build settings specify a provisioning profile with the UUID
I'm using XCode 7.2 and saw this problem. Restarting XCode solved this for me. Not sure it will always solve the problem, but you may want to try this first.
I know its too late to put an answer here but this question comes up at the top after searching this issue. I managed to solve this by selecting the project and in Build settings changed the UUID options to what I wanted.
If you are now using Xcode 7.2, it appears you will receive this message if you download individual profiles either from the Developer Center or from Xcode > Preferences > Account. Select Team Name and View Details > Provisioning Profiles section. I downloaded individual profiles (I've got several dozen so its hard to find a particular one) and was running into this error. Even if you select Download All after downloading individual profiles, this error still comes up.
You will need to find the Provisioning Profiles and delete them then select Download All. Easiest way is to right click on a profile in an Account's details that is already downloaded and select Show In Finder and delete them all. Then just select Download All and hopefully your profiles will match up to your Code Signing.
