Change the value of an element in a PFUser Object of type Array, in Swift

Question

I'm new to Parse server. First, I create a multidimensional array as an object on Parse server

let day1 = ["one", "two", "three", "four"]
let day2 = ["five", "six", "seven", "eight"]

let jan = [day1, day2]
let feb = [day1, day2]

let calendar = [jan, feb]

let user = PFUser()
user.username = userNameTextField.text
user.password = passwordTextField.text
user["Calendar"] = calendar

What I want is to be able to do a PFUser query and change the value of calendar [ 1 ] [ 0 ] [ 1 ] from "two" to "zero". I've gone over Parse's documentation, but I'm just confused on how I could accomplish this. Thank you for your help!

Here's the code that accomplishes what I was trying to do:

@IBOutlet weak var bedTimeTextField: UITextField!

    var userCalendar = PFUser.current()?.object(forKey: "Calendar") as! Array<Array<Array<Any>>>

    func setBedTime(int: Int) {

        userCalendar[1][1][int] = 0

        PFUser.current()?.setValue(userCalendar, forKey: "Calendar")

        PFUser.current()?.saveInBackground()

    }

    @IBAction func cmonButton(_ sender: Any) {

        if bedTimeTextField.text != "" {

            let textFieldInt: Int? = Int(bedTimeTextField.text!)

            setBedTime(int: textFieldInt!)

            let userCalendar = PFUser.current()?.object(forKey: "Calendar") as! Array<Array<Array<Any>>>

            print(userCalendar)

        }
