A Swift library that simplifies iOS animations with pre-built effects, storyboard integration, and easy chaining.
Spring is an iOS animation library written in Swift that provides a simplified API for creating smooth, customizable animations. It offers a collection of pre-built animation effects that can be applied through both code and Interface Builder, reducing the boilerplate typically required with Core Animation. The library solves the problem of complex animation implementation by providing ready-to-use animations with easy property configuration.
iOS developers working with Swift who want to add polished animations to their applications without dealing with the complexity of Core Animation APIs. Particularly useful for developers who prefer visual configuration through Storyboards alongside programmatic control.
Developers choose Spring because it dramatically reduces the code needed for animations while providing a rich set of pre-built effects. Its unique integration with Interface Builder allows visual designers to configure animations, and the simple chaining API makes complex animation sequences straightforward to implement.
A library to simplify iOS animations in Swift.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Includes over 20 ready-to-use animations like shake and pop, reducing the code needed for common effects compared to raw Core Animation.
Allows visual configuration of animation properties in Interface Builder's Attribute Inspector, enabling designers to set up animations without coding.
Supports sequencing animations with methods like animateNext, making it straightforward to create complex animation flows with minimal code.
Offers control over properties such as force, duration, and damping, providing flexibility to fine-tune animation behavior for different use cases.
Not all animation properties work together effectively, requiring trial and error with the demo app to achieve desired combinations, as noted in the README.
Autostart animations fail when views are accessed via performSegueWithIdentifier, a known issue that can disrupt user navigation and require manual workarounds.
Requires Xcode 10 and Swift 4.2, tying it to older toolchains and making it less suitable for projects on newer Swift versions or needing frequent updates.
