How to pass values from a Pop Up View Controller to the Previous View Controller?

Question

So In my 1stViewController I have this code:

@IBAction func colorDropdown(_ sender: Any) {
    self.popUpColorPicker()
}

func popUpColorPicker() {
    let popOv         


        

Answer 1

You can achieve this by either using delegate or completion handler.

Just create a delegate to handle your data on dismissing the second VC.

Write a completion handler closure to get back those values in your first view controller.
