So far, you have seen animations that were implemented using the UIView.animate method. These animations are quite simple to implement and mostly follow the following format:
UIView.animate(withDuration: 1.5, animations:
{
myView.backgroundColor = UIColor.red()
})
You have already seen this method implemented in slightly more complex ways, including one that used a closure that was executed upon completion of the animation. For instance, when a user taps on one of the contacts in the Hello-Contacts app, the following code is used to animate a bounce effect:
UIView.animate(withDuration: 0.1, delay: 0, options: [.curveEaseOut], animations: { cell.contactImage.transform = CGAffineTransform(scaleX: ...
