I'm trying to build an Ionic-cordova app in Xcode. It is throwing following error.

libc++abi.dylib: terminating with uncaught exception of type NSException

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIApplication 0x7ffd2b7053a0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key view.'
