I'm learning Swift at the moment and came across "protocols". They seem to me like a prebuild class that you extend, like in typescript, is that true? Thanks, Pascal

CodePudding user response：

I would compare them to interface in typescript.

interface FooBar {
  foo: () => void
  bar: () => void
}

class MyFooBar implements FooBar {

   public foo(): void {
      ...
   }

   public bar(): void {
      ...
   }
   
}
