After update to Xcode 7.3 I am getting errors while trying to submit my app on beta testing via TestFlight. It is very strange because I have managed to submit more than ten build with the same App Id.
I am making an archive and tap on Upload to App Store As the result I am getting and error:
"You account already has a valid iOS Distribution certificate. You have a valid iOS Distribution certificate in the Member Center, but it is not installed locally. If your signing identity is installed on another Mac, you can export a developer profile on that Mac and import it on this Mac. You can also reset your current certificate."
If I tap cancel on this warning message, I get the new one:
"Xcode attempted to locate or generate matching signing assets and failed to do so because of the following issues. An App ID with identifier 'com.abc.Defg' is not available. Please enter a different string".
