What if you could let an yolo agent compile your Xcode projects without giving it the keys to your entire Mac?
That's xcbox (very pre-alpha): Apple container-based sandboxing for Xcode. No babysitting, no "my Mac exploded" vibes 😄

My attempt to protect users from scam apps on the @AppStore has gotten my Apple Developer account flagged for termination - ironically, for "dishonest activity".
Unless it's reversed by June 30, all new installs of Sparrow Wallet will fail, and development on macOS will end.
The context: since 2023, more than a dozen fake "Sparrow" apps have appeared on the App Store, as recently as April this year. Users have contacted me after losing their savings, in some cases their life savings, to these impersonators.
I'm the developer of the real Sparrow Wallet, a desktop app, and I hold the registered US trademarks for the name and logo. I have publicly warned @Apple and the community about these fake apps from early 2024, but they keep appearing.
The app @Apple flagged was a placeholder that was never published. Its only purpose was to warn users that Sparrow is desktop-only and that other "Sparrow" apps aren't mine. This approach may have been misguided, but there was nothing dishonest about it.
I'm confident this is an automated misclassification that Apple would reverse on review - but I may be terminated before a human ever looks at my appeal. The cost would fall on @Apple's own users: blocked installs and no updates for a tool people rely on, which opens the door for more fakes.
If you value Sparrow, a repost would help. @AppleSupport

@statusquont @bitcoinfool @Apple Didn’t work. App (with the screens below) was rejected for having “placeholder content” and only “demonstrating a concept”.

@VincentLoi1204 With the local model, yes. This is using server models.

@VincentLoi1204 It’s very finicky. I’ve only been able to make it work with the complete and structured guidance, any of the other configurations just doesn’t work for me either.

@_inside Awesome!!!
Are you using it with a provider (Claude or Gemini) or just FM?

So uh… Apple should really rethink the Private Cloud Compute developer access limitation. I do happen to have an app that’s had more than 2 million downloads. An app that’s been in the App Store for over 10 years. And I’m also not making any real money with it 🥲 #wwdc26

VirtualBuddy 2.2 beta 1 is out with support for automatic macOS account provisioning in macOS 27 🥳 #wwdc26 github.com/insidegui/Virt…

It's very cool that Apple shipped a 20B parameter on-device.
You can't put 20B parameters in RAM at any reasonable precision. To make it work they are using pretty exotic architecture by today's standards.
A small model predicts from the query (or prompt) which experts to load from Nand into RAM. The key distinction from a typical MoE is that you do this once per query and then generate all the tokens with the same experts (instead of switching the experts for every token).

Here are the skills that ship with Xcode 27.
Apple did a fantastic job with these (no surprise) from what I've poked around and looked at. Baseline SwiftUI guidance, and nuggets on how to use the new stuff like the reorderable APIs.

It’s so good to have Stacktrace by @johnsundell and @_inside back after two years.
Seeing it show up in my Overcast feed genuinely made my heart skip a beat.
I’ve honestly missed it quite a lot 🥹

@_inside interesting. now try it with real iOS, and not the modified private cloud compute image. like with my full Apple Silicon emulation project, Inferno, for example.

@newlooklurker @shitpost9000 @aboutzeph It’s both. The low-tech alternative would be for the watch to display a numeric code that the user has to type on their phone. Since the phone has a camera, you can use a QR Code, but a normal QR Code is not as cool as this 😄

@shitpost9000 @aboutzeph Is this a security thing or just because it looks cool
