Having UILabel update based on Audio Player current time - swift

Question

I am attempting to have my UILabel update based on the duration of what the AudioPlayer current time is. I don't want to use a timer, because within my app people will be recording themselves with small durations & the half seconds are important, so I wouldn't really want to use timer(). Instead what I am attempting to do is just have the label update based on what the current time is automatically. I can't however seem to figure it out...
Here is how I am going about it, but clearly I am not doing it correctly
var audioPlayer : AVAudioPlayer!
var audioTime = UILabel() {
didSet {
do {
try audioPlayer = AVAudioPlayer(contentsOf: audioURL!)
let currentTime = Int(audioPlayer.currentTime)
let minutes = currentTime/60
let seconds = currentTime - minutes * 60
audioTime.text = (NSString(format: "%02d:%02d", minutes,seconds) as String)
} catch {
}
}
}

This might help you! Connect Outlet to showTimeLbl and try.
class ViewController: UIViewController {
#IBOutlet weak var showTimeLbl: UILabel!
var timeCount:Int = 0
var timer:Timer!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
if(timer != nil)
{
timer.invalidate()
}
timer = Timer(timeInterval: 1.0, target: self, selector: #selector(ViewController.timerDidFire), userInfo: nil, repeats: true)
RunLoop.current.add(timer, forMode: RunLoopMode.commonModes)
}
func timerDidFire()
{
timeCount += 1
showTimeLbl.text = NSString(format: "%02d:%02d:%02d", timeCount/3600,(timeCount/60)%60,timeCount%60) as String
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(true)
timer?.invalidate()
timer = nil
}
