Sporadic registrations on iOS using Xcode

[arcm1138]

Expected Behaviour

Consistent device registration

Actual Behaviour

When running / installing on a test device, it only registers the device sometimes and then stops working completely. This is with no settings changing (Light UI / CSS work only).

To get it registering again, I have to..

1> Remove the Push capability
2> Clean the build
3> Run the app, (push error thrown)
4> Close Xcode
5> Delete the app from the phone
6> Restart the phone
7> Restart Xcode
8> Re-enable the Push capability
9> Clean the build
10> Run / install

Sometimes this fixes the issue. Other times I have to continue to mess with the above process.

I submitted a build to Apple after getting it to work locally, but it didn't register for them.

Any suggestions welcome, thanks.
