Discussion
In macOS, the default implementation of this method calls the preferredSizeOfLayer: method of its layout manager—that is, the object in its layout property. If that object does not exist or does not implement that method, this method returns the size of the layer’s current bounds rectangle mapped into the coordinate space of its superlayer.
