Bubble button animation demo iOS app

This demo app shows how to apply spring style animation to a button.

Animation is done by setting Scale transform to the button inside animation block. This demo app allows to tweak duration, damping and velocity parameters of the animation function.

button.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)

UIView.animate(withDuration: 2.0,
  delay: 0,
  usingSpringWithDamping: 0.2,
  initialSpringVelocity: 6.0,
  options: .allowUserInteraction,
  animations: { [weak self] in
    self?.button.transform = .identity
  },
  completion: nil)
