Xcode Error: “The app ID cannot be registered to your development team.”

Question

We are porting an Android app to iOS for a client. They have added our account to their iTunes Connect account and created an app entry. We developed the app using the bundle ID

Answer 1

This happened to me, even though I had already registered the Bundle Id with my account. It turns out that the capitalisation differed, so I had to change the bundle id in Xcode to lowercase, and it all worked. Hope that helps someone else :)
