does it have to be a key path to an optional property of
CameraOptions
? I see that CameraOptions has everything as Optional now, but if in the future we decide to add new property that is non-optional then this will not work for those properties.There was a problem hiding this comment.

It wouldn't have to be. Doing it this way allows
value
(on the next line) to be non-optional.The
*Options
naming pattern in GL Native typically indicates a type where all of its fields are optional. You pass instances to a setter and non-nil fields are updated and any nil fields are not modified. Given that, it's probably unlikely that we'll add non-optional fields toCameraOptions
in the future.
