Enables an entity to be used withing the defining module (target). You typically use internal access when defining an app’s or a framework’s internal structure.

Enables an entity to be used within the defining module (target). You typically use internal access when defining an app’s or a framework’s internal structure.

• open classes and class members can be subclassed and overridden both within and outside the defining module (target).
• public classes and class members can only be subclassed and overridden within the defining module (target).
