In summary, I can run the debug of my app on the local mac simulator just fine. But, I get errors when I try to Build B4i-Bridge app in order to start debugging on a real device.
Update... I uninstalled B4i and reinstalled. Same problem.
I installed B4i onto a clean computer (never before had it installed), went through the process of creating new certificates, provisioning profiles, etc. and ... it works.
So, what did I do to mess up the first computer? THAT is the computer that B4i MUST run on.
