Steps to reproduce:
1) Open the attached project.
2) Open scene 'Test'.
3) Switch platform to 'tvOS'.
4) Press 'Play' in the Editor.

An error pops up in the Console:
MissingMethodException: Cannot find the requested method.

Any method from UnityEngine.Apple.TV.Remote class (for example, UnityEngine.Apple.TV.Remote.allowExitToHome) results in this error, even when used with #if UNITY_TVOS.
However, when the project is deployed to a tvOS device, this code works and functions properly.

Reproduced on:
5.5.0b1, 5.4.0p3

Did not reproduce:
