I'm joining @OpenAI at the end of the month, and I can't wait to get started!
I'll be working on everything related to Codex, bringing what I learned building Codex Monitor, and working with the developer experience team with @romainhuet!

It's Nintendo; it'll probably last forever if you're not actively trying to detonate it.

Completely insane. They’re literally robbing Apple in daylight. They’ll be completely integrated with macOS in a much better way that Apple will ever do. And will probably give them a good head start for building their own OS.
We’ve acquired Software Applications Incorporated, the maker of Sky—a natural language interface for Mac.

BTW, I've switched to Cursor entirely for iOS development, and @rudrank blog is full of everything you need. rudrank.com/tag/cursor/

I don’t think this UI will survive until the final release 😂. I love it but it’s so out of this world.

I can’t believe Apple will ship the phone app like this. What the actual point? Where is the courage.

So the VSCode Swift extension is now officially supported by Apple. Is this the end of Xcode for real?

I have 3DS, DS, GB, GBC and cartridges behind me on my shelf and they all play fine. The only thing dying is the battery in some GB/GBC carts.

It's a shit-tier product with a bad UX and an expensive subscription to buy average images. Sadly, it makes me believe that when you become famous in one field, everything else feels granted & easy for you. Well, it's not, and I hope he realises it.

I’m drinking the Flutter tears lol. Who the F thought it was a good idea to re implement the whole iOS visual language lol? And now they need to do it again.

#SwiftUI NavigationStack is really revolutionary because it allow you to have a clean / proper router without any shenanigan.

The fact that my entire Form user interface in SwiftUI is only 40 lines of code long is a total madness. The Picker API in Form save soooooo many of what would have been UIKit glue code.

Let's break it down. This time, I started with an empty Xcode project. Claude 4 one-shotted a fully working iOS app that can list and create posts (with a good UX) and read/write to a database. It compiled the app and took a screenshot to confirm that it's working. One prompt.

I know people from @AnthropicAI follow me, and they've been chatty before. The fact that no one is talking is quite revealing IMO. It smells like some big (known or unknown) problems inside.

I wish I had more complicated code to show, but this is our UI code these days. It's as vanilla as it can get because why make things complicated when it's simple.

Oh my god! You can now detect when a view get outside or inside the viewport of a ScrollView! And this is precisely the usecase I need.

So I'm finally 99% done with the discover part of MovieSwiftUI. Filtering works, I even have two .presentation() modals with success! All the code available here. Form, Gesture, animations and more! github.com/Dimillian/MovieSw…

If you want to see how polarised the iOS community is, I just need to post this.

Whoa, my dude you're selling React Native. Of course, you have that stance. I can spot RN apps from 100000 miles away. It's like iOS app from Wish.
I read this tweet and laughed. We regularly come into companies that have full, dedicated native app teams, rebuild their entire (10+ year old) apps in React Native, and pass up their native teams who are still struggling to ship features. Then ship to the App Store / Google Play Store and improve the overall star rating for the apps.
(The *best* possible outcome is when the native devs enthusiastically embrace React Native ... because they tend to make amazing RN devs. I was a native iOS dev prior to RN!)
I get that my team is particularly good at RN, but if your team is going to slow down their feature iteration speed and destroy their app quality just because they switch to React Native, it's really not the tech stack's fault.

How it’s possible that no one is talking about this? This is the single best new feature of UIKit ever. It’s been such a pain to resize individual cells on the fly omg.

This is a really, really nice UI. The OpenAI team is really on top of their game. I actually often forgot about the macOS app and use the web UI more often. But the new apps integrations is quite good for a quick chat. I'll use it more.

Let me show you the power of Claude Code agents with a SwiftUI example.
1. The output of the default/generatlist Claude Code agent
2. The output with a custom SwiftUI architect agent

To be fair there is some very nice volumetric effect that make everything very readable on beta 3.

Okay here is the sad news:
- RIP Claude Code for now, idk if @AnthropicAI really recovered from their inference issue, but even Opus became lazy.
- Cursor Agent CLI with GPT-5 is really, really good with carefully crafted prompts.

There is a cool trick in SwiftUI if you want to add views to your navigation bar. You can use safeAreaInset(.top) and decide whether to remove the divider and merge the background or not using toolbarBackground visibility modifier.

I don't think people understand how good iPadOS 26 is or how well we have it with the SwiftUI API. TabView is now the API you want to use for your root container. It adapts almost perfectly to any window size. And it's easier than ever to make adaptable apps.

Ur finger is over it’s glowing under OMG
I’ve talked a lot on here recently about how the old glow behavior with Liquid Glass made no sense when Apple still has many SDR displays in their lineups. This is what I was talking about: very annoying and difficult or impossible to read. Recorded on my iPad mini.

I plan to release it in september. Yeah all SwiftUI, I want to see how far I can go without UIKit at all.

Little demo of a small app with xtool, do you understand how fast it is? It takes less than a second to build and install on the simulator. It opens so many opportunities!

We're definitely entering a new age of native iOS engineering. This is so much more flexible than stupid UI and rigid UI testing scripts. Next I'll try to build a new feature and tell the agent to build and run until it's working good.

Twitter did not change the like animation. Such wrong claims are often spread to trick people into clicking the like button
