The fm CLI got a big upgrade in today's macOS 27.2 update! You now get easy access to AFM 3 Cloud running on Private Cloud Compute (in addition to the on-device LLM), right from the terminal. Zero setup!

I always wondered if Xcode could just build & run an app in a (virtualized) HomePod. It can!

‼️ BREAKING: Security firm Calif unveiled an untethered iPhone 18 Pro jailbreak on stage in Paris. Its Hexacon demo shows the phone on iOS 27.0.1, Apple's latest, giving up a root shell within 2 minutes of boot.

The simulator runtime for iOS 27.2 supports iPhone Duo now, but it still comes with almost none of the built-in apps. That doesn’t mean you can’t just install them from the non-Duo iOS 27.2 runtime via “xcrun simctl install” though 😏

I really wanted to see what the HomeView setup UI looks like on device, so I adapted my little ESP32 Apple accessory emulator firmware to broadcast its Bluetooth advertisements 😅

I've started looking into the new SwiftUI APIs for iPhone Duo in Xcode 27.1 and wrote a post on configuring toolbars, adapting custom labels, and prioritizing toolbar actions or tabs when space is limited: nilcoalescing.com/blog/Confi…

Xcode 27.2 also ships a tool for .xcproj: xcprojformatter Not just a pretty-printer: it parses the project into a model and writes it back in canonical form. Unknown keys get dropped, broken JSON fails with the exact path to the error. Handy for pre-commit, CI and checking agent edits

iOS users in the EU, you can finally control your iPhone on the Mac!
Readers added context they thought people might want to know
Poster is talking about an app called Device Hub that’s part of the Xcode suite. iPhone Mirroring still isn’t available in the EU. developer.apple.com/documentation/… support.apple.com/en-my/120421

SwiftUI isn’t native and here’s why SwiftUI apps may sometimes feel janky. It ditches the key element that made animations run so smoothly on iOS since the original iPhone: Core Animation. In SwiftUI animations run in-app without CA backing. Block the main thread: SwiftUI ball stalls while UIKit’s keeps moving on the render server.

Homebrew 7.0 is out. Also got the UI!
Today, I’m proud to announce Homebrew 7.0.0. The most significant changes since 6.0.0 are faster installations, stronger sandboxing, native macOS app, vulnerability checks, advisory database, end of macOS 10.15 support and Intel Macs to Tier 3. brew.sh/2026/09/13/homebrew-…
