iOS Animations is definitely a hot topic. I have been into iOS development for 10+ years now and I have rarely seen any blog or post that serves as a definitive list of all resources for iOS animations. This blog post intends to compile all such resources online exhaustively.

Do share your inputs in the comments if you feel we have missed out on anything!

Open-Source Libraries

There are a ton of useful open-source libraries for iOS animation. Here are a couple I like:

WWDC – Advanced Animations – Designing Fluid Interfaces Animations

UIKit Dynamics – Explains UISnapBehaviour with Tinder card view example – Explains gravity with a ball falling to the ground and tinder’s snap behavior in detail

SceneKit–cms-23847 – Introduces the basics of creating a scene view, creating objects, placing materials and explaining the geometry involved.–cms-23877 – Provides high-level information about forming a scene, adding physics behavior like  gravitation, collision detection, animation

ARKit – Explains the very basics of laying out the foundation for creating ARKit apps by creating an ARKit scene view and placing objects in it – Explains the rendering of 3D objects, different formats of supported files by SceneKit for rendering 3D objects and online resources where we can create or buy/ sell these 3D objects – Explains the placement of horizontal surface/ planes in the real world and creates a sea and a fleet of ships on top of it – Explains the physics behaviors and animations through the example of launching a rocket ship

SpriteKit – Nice introduction and explanation about other entities of SpriteKit on a high level and  – Very basic tutorial about getting started with SpriteKit by placing a label and moving it across in an indefinite loop – Explains about using SpriteKit only for animations in apps on a high level with description of all entities

General – A Nice explanation about core animations on a high level – Explanation/ Suggestion on how to add subtle animations a.k.a reacting to user actions – A very basic article explaining CGAffineTransforms – Explains the recreation of Flipboard’s Flip animation using CoreAnimation framework APIs – Explains the usage of UIViewProperty for animations that provide interactivity & scrubbing – Explains the wrapper written to overcome code complexities – Explains about chaining UIView animations with RxSwift to avoid code cluttering. You can also find a nice in-depth introduction to RxSwift here. – A nice article explaining FPS, usage of instruments to measure FPS and other drawing/ animations stuff, how best to load images in a table view to avoid stutter (It is always better to draw images in a context since it offloads the image decompressing logic instead of directly assigning the image to the image view)
