can we use the same "bundle id"?. When I clone a project, and try to build it i got the error: "The app identifier "bundle id" cannot be registered to your development team.", then i change bundle id, and it works. But I don't want to do it each time i pull the new code from the server. How do I manage this ?
By changing bundleId on both devices, you are changing the signature of the app. Basically saying, you are splitting it into 2 different apps for AppStore. Bundle id should be unique for one app everywhere. As I see you have a problem with different developers accounts that want to use the same bundle id. Just try to add another developer to your Apple Developer Account giving an App Manager or Developer role, so he/she can work with any reserved bundle id's in your account. I highly recommend you to read iOS Development Team Administration
