What will be displayed in example №8

In the example, two subclasses of the base controller are created, arrays of strings and objects are filled, and then one controller gets references to the arrays of the other. Then, the method to remove the last element from the string array is called. Determine which values will remain in the arrays after the code executes.

import Foundation

class MyView: CustomStringConvertible {
    let index: UInt
    var ID: String

    init(withIndex index: UInt) {
        self.index = index
        ID = String(index)
    }

    var description: String {
        return "(\(index), \(ID))"
    }
}

class MyViewController {
    var strings: [String] = []
    var views: [MyView] = []
}

class FirstViewController: MyViewController {}
class SecondViewController: MyViewController {}

let firstVC = FirstViewController()
firstVC.strings = ["One", "Two", "Three"]
firstVC.views = [MyView(withIndex: 1), MyView(withIndex: 2), MyView(withIndex: 3)]

let secondVC = SecondViewController()
secondVC.strings = firstVC.strings
secondVC.views = firstVC.views

secondVC.strings.popLast()
