What types of dispatching are implemented in this class?

In iOS development, two main types of dispatching are usually distinguished:
-
Static dispatching — when the method call is determined at compile time. This occurs when using regular methods and functions, where the compiler knows which specific method will be called.
-
Dynamic dispatching — when the method choice occurs at runtime. In Objective-C and Swift, this is implemented through the mechanism of dynamic method invocation (message dispatch), for example, when using protocols with default implementations, inheritance, and method overriding.
If a class uses, for example, method calls via objc_msgSend or method overriding, then dynamic dispatching is implemented. If calls are directly related to specific methods without polymorphism, then it is static dispatching.
Example of dynamic dispatching in Swift:
class Animal {
func sound() {
print("Some sound")
}
}
class Dog: Animal {
override func sound() {
print("Bark")
}
}
let animal: Animal = Dog()
animal.sound() // Will output "Bark" — a dynamic method call
