Question

Please provide the working source code in Swift macOS language. See the following instructions. Thank You

Description: Create and run an OSX Command Line application using Swift. Application specifics 1. In a separate file, define a class named Automobile 1. Define the following properties 1. Name:_make, Data type: string, Accessibility: private 2. Name:_model, Data type: string, Accessibility: private 3. Name:_numberOfDoors, Data type: integer, Accessibility: private 4. Name:_speed, Data type: integer, Accessibility: private 2. Define the following methods 1. An 'init method, with arguments for each property. Initialize all properties to their passed-in value 2. A class-level method named 'create', with arguments for each property. it's purpose is to create and return an instance of an Automobile object, using the passed in initial 3. Get and set instance methods for each private property, except the speed property, 4. A method named 'increaseSpeed', with one argument named 'speedChange' of 5. A method named decreaseSpeed', with one argument named 'speedChange' of type 6. A method named 'description' that will return the following string property values which should only have a get method integer type. Make sure the resulting speed is not outside the range of 0 to 150 integer. Make sure the resulting speed is not outside the range of 0 to 150 Make: , Model: won!!". Or, in the unusual event there is a tie, output "There was a tie!". The winner is determined by the greater speed 1. Example: Honda Accord won!! 3. 4. 2. At the global level, call the 'main' global-scope function The output should look like this, with speed values probably different when your program runs 3. Make: Maserati, Model: GranTurismo, NumDoors: 2, Speed: 67 Make: Honda, Model: Accord, NumDoors: 4, Speed: 128 Make: Tesla, Model: S 90, NumDoors: 2, Speed: 35 Honda Accord won!! 4. Build and run the app, and verify the output is correct. Random number generation code to include func randomValueBetween(min:UInt32, max:Ulnt32) ->UInt32 var randomValue:UInt32 = min + arc4random-uniform(UInt32(max-min + 1)) return random Value

Explanation / Answer

main.swift
-------------------------------------
import Foundation
func main() {
    // create 3 Automobile objects
    let a1 = Automobile.create(_make:"Maserati", _model:"GranTurismo", _numberOfDoors:2, _speed:0)
    let a2 = Automobile.create(_make:"Honda", _model:"Accord", _numberOfDoors:4, _speed:0)
    let a3 = Automobile.create(_make:"Tesla", _model:"S 90", _numberOfDoors:2, _speed:0)
  
    // randomValueBetween returns a random int between min, max
    func randomValueBetween(min:UInt32, max:UInt32) -> UInt32 {
        let randomValue:UInt32 = min + arc4random_uniform(UInt32(max - min + 1))
        return randomValue
    }
  
    // define a loop that iterates 10 times, calling the increaseSpeed method on each Automobile object
    for _ in 1...10 {
        a1.increaseSpeed(speedChange: Int(randomValueBetween(min: 0, max: 16)))
        a3.increaseSpeed(speedChange: Int(randomValueBetween(min: 0, max: 16)))
        a2.increaseSpeed(speedChange: Int(randomValueBetween(min: 0, max: 16)))
    }
  
    // call each object’s description method
    print(a1.description())
    print(a2.description())
    print(a3.description())
  
    // output results of race
    let winner = max(a1.speed, a2.speed, a3.speed)
    let speedSet:Set = [a1.speed, a2.speed, a3.speed]
    if speedSet.count < 3 && !speedSet.contains(winner) {
        print ("There was a tie!")
        exit(0)
    }
  
    if a1.speed == winner {
        print ("(a1.make) (a1.model) won!!")
    }
    if a2.speed == winner {
        print ("(a2.make) (a2.model) won!!")
    }
    if a3.speed == winner {
