My animation framework is now live! ✨. Introducing Motion, a SIMD-powered animation framework written purely in Swift, designed for making physically-modeled, gesturally-driven user interfaces, animations, and interactions. Let me know what you think :).

You'll also notice you can swipe down on your menu to collapse it and tuck it away to see and interact with the content beneath. All these interactions are powered by Motion ( and were in fact created using Adjustable.

Anytime a value is adjusted, it'll automatically invalidate the layout (or call ObservableObjects `objectWillChange`) to show your changes live. It also uses some super cool runtime tricks with Swift keypaths to automatically name each slider to match the value it's adjusting :).

Here's an example where I'm adjusting parameters with a CAReplicatorLayer. Normally it's tedious to tweak things across 50 build and run cycles, but now I can just set things how I want and update it in code.

This is perfect for adjusting interactions (e.g. springs) or layouts in real-time, so you can make apps feel great.

Introducing Adjustable!. Adjustable is a tool that I built to aid in adjusting values at runtime instead of constantly waiting for Xcode to rebuild after changing a constant. Add @Adjustable(0…1) to any property, and you'll automagically get a UISlider.

I created my own cover of Destiny 2's song "All That Matters". This is truly up there with one of my favourite songs in the Destiny franchise, so I couldn't resist learning and composing a stripped version. #Destiny2 #Destiny2MOTW #MOTW #DestinyTheGame

Craig just killing it on the guitar at @gruber’s Talk Show is the energy I’m here for

The Explore SwiftUI Animations talk is *fantastic*. Nice work @kylemacomber! . Thank you SwiftUI team for embracing Springs by default and making them so much more approachable for people! :D.

Drag Velocity!!.

Turns out, you can 😂

weeeee

Please ignore my terrible shader demo skills 😅.

It is *so* trivial to setup and experiment with Metal shaders now with SwiftUI!!! I'm loving this. No more needing to mess with contexts or anything, it's far more streamlined and automated. Now I *finally* have no excuses to practice and get good at writing shaders :D

Wow, Apple straight up introduced a raw analytical Spring function in SwiftUI. Even includes settlingDuration and a custom epsilon! . . First time I've ever had something I've written be "sherlocked", guess I should add Animatable support to Motion :D
