I accidentally deleted the Team Provisioning Profile:* in the Provisioning Portal, what should I do now? :/
In September 2015, I fixed this by launching Xcode 6 and creating a new project. I followed this guidance from Apple's troubleshooting documentation, and it fixed my problem:
If a warning message and Fix Issue button appear below the Team pop-up menu in the General pane or in a section of the Capabilities pane in the project editor, read the message and click the Fix Issue button.
I now have a wildcard team provisioning profile back in the developer portal.
