Nit: You don't need the "2" on the variable name now that isn't in setExternalPlayback.

No need to protect "this"?

nil if that's a CALayer*

So much stuff.

Is this a GraphicsLayer::PlatformLayerID? If so, it needs to be 64-bit.

Blank line.

It is a PlatformLayer, which I guess is close enough in an Obj-c file. Change.

Sigh. Maybe a session object that cleans up all this implicitly in its destructor.

It is one of these:
uint32_t LayerHostingContext::contextID()
so it stays 32-bit.
