If the truth actually backs up what you say about me and why I was fired, let's make everything public and let people judge for themselves. You are the CTO of Meta, a trillion dollar corporation. This is fully within your power, not some peon decision. Just say the word.

She’s being very modest, the truth is, this is most people. The difference is, Scarlett’s introspective enough to notice social media affects her mental health, and wise enough not to touch it, despite everyone around her using it.

How the fuck did @theapplehub fail to mention @Apple‘s expected to announce their #Xcode #AI coding tool to finally rival Copilot? It’s gonna be the biggest news at #WWDC24.

Glad to hear Apple is finally getting onboard with code gen tools. Combined with Xcode String Catalogs, we could be less than six months away from having auto-localized apps. The next five years, while devs still have jobs, are going to be exciting!

One tool I use on the reg to keep my apps #accessible is the Color Contrast Calculator in the #Xcode Accessibility Inspector, which not only tells you if your color theme is accessible, but even offers color suggestions. Surprised how hidden @Apple makes this tool for devs to use

You'll see a lot of 3D solutions to problems that are already solved really well in 2D apps on the phone (e.g. 3D location apps). This will change as scene-understanding improves with #AI, and form factors continue to shrink, but that's not tomorrow.

After playing with #SwiftData all day, I've decided to rip it out of my throwaway #iOS dating app, and use #CoreData. It's close to amazing, but what it lacks makes it unusable in a testable, real-world app. I was surprised to find it has no NSFetchedResultsController equivalent.

My first impressions of #SwiftData are mixed. It's magical how quickly you can persist complex model data in your app, until you try to use it in a real-world #TDD scenario, and use it in a view dependency, at which point it loses it's magical powers, and is a nightmare to use.

I'm building a throwaway dating app to play with #Swift Macros, #SwiftData, and #TCA. It's wild how much the ergonomics of a modern #iOS codebase have changed over just the last three years.

The biggest mistake I see novice #SwiftUI devs facing is not spending time understanding the concepts of Layout Neutrality and View Identity, leading to excessive use of fixed frames and if-else statements, resulting in performance issues, faulty state, and broken animations.

If any of the Apple platform devs that follow me are recently taking an interest in XR tech now that Apple has entered the market, here’s the most down-to-earth summary of the current VR industry you’re lucky to get. I recommend following Denny if you plan to dev on #visionOS

A #visionOS question I’m often asked is whether to use the native tools (Reality Composer Pro/RealityKit/ARkit) or #Unity. I’m proficient with both, so in most cases, I lean towards Unity for any 3D/XR app development. 💯 if it’s a cross-platform app. Some general reasons why:…

We always joked that the hardest aspect of AR development is figuring out what to use it for. Limited scene understanding has been the biggest limiter to useful AR applications. Crazy to see that we already have the AI tech to do deep scene analysis, we’re just not yet using it.

There has never been a more awkward time to be an #iOSDev. I’m currently overseeing the development of 1) a hybrid Objective-C/Swift/UIKit app, 2) a #Swift/#SwiftUI app, and 3) a #Unity/C#/#visionOS app. All targeting the same ecosystem and it feels like 3 different careers 😂

Do you understand the functional/performance implications of using the "return" keyword in this #SwiftUI view? Omitting "return" uses SwiftUI's conditional view builder, which returns a single view type, satisfying the "some view" constraint, but it takes a performance hit.

Ever wonder why #SwiftUI uses the "some" keyword instead of the "any" keyword? The answer is performance. SwiftUI works by comparing two trees when @State changes. Comparing trees is incredibly expensive, except for when trees have the same structure. "some" enforces structure.

Note to #visionOS native devs, if you grab the Xcode 15 RC, be sure to keep any beta version(s) of Xcode 15 installed, since #visionOS is no longer a build target in the RC (since visionOS is still in beta). #swift #iosdev #xcode

With tools like #Unity & #RealityKit, building 3D apps no longer requires a PhD in 3D Graphics, but for #iOS devs, it introduces entirely new concepts. Here are tips for excelling as a #visionOS developer (beyond just adding static 3D models to your existing #SwiftUI apps) 🧵

#visionOS Scene type cheetsheet: Window - 2D, bounded, movable, resizable, shares space with other apps Volume - 3D, bounded, movable, fixed size, shares space with other apps Immersive Space - 3D, unbounded, fixed position with origin at user's feet, app takes over full space
