Fixing codesign exits with return value of 1

Every other time I was trying to build and run for an ios device, I was getting a codesign exits with return value of 1. Here's the steps that fixed it.

Remove all .mobileprofile files that have GUID filenames from ~/Library/MobileDevice/Provisioning Profiles

Copy in your .mobileprofile file that you have just downloaded to that directory. It should not have a GUID filename. That fixed it for me.
