UE5 for iOS on Sample Project

I have the ContentExamples Sample project and trying to build and run on iOS on device in Quick Launch. i have added the certificates and profiles and set the bundle identifier etc, that is all ok.
When I try to quick Launch it, I am erroring out with:
error: ERROR: Unhandled exception: System.Exception: Couldn’t find AdditionalSearchPath for rules source files ‘/Users/[myusername]/Downloads/Unreal/ContentExamples/Platforms’

Any ideas? Seems extremely frustrating that the basic samples don’t run.

Cheers!
