Exploring SpriteKit
SpriteKit is mostly used by developers to build two-dimensional games. SpriteKit has been around for quite some time already, and it has helped developers to create many successful games over the years. SpriteKit contains a full-blown physics simulation engine, and it can render many sprites at a time. A spriterepresents a graphic in a game. A sprite could be an image for the player, but also a coin, an enemy, or even the floor that a player walks on. When sprites are mentioned in the context of SpriteKit, it is meant to refer to one of the nodes that are visible on the screen.
Because SpriteKit has a built-in physics engine, it can detect collisions between objects, apply forces to them, and more. This is pretty similar to what UIKit Dynamics is capable of. If you're a bit rusty on what UIKit Dynamics are and how they work, be sure to have a look at Chapter 4, Immersing Your Users with Animation for a refresher.
To render content, SpriteKit uses scenes. These scenes can...
