Can't create provisioning profile in Xcode 9

Question

I tried downloading a fork of moonlight-ios to run on tvOS and I got some errors. I fixed one of them by learning how to sign the app and had to change Bundle Identifier to something unique to get it to work.

But then the app had a bug, and didn't work. So I downloaded another fork which claimed to have fixed this bug. But now I can't sign the new project. Whatever I try to enter in the Bundle Identifier gets rejected, and I get the errors:

Failed to create provisioning profile.
There are no devices registered in your account on the developer website. Plug in and select a device to have Xcode register it.

No profiles for 'com.example.GettingStarted42365436' were found
Xcode couldn't find any iOS App Development provisioning profiles matching 'com.example.GettingStarted42365436'.

I've done this so many times I've gotten to the 10/week limit now and can't try new identifiers. What am I doing wrong?

Answer 1

I fixed it. Seems the project manager was stuck on the previous project and when I tried to sign the new one I infact tried to sign the new one without actually changing anything in it

Answer 2

Go to Xcode > Preferences > Accounts and make sure that your accounts have been set up properly. I had the same problem couple days ago after updating to the new version of Xcode.
