Unable to enable development on iOS 10.1.1

Maybe you forgot to register your device with your develop account? I got that error code (0x8000076) when I forgot to register it. To double check:

  • Find the identifier of your iPhone
    • In Xcode open the devices window (Window - Devices)
    • Select your phone and find its identifier
  • Login to your developer account (https://developer.apple.com/account)
  • Navigate to your devices (https://developer.apple.com/account/ios/device/)
  • Find the identifier in the list of devices.
  • Check if the names are identical

If it is missing, create a new entry.
