Answer 1

The problem is with the Developer Certificate on Keychain which is under "System", on the left hand panel, which is always locked and requiring my password to unlock!

So just move the Developer Certificate to "login", which is always unlocked. Now your problem gets solved.

It seems that Xcode not refresh the team selection so selecting it again from the general tab of the targets solved it.

Answer 3

I was getting this problem because I had duplicate certificates in my login and System keychains. By opening Keychain Access and deleting all certificates from System that were also in login solved this problem. Hope this helps.
