Antoine van der Lee benchmarked Xcode 27's new MCP against RocketSim's CLI and found a 7x difference in token consumption. If you're using AI agents to navigate iOS Simulators, this could be quietly draining yo...
Netflix just solved a problem every mobile team faces: how do you turn cinematic 16:9 video into vertical formats without losing the story? Their answer involves neural networks, active speaker detection, and a...
Krystof Woldrich from Expo just solved the chaos that hit mobile devs when Xcode 27 killed Simulator.app. If you spent "Xcode 27 week" manually booting simulators and losing fast refresh, this one's for you.
Bartek Krasoń and Mateusz Turbański from Software Mansion tackle one of mobile's trickiest UX problems: getting users to the right screen after they install your app from a link. Their solution using Detour eli...
Antoine van der Lee reveals how SwiftUI performance problems hide in plain sight. Most developers know views redraw too often, but measuring the actual cost requires knowing exactly where to look in Instruments...
Amorn Apichattanakul built a 3D hotel tour in Flutter and discovered the hard truth: one demo ran at 120fps, the other barely hit 25fps. Here's what actually works for 3D in production apps.
Antoine van der Lee built his Video Compressor app with AI agents that can actually see and measure what they're building. His accessibility score jumped from 0/100 to 99/100 without manual testing.
Darin Wilson from Infinite Red reveals how Expo just eliminated the biggest barrier to adopting React Native: you can now integrate it into existing native apps without a rewrite, and it takes just five words t...
Katarzyna Smoleń from Software Mansion breaks down a critical iOS testing decision: BrowserStack isn't always the right fit, especially if you're running AI agents or need dedicated simulator infrastructure.
Antoine van der Lee just launched RocketTrace, a Mac app that makes AI agents 6x more efficient at finding iOS performance issues. The benchmark results are striking: agents found more bugs while using a fracti...
Anton Makeev from JetBrains just announced they're pulling Swift IDE support from the Kotlin Multiplatform plugin. If you're building cross-platform apps, this shift reveals where the ecosystem is actually head...
Rami Maalouf from Expo just eliminated the biggest barrier to iOS development: the Mac requirement. Windows and Linux developers can now build, test, and iterate on iOS apps with full Fast Refresh support.
Adrian Prantl from Apple's Debugger+Compiler Integration team reveals how Swift 6.4 is fixing a debugging problem most developers didn't know they had. The solution? Dramatically smaller binaries and faster, mo...
Keith Kurak from Expo makes a bold claim: AI coding agents don't eliminate the need for cross-platform frameworks. They actually make the case stronger.
Sneha Singla from Salesforce tackled what seemed impossible: building one real-time personalization system that works flawlessly across iOS, Android, React Native, and Flutter without breaking layouts or requir...
Kamil Delekta from Software Mansion reveals what nobody tells you about React Native's New Architecture: the migration flip is only 14% of the work. The other 86%? That's where things get interesting.
Alberto De Bortoli from Just Eat Takeaway built an over-the-air localization system that fixes translation bugs without app releases. No vendor SDK, no compromise—just a few hundred lines of code that works wit...
Antoine van der Lee, creator of RocketSim, is rethinking the iOS Simulator's role as AI agents take over coding. His latest move? Embedding the Simulator directly into Cursor, Claude Code, and Codex.
Joffrey Bion just dropped Kotlin Toolchain 0.12, and it's bringing the multiplatform publishing workflow developers have been waiting for. Plus, Wasm apps just got a whole lot more practical.
Antoine van der Lee tackles the most common SwiftUI mistake: slapping a view model on everything. His approach? Start simple, add MVVM only when it actually solves a problem.
