Answer 1

I just had this issue today, seems to have been caused by my cache being corrupted somehow; perhaps a charset issue? No idea, but the solution that worked for me was the bash script in this Gist.

It clears the cocoapods cache so that you get a fresh copy of all required when you next run pod install. Fixed my problem immediately, confirming my suspicion, and hasn't reoccurred since.
