Subclassing Scenes Versus Assigning a Delegate

Use a scene delegate to share app logic across various scenes.


Often, your app subclasses SKScene to deliver gameplay. Your subclass usually:

An alternative pattern is to assign a delegate that handles Responding to Frame-Cycle Events instead. For example, if you make the view controller the delegate for your scene, it can use multiple scenes that share the same SKSceneDelegate implementations. The view controller participates in event handling and so it can respond to user input also.

Important: On macOS, you need to set the window’s nextResponder to your app’s view controller because by default, the view is the first responder to user input events
