Is there a reason you removed this #ifdef? I don't think we generally set the layers' names in release builds.

And I think this may need a #ifdef as well.

You said this wasn't necessary in MediaPlayerPrivateMediaStreamAVFObjC::createPreviewLayers().  Is it necessary here?

Is there a reason why this entire file shouldn't be wrapped this way?  Also, I think that you may want PLATFORM(COCOA) here.

Simon says (see what I did there?) it is fine to set layer names in a release build as long as the name doesn't have to be computed.

Ditto.

Because this layer is set as a sub-layer of the layer returned by MediaPlayerPrivateMediaStreamAVFObjC.

Oops!
