What does internal dispatching of a method with a private access level mean?

Internal dispatching of a method with a private access level means that the call to this method is allowed and processed within a single module or class without the need for dynamic implementation determination at runtime. In Swift, for example, methods with private or fileprivate access levels are usually called directly (static dispatch), which improves performance because the compiler knows exactly which implementation to use and does not need to search for it in the inheritance hierarchy.

In other words, internal dispatching is a mechanism where the method call occurs without using dynamic polymorphism (for example, without virtual tables), as the method's scope is limited and does not allow overriding outside the current context.
