I have a project on TestFlight and I tried renaming it using the steps from this video on youtube: https://www.youtube.com/watch?v=jRnVjtNLLLk
After archiving and trying to upload this to the test center I am getting the error:
Missing IOS distribution signing identity for Name. Xcode can request one for you.
This app uses the Icloud. I'm not sure if I have to change anything there or not. I have tried using the old tables(old name of project) and the new tables(new name of project).
The issue is because the Apple WWDRCA expired two days ago. (Feb 14, 2016): https://developer.apple.com/support/certificates/expiration/
Authority from both the login and System Keychains. Install the renewed certificate from Apple by downloading from https://developer.apple.com/certificationauthority/AppleWWDRCA.cer
then opening it.
Also you will need to do restart Xcode to reflects the changes -> Clean your project -> Build then try again to generate your archive. Ref:
Thanks.
