extension Greeting {

class SimpleGreeting: Greeting { //No need to impliment the function
    
}

class WishesGreeting: Greeting {
    func sayHello() {
        print("Hello World this is new year")
    }

//Other way to create option protocol
@objc protocol ObjcGreeting {
  @objc optional func sayHello()
}


class ObjcSimpleGreeting: ObjcGreeting { //No need to impliment the function
    
}

class ObjcWishesGreeting: ObjcGreeting {
    func sayHello() {
