I'm getting the following error:
Code Signing Error: Signing for "AppsMobileCompany" requires a development team. Select a development team in the project editor.

I'm getting the following error:
Code Signing Error: Signing for "AppsMobileCompany" requires a development team. Select a development team in the project editor.

EDIT: Apple has since updated Xcode and as a result, picking your team is now in the Signing & Capabilities tab.
You need to select your team in the general tab. If you have not set up a team you can set it up at developer.apple.com
