You don't need 3rd party code if you target your app to iOS 14. It has the UIColorPickerViewController and it's quite straightforward.

let picker = UIColorPickerViewController()
picker.delegate = self
present(picker, animated: true, completion: nil)

You can set the intitial selectedColor, or change supportsAlpha to false to hide the alpha slider and only allow opaque colors.
