My agent said it had added the contact.
It was describing the simulator, not looking at it.
agent-device by Callstack lets coding agents actually open, tap and fill an iOS or Android app, then save evidence.

You still need a booted simulator or device and a running app. React DevTools / CDP features want a development build, and Expo Go only profiles the host process. It is not a replacement for Xcode breakpoints when you need to step native code.

Designer: "When you tap the photo, can it sort of fly into the next screen?"
Me, three GitHub issues deep: "Define fly."
Reanimated 4.7 from @swmansion makes the new layout engine the default, and that's the one shared element transitions run on.

➡️ New layout engine on by default
➡️ More shared element fixes
➡️ Animated gradients via backgroundImage
Shared elements are still experimental, and grab 4.7.1.

It's business accounts only for now, and Callstack admit frontier models still win on general knowledge. Try it on a few of your own tickets before you trust a benchmark.

Cheaper models that hold up on real work come up a lot in The Agentic Rewind, and Apex was a lead story in issue #1 👇

iPhone Duo pre-orders open tomorrow, so somewhere a PM is writing a ticket called "fold support (small)".
react-native-arrangement-view by @thiagobrez splits your screen into two panes either side of the hinge on iOS and Android.

My agent told me it had fixed the layout bug.
It hadn't opened the simulator once.
Mobile Dev for Codex by @lauridskern and Hanno Gödecke puts your iOS simulator and Android emulator next to the chat.

It's an early preview for the Codex desktop app on Apple Silicon Macs, and iOS needs Xcode 26 or later.
