Requires Xcode and the Facebook pop library, pop can be added via CocoaPods.

In plain English

Popping is a collection of animation examples built for iOS apps. Almost all of the animations in it use the Facebook pop animation engine, which is a physics-based animation library for iOS. The project is meant to give developers a set of visual references and starting points for building polished, lively user interfaces. To use it, you clone or download the repository, build it with Xcode, and run it on a simulator or device. You can then browse through the included animation examples and experiment with them directly. The README links to a video showing all the animations in motion, including a folding animation that was added after the initial release. The project is written in Objective-C, the older of the two main languages used to write iOS apps (the newer one being Swift). The README is short and does not describe the individual animations in detail, but directs you to watch the video for a full overview. The author also mentions a willingness to package specific animation classes as a CocoaPod, which is a standard way to share reusable iOS code, if there is interest.

Copy-paste prompts

Prompt 1

Show me how to use the Facebook pop animation library in Objective-C to add a spring bounce effect to a UIView when it appears on screen.

Prompt 2

I want to add a folding animation to a card view in my iOS app. Show me how to implement it using Objective-C and the pop animation library, like in the Popping examples.

Prompt 3

How do I add the pop animation library to my Xcode project using CocoaPods and trigger a physics-based animation on a button tap?

Prompt 4

I cloned the Popping repo. Walk me through what I need to do in Xcode to build it and run the animation demo on a simulator.

Prompt 5

I'm using the pop library for an iOS animation. How do I tweak the spring bounciness and speed values to make a UIView feel more snappy?
