In Xcode 6 you would click on Xcode -> Preferences -> Account -> View Details -> then there would be a little circular arrow. That is gone and there is now a \"Download All\
Sometimes XCode 7+ does not automatically refresh provisioning profile. I removed apple id from Xcode -> Preferences -> Account and then added again. There was download button instead of newly updated profile. Click download. Close XCode and open again. It should work perfectly.
