Set max value on UIProgressView (swift 4)

Question

My code below has no limits and eventually goes to the end of the progress view without stopping.

I would like the progress view to go to the end of the bar within 10 seconds in 1 second intervals.

import UIKit

class ViewController: UIViewController {

    @IBOutlet var progessV : UIProgressView!
    var progressValue : Float = 0

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        Timer.scheduledTimer(timeInterval: 0.01, target: self, selector: #selector(update), userInfo: nil, repeats: true)
    }

    @objc func update(){
        progressValue += 0.01
        progessV.progress = progressValue

    }
    @IBAction func reset() {
        progressValue = 0
    }

}

You must set the timer to 1s and add it to a variable to stop it when it arrives to ten seconds.

Your code become to something like this:

import UIKit

class ViewController: UIViewController {

@IBOutlet var progessV : UIProgressView!
var progressValue : Float = 0
var timer : Timer?

override func viewDidLoad() {
    super.viewDidLoad()
    timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(update), userInfo: nil, repeats: true)
}

@objc func update(){
    if (progressValue < 1)
    {
        progressValue += 0.1
        progessV.progress = progressValue
    }
    else
    {
        timer?.invalidate()
        timer = nil
    }
}
@IBAction func reset() {
    progressValue = 0
}
}
