What types of dispatching are not modifiable through the Swizzling method?

Swizzling in iOS allows changing method implementations at runtime, but it only works with Objective-C dynamic dispatch. Types of dispatch that cannot be modified through Swizzling:

• Static dispatch (e.g., C or C++ function calls without virtual methods).
• Swift dispatch using statically resolved methods (e.g., final methods or struct methods).
• Method calls that are not implemented via the Objective-C runtime (e.g., methods not marked with @objc).

Therefore, Swizzling is only applicable to methods that go through the Objective-C runtime and does not work with purely Swift methods without @objc.
