Protocal and delegates⌗

Protocal can assign some function to classes while classes dont need to know the func specifically only when the class is assigned delegate

protocal AdvancedLifeSupport{
    func performCPR()
}

// any class has the delegate AdvancedLifeSupport has the method performCPR()


struct Paramedic: AdvancedLifeSupport {
    init(handler:EmergencyCallHandler){
        handler.delegate = self
    }

    func performCPR() {
        print("The paramedic does chest compressions, 30 per second.")
    }
}
// struct can have func method from delegate
// class can as well
