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
A screenshot of an Apple Developer webpage with the message “Access Unavailable” in bold. The text states that one or more apps have surpassed the 2 million first-time download limit, and PCC access is restricted to apps with fewer than 2 million total first-time downloads from the App Store. It notes that the limit is evaluated per app under the Apple Developer Program membership.

VirtualBuddy 2.2 beta 1 is out with support for automatic macOS account provisioning in macOS 27 🥳 #wwdc26 github.com/insidegui/Virtual…
Screenshot of a Virtual Machine Setup window showing configuration options. Skip Setup Assistant is enabled with options to automatically create a macOS account, log in automatically, and enable remote SSH login. Next to Skip Setup Assistant settings there's a button titled "Account Details"

A dark-themed virtual machine setup window shows a section for configuring a Mac user account. The pop-up form displays fields for Full Name set to “John Doe,” Username set to “johndoe,” and Password and Confirm Password fields filled with masked dots. At the bottom, there are two buttons: a gray “Cancel” button and an orange “Save” button. Behind it, part of the Boot Disk settings and Display configuration sliders are visible.

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. $ xcrun agent skills export --output-dir ~/Desktop/xcode-skills
Xcode 27's skill set.

Apple still sets the bar for software design. The way movies on Vision Pro reflect in the icy river of the new Iceland environment during the day, and how the snow softly glows at night, genuinely gives me goosebumps.

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 🥹 @stacktracepod

Since a recent firmware included components for a virtual iPhone, I decided to see if I could boot one up. This is a virtualized iPhone 16 running iOS 26.2. Don't get too excited, as this required a lot of IPSW patches and SpringBoard crashes when I swipe up in the setup screen.
