Hi! I am trying to make an app where you can start a timer when you start at work and stop the timer when you´re done at work and then it makes a list that you can export and it will say what days and times you have been working that month. So far I am having trouble with the timer. I want it to have this format 00.00 so if you have worked for 2 hours and 34 minutes it says 02.34/2.34. But it keeps going to 100 minutes before it will add a number to the “hour” position. Any ideas on how I could do this?

Here is the code I have so far:

import UIKit

class FirstViewController: UIViewController {

@IBOutlet weak var timecounter: UILabel!

var counter = 0.0
var timer = Timer()
var isPlaying = false

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    
    timecounter.text = String(counter)
}

@IBAction func StartDay(_ sender: Any) {
    
    if(isPlaying) {
        return
    }
    
    timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(UpdateTimer), userInfo: nil, repeats: true)
    isPlaying = true
    
}

@IBAction func EndDay(_ sender: Any) {
    
    timer.invalidate()
    isPlaying = false
    counter = 0.0
    timecounter.text = String(counter)
    
}


@objc func UpdateTimer() {
    counter = counter + 0.01
    timecounter.text = String(format: "%.2f", counter)
    if (counter == 0.10){
        counter = 1.00
        counter = counter + 0.01
        timecounter.text = String (format: "%.2f", counter)
        
    }
}

}

Thanks

what is this even?.. why 0.01?

you are not using correct “time” calculations/logic if thats the case

Thanks for your replay. I figured out a solution were I just added a second timer for the hour. So if any one else is wondering what I did here´s my code as for now:

import UIKit

class FirstViewController: UIViewController {

@IBOutlet weak var timecounter: UILabel!

@IBOutlet weak var hourcounter: UILabel!


var counter = 0
var counterh = 0
var timer = Timer()
var timerh = Timer()
var isPlaying = false

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    
    timecounter.text = String(format: "%02d", counter)
    hourcounter.text = String(format: "%02d", counterh)
}

@IBAction func StartDay(_ sender: Any) {
    
    if(isPlaying) {
        return
    }
    
    timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(UpdateTimer), userInfo: nil, repeats: true)
    
    timerh = Timer.scheduledTimer(timeInterval: 60, target: self, selector: #selector(UpdateTimer2), userInfo: nil, repeats: true)
    
    isPlaying = true
    
}

@IBAction func EndDay(_ sender: Any) {
    
    timer.invalidate()
    timerh.invalidate()
    isPlaying = false
    counter = 0
    counterh = 0
    timecounter.text = String(format: "%02d", counter)
    hourcounter.text = String(format: "%02d", counterh)
}

@objc func UpdateTimer() {
    counter = counter + 1
    timecounter.text = String(format: "%02d", counter)
    if (counter == 59) {
        counter = 0
    }
}

@objc func UpdateTimer2(){
    counterh = counterh + 1
    hourcounter.text = String(format: "%02d", counterh)
}

}
