I deleted the default Xcode managed "iOS Team Provisioning Profile". I couldn't get it to work because of "Valid signing identify not found" even thought I have generated a new certificate and is available under my KeyChain.
Even after I revoke all certificates, the number of certificates is still wrong.
Name: iOS Team Provisioning Profile: iOS Wildcard AppID
Type: Development
App ID: Xcode: iOS Wildcard AppID (*)
Certificates: 3 total
Devices: 10 total
Enabled Services: None
Expires: Mar 21, 2014
Status: Active (Managed by Xcode)
How can I bring this back?
Do I have to create a new one but it will no longer be managed? I have to add new devices/certificates manually next time?
you need to delete the Dev profile and create a new one then refresh it through organizer or download it and sync it with xcode.

The trick was to delete away everything and create a distribution profile and certificate.
Use the organizer to refresh and it will be created back.
If you still have your iOS Team profile listed as active in the online Dev Center provisioning portal, download it and double-click it. This will re-install it in XCode.
