Question

I am not new to this but I am unable to fix my signing identity from Xcode Version 6.2 (6C86e). When I click fix issue on the following message:

Answer 1

In my case the solution was:

1. Xcode: Preferences / Accounts / View Details...;
2. Click refresh (bottom left);
3. "Certificate Not Found" box pops-up with

"Your Mac Development Certificate for “your name” was not found on the Member Center. Xcode can submit a certificate signing request on your behalf. Would you like Xcode to do so now?

4. Click Request and tick all certificates in the next screen;
5. 15 sec of waiting and the issue fixed.
