This document discusses animation basics in iOS development. It explains that animations can be added in viewWillAppear and viewDidAppear by modifying the frame, bounds, or center property of a view. Specific properties that can be animated are position, size, background color, and alpha. Different easing curves like curveEaseIn can be used to control the acceleration of animations.

coordinate system
▸ Frame
▸ Rectangle which describes the
views location and size in its
superview's coordinate system
▸ Center
▸ The center of the frame

VIEWDIDAPPEAR
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
UIView.animate(withDuration: 5,
delay: 0,
options: [],
animations: {
self.loginButton.center.x +=
self.view.bounds.width
},
completion: nil)
}

WHAT CAN WE ANIMATE?
▸ Position and Size
▸ Bounds
▸ Frame
▸ Center
▸ Appearance
▸ backgroundColor
▸ Change background color over time
▸ alpha
▸ Create fade in and fade out effects

ANIMATION EASING
▸ .curveEaseIn
▸ Applies acceleration to the start of your animation
▸ .curveEaseOut
▸ Applies acceleration to the end of your animation
▸ .curveEaseInOut
▸ Applies acceleration to the start and end of your
animation
