Crashes are the worst kind of errors your users can face—they stop your app with no warning. Some show up during development and get fixed quickly, but others only appear in production. You can catch the latter without third-party tools via Xcode’s Organizer or App Store Connect

You can’t fix performance issues if you don’t know they exist. While Apple’s metrics catch most problems, sometimes you need users to report UX and performance bugs directly. In @helm_app, we use our own tool enriched with @twannl’s privacy-friendly Diagnostics library 📊

Want to audit your app for memory leaks without guesswork or stopping execution to inspect the memory debugger? 💪 Just spin up the Leaks instrument, use your app as you normally would, and get a clear visual indication of any instances that leak along the way.

👀 If you use Foundation Models in, this one line change could have a big impact on your first request to a Language Model Session! By default, model resources load lazily on the first request. Call prewarm and load them at app launch instead to speed up your first request!

During WWDC this year, Apple introduced a brand-new Instrument to help optimize your app’s impact on battery life: Power Profiler. 💡 Even better, Apple also added a Control Center action that lets you measure your app’s performance directly on-device without Xcode and capture

My goal for 2026 is to launch my very first game. It’s been decades in the making, and if you’re a fan of collectible card games, stay tuned!

There’s one setting in the Developer menu you should enable today 👀 Hang Detection gives you visual feedback when hangs occur for TestFlight & Development builds on your device and automatically collects diagnostics, giving you the best chance at fixing them!

It mostly flew under the radar, but at this year’s WWDC Apple added a new App Store Connect API endpoint to fetch power & performance metrics for the latest version of your app. You can programmatically access data like hangs, memory usage, and more 👀 This unlocks some really

Sometimes the most impactful changes are not hard to implement! 🚀 3 lines of code == 100x faster!

Not all performance improvements require a lot of research and code changes! Don't underestimate the power of low-effort wins like this one! 💡 This is a 3 lines of code trick I use all the time in @helm_app that makes parsing responses ~100x faster!
