Me, who never deleted a single .m file: I knew this day would come 😆
You know that moment when someone says "I asked ChatGPT" and the discussion just stops?
It's the new "works on my machine":

🏁 SwiftUI vs. UIKit 🏁
Build a native version of the chat screen in Campfire. One prompt, but this time with skills. SwiftUI got Apple's Xcode 27 skills, UIKit got ones I wrote.
Winner is UIKit 🥳 (2-0) vs. SwiftUI.
UIKit/Swift passed every test.
UIKit/Objective-C was the fastest and used half the memory 🏎️
SwiftUI is still slow (5s of stutters!), even with Xcode's swift-ui-specialist skill.
What would you like me to test for round 3? Code is in the repo (next comment).

The new GoodBarber back office puts your app at the center.
A Publish button that tracks your PWA, iOS and Android versions. Light, dark or system mode. Text size and contrast that follow you on every project.

👣 Qui a inspiré l'un des pères de l'IA ?
Dans ce livre on apprend que l'œuvre qui a le plus marqué Yann Le Cun est 2001, l'Odyssée de l'espace, conçue simultanément sous forme de film par Stanley Kubrick et de roman par Arthur C. Clarke.
Yann Le Cun, est un chercheur français qui a gagné le prix Turing, une sorte de prix Nobel de l'informatique. Il a aidé les ordinateurs à reconnaître des images. Grâce à lui, votre téléphone peut par exemple reconnaître un visage.
Dans « 2001 », il y a HAL, un ordinateur qui parle et réfléchit. Cette idée de science-fiction a donné envie à Yann Le Cun de la rendre réelle.
👉 Et vous, avez-vous vu le film ou lu le livre ?
Être cité par l'IA ne suffit plus, il faut se rendre disponible pour elle. Et sur le téléphone, l'assistant ne passe que par les apps installées.

Apps are the future, chapter 3.
Apple's new HomeView has no App Store of its own. Third-party audio and video apps come from your iPhone, and Siri takes action across apps.
New screen, same door: the app you already installed.
In September I wrote that our dev tools are built for humans, not for agents.
Anthropic just replaced git for exactly that reason 👀
They built Scion, their own source control, designed around agents that are always online.
New on our Engineering blog: Creating in-house source control.
In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale.
Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…
In 1986, one factory preset of the Yamaha DX7 was on 61% of R&B number ones.
It sounded great, then it dated every record that kept it.
The 2026 design look will probably go the same way.
Here's my new piece in @uxdesigncc:

Apps are the future, chapitre 2.
L'IA peut lire votre site à la place de vos lecteurs. Elle ne peut pas ouvrir votre app. Sites d'info -23 %, applis -9 % (ACPM).
L'app redevient essentielle en 2026.
AI Overviews : les sites d’info perdent 23% de visites, les applis résistent, selon l’ACPM.

Do all AI-generated apps look the same?
I measured it on seven models from three makers.
Within a category, yes: every model picks the same cliché. Navy and gold for the law firm, seven times out of seven.

Assistants are starting to use mobile apps without opening them. You ask Siri to move a booking, no screen appears.
So what's left to design there? Mostly words, and the rules around them.

We never left native at @GoodBarber. Went from old fashioned to early without changing a thing 😄
Start of a new trend and it’s once again Shopify being the trigger
I have to say as someone who used to develop mobile apps (iOS, Android, even Windows Phone) I have always had a soft spot for native: it’s the one where you are in control of your destiny. It used to require more work - AI reduces this

Do I need an app in 2026?
2010: yes.
2015: a website will do.
2026: yes again. Thank Siri and Gemini.

"You must stand behind every idea and sentence." Please stop sending me things you haven't read yourself!

Hum... are you sure we should stop treating them like humans?
(joke aside I am 100% in line with your take)
Stop treating AI like a human, an agent is not a colleague.
The problem isn't what we believe about the machine. It's what we hand it: pull requests, sprints, standups, all built for people.
