Access Control(訪問控制)
Swift有三種訪問控制：
- Public: for code called by the app or other frameworks, e.g., a custom view.
- Internal: for code used between functions and classes within the framework, e.g., custom layers in that view.
- Private: for code used within a single file, e.g., a helper function that computer layout height.

In the Identity Inspector, under Custom Class, change the Module to ThreeRingControl.
