Question

import UIKit

override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
#IBAction func checkBoxTapped(_ sender:UIButton) {
UIView.animate(withDuration: 0.5, delay: 0.1, options: .curveLinear, animations: {
sender.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)
}) { (success) in
sender.isSelected = !sender.isSelected
UIView.animate(withDuration: 0.5, delay: 0.1, options: .curveLinear, animations: {
sender.transform = .identity
}, completion: nil)
}
}
}

Answer 1

I would have a method that does that.
func toggleCheckmark(_ checkmark: UIButton) {
if checkmark == self.checkmark1 {
self.selectCheckmark1()
self.deselectCheckmark2()
} else if checkmark == self.checkmark2 {
self.selectCheckmark2()
self.deselectCheckmark1()
}
}
Another option is something like this:
func toggleCheckmark(_ checkmark: UIButton) {
self.selectCheckmark(self.checkmark1, on: checkmark == self.checkmark1)
self.selectCheckmark(self.checkmark2, on: checkmark == self.checkmark2)
}

If you want to select any of the one option from the group, it better to use radio buttons instead of check boxes.
If not, we should do it manually. I did it in swift and its working
#objc func selector(_ sender: NSButton)
{
if sender == checkBox1
{
if sender.state == .on && checkBox2.state == .on
{
checkBox2.state = .off
}
}
if sender == checkBox2
{
if sender.state == .on && checkBox1.state == .on
{
checkBox1.state = .off
}
}
}
