Question

Swift code

import Foundation

protocol TaksPerformer {

func doAThing()

}

class Employee: TaksPerformer {

let name: String

var boss: Boss?

init(name: String) {

self.name = name

}

func doAThing() {

print("\(name) is doing a thing")

}

}

class Boss {

var employee: Employee

let name: String

init(name: String, employee: Employee) {

self.name = name

self.employee = employee

employee.boss = self

}

func actLikeABoss() {

employee.doAThing()

}

}

// 1)

// A) What is wrong with the current implementation of Boss and Employee, why is it wrong, and how can we demonstrate that there is an issue?

//

// B) What pattern discussed in class does the Boss - Employee relationship remind you of? Give an example of the discussed pattern.

//

// C) Create a Person class that has the following property:

// let name: String

// Now have Employee and Boss inherit from Person

//

// D) You realize that there are speciffic tasks you would like an employee to perform. All tasks look like this:

// func makeCoffe(_ name: String) {

// print("\(name) made coffe")

// }

//

// func writeReport(_ name: String) {

// print("\(name) wrote a report")

// }

// Modify Boss, Employee and TaskPerformer in a way that a Boss can be instantiated with the following constructor:

// Boss(name: "Bossman", employee: anEmployee, tasks: [makeCoffe, writeReport])

// The employee instance should perform the tasks.
