Hi,
As Erel suggested, I requested a temporary hosted builder account and it works fine and I can compile my code.
But I have noticed something strange. While I was trying to solve the problem using my mac, a project in xcode was open. The general tab under project settings was selected and just as I tried to build b4i-bridge app on my mac, a button titled "Revoke" appeared under certificate selection with a text above it saying the following:
Revoke certificate Your account already has a signing certificate for this machine but it is not present in your keychain. To create a new one, you must first revoke the existing certificate.
After that I couldn't compile the Xcode project either. In the end I had to remove all my certificates, etc and re-create them to get Xcode to work.
