A Swift library providing enhanced easing equations and tweening capabilities for SpriteKit animations.
SpriteKitEasingSwift is a Swift library that enhances SpriteKit with advanced easing equations for smoother, more expressive animations in 2D games and interactive apps. It solves the limitation of SpriteKit's basic easing options by providing a wide range of timing curves (like Elastic, Bounce) as easy-to-use SKActions. Developers can tween node properties or custom variables to create professional motion effects.
iOS and macOS developers building games or interactive applications with SpriteKit who need more control over animation timing and motion curves than SpriteKit's built-in easing provides.
It offers a straightforward, Swift-native API that integrates seamlessly with SpriteKit, saving developers from implementing complex easing math themselves. As an open-source port of a proven Objective-C library, it provides reliable, production-ready animation tools with minimal overhead.
Better Easing for SpriteKit in Swift

Provides a comprehensive set of easing equations like Elastic and Bounce, which are not natively available in SpriteKit, as shown in the easing.gif and code examples for natural motion effects.
Returns SKAction objects that work directly with SpriteKit's animation system, allowing easy implementation without disrupting existing workflows, as demonstrated in the move and fade tweening methods.
Includes createFloatTween and createColorTween methods for animating custom properties, offering fine control beyond standard node animations, as outlined in the README.
As a port from Objective-C to Swift, it offers a modern, type-safe API that aligns with current iOS/macOS development practices, making it accessible for Swift developers.
Only useful for SpriteKit-based projects, rendering it irrelevant for developers using other Apple frameworks like SwiftUI or UIKit, or non-Apple game engines.
Relies on Travis CI which is deprecated, and the project has not seen recent updates, risking compatibility issues with newer Swift versions and Xcode tools.
The README covers basics but lacks in-depth tutorials or API documentation, which could hinder debugging or implementation of complex animation scenarios.
