Dynamic dispatch in Swift is a mechanism that allows the program to determine which function to call at runtime, rather than at compile time. This is essential for enabling polymorphism and other abstraction tools. In Swift, dynamic dispatch is used when a method is declared as a protocol requirement. If the method is declared in a protocol extension, it uses static dispatch instead. This distinction is important for both semantic reasons and performance optimization, as static dispatch allows for compile-time optimizations like inlining and generic specialization.
