Keep attention in:
a) To have a right App-Specific Passwords as say the AI2-iOS Building Apps for iOS with MIT App Invento. If you have built problems, better generate a new in your Apple Id and put it in the AI2 Settings.
b) Very important. In the Provisioning Apple Profile names not put names with the characters "-" and not "_". Only normal abc characters.
For me all is is running well send to Apple Connect the abb Builders from Ai2.
