Hiding UIButton if variable has certain value? - ios

Question

I want to hide a UIButton as long as a certain variable has not reached a certain value.
I tried some setHidden and isHidden setups, but I guess I did it all wrong. I don't exactly know where to put these commands.
I have looked for a solution at almost every webpage but I got no idea what everybody is talking about.
import UIKit
class ViewController: UIViewController {
let startvalue = 1000000
#IBOutlet weak var Counter: UITextField!
#IBAction func Button(_ sender: UIButton) {
if number > 1{
number -= 1
Counter.text = String(number)
} else {
Counter.text = "Hurray"
}
}
#IBOutlet weak var Reset: UIButton!
#IBAction func Reset(_ sender: UIButton) {
if number == 1{
number = startvalue
Counter.text = String (number)
}
}
override func viewDidLoad() {
var number = startvalue {
didSet {
if number < 1 {
Reset.isHidden = false
}
}
}
super.viewDidLoad()
}
}
I don't now what I need to put where to hide Result as long as number is greater than 1.

Handle it in the didSet of the variable.
var number = startValue {
didSet {
if number < 1 {
yourButton.isHidden = false
}
}
}
Now, whenever your number is changed, the didSet block will check if the value is less than 1. If so, it'll unhide the button.
Note: Make sure the button is hidden before the view shows. Also, make sure to hide the button if needed on resetting.
Use lowerCamelCase for variable names like they say in the API design guidelines.
