Spritekit

This is your reference when building 2D games with SpriteKit on iOS. It covers the full stack: scene lifecycle and node hierarchy, SKAction sequences for animation, physics bodies with collision masks and contact detection, particle effects, camera control, and touch handling. The guide includes the frame cycle order (update, actions, physics, constraints), explains when to use different scale modes, and shows how to wire up SwiftUI integration with SpriteView. It's comprehensive without being exhaustive, hitting the practical patterns like texture animation, force versus impulse, and bit mask collision filtering. If you're moving from UIKit animations to a real game loop or need to remember how SKPhysicsContactDelegate works, this gets you there quickly.

Scene Setup

SpriteKit renders content through SKView, which presents an SKScene -- the root node of a tree that the framework animates and renders each frame.

Creating a Scene

Subclass SKScene and override lifecycle methods. The coordinate system origin is at the bottom-left by default.

import SpriteKit

final class GameScene: SKScene {
    override func didMove(to view: SKView) {
        backgroundColor = .darkGray
        physicsWorld.contactDelegate = self
        physicsBody = SKPhysicsBody(edgeLoopFrom: frame)
        setupNodes()
    }
