I have setup a new nativescript app by running the following:-
tns create application --ng
When I attempt to launch the application using:-
tns run ios --emulator
I get the following error:-
Unable to apply changes on device: BC7714A3-A8B0-4CEC-A7A4-D54563CF04EE. Error is: Command xcodebuild failed with exit code null.
The full error is:-

Executing after-watch hook from /XXXXXX/Desktop/Bike/hooks/after-watch/nativescript-dev-typescript.js
The application occasionally launches without an issue, but stops 95% of the time I get the error above.
Any help would be greatly appreciated.
