ERROR Internal navigation rejected - <allow-navigation> not set for url='gap://ready'

When running an ionic 3 project on an IOS device with XCode, i get this message and the application hangs on a blank screen after the splash page: ERROR Internal navigation rejected - not set for url=‘gap://ready’. I can’t get past this, have tried many things. Has anyone else had this problem? Any suggestions?

Any luck with this? We are facing the same problem.
