SpriteKit

iOSmacOStvOSwatchOSvisionOS

SpriteKit is a 2D sprite-based game engine with Metal-backed rendering for iOS, macOS, tvOS, watchOS, and visionOS. You compose a scene from nodes such as SKLabelNode, SKEmitterNode, SKLightNode, SKAudioNode, and SKCameraNode, then animate and drive them with SKAction sequences and timing modes. Movement and collisions are handled by the physics system through SKPhysicsBody, SKPhysicsWorld, joints like SKPhysicsJointPin and SKPhysicsJointSpring, and contact reporting via SKPhysicsContact and SKPhysicsContactDelegate. You can further shape behavior with SKConstraint, force fields from SKFieldNode, masking with SKCropNode and SKEffectNode, and particle effects configured by SKKeyframeSequence.
