Dynamic Dispatch

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 in the main body of a protocol, making it a protocol requirement. Conversely, if a method is declared in a protocol extension, it uses static dispatch, which is more efficient because it allows for compile-time optimizations like inlining and generic specialization.
