One more solution.
In Release configuration I successfully built my app, but in Debug - had the same issue, as in topic.

Go to your startup Project-> Options -> Build -> iOS Bundle Signing. Then check your Signing Identity and Provisioning Profile for each Configuration Debug and Release.

In my case Release configuration was setup-ed correctly (several days ago by me) with values:
- Signing Identity: Developer(Automatic)
- Provisioning Profile: Automatic

But Debug configuration was silently corrupted somehow:
- Signing Identity: Unknown (Iphone Distribution: name of my company)
- Provisioning Profile: No matching profiles found

Thus, fix your Debug configuration to be equal with Release.
