Software Developer @ Software Mansion; Building apps in React Native, finding simplicity in complexity.

[Krzysztof Magiera @kzzzf]

The iOS Simulator has never had a camera.

SimCam fixes that! Your simulator can use front, back or both cameras, each with its own source you control from the menu bar.

60 clap buttons across 17 articles, injected automatically via a Remark plugin. 👀

We used navigator.sendBeacon() instead of debounce. One request per session, fires on tab close.

spent some tokens vibe-coding a 3D embedding space visualization in React Native

the embeddings are computed locally using react-native-executorch, the visualization uses typegpu, co-authored by opus 4.7 max.

Runtime validation is killing your AI shader workflow. 😵
TypeGPU addresses that - type-safe primitives, less runtime surprises, GPU-driven simulation and rendering in pure TypeScript.

The power of WebGPU and the flexibility of TypeScript at your vibecoding fingertips, just use our newly added TypeGPU skill: ➡️

New Animation Backend

React Native 0.85 introduces a preview of the Shared Animation Backend, built in collaboration with Software Mansion.

This is a new internal engine that will power both Animated and Reanimated. It expands first class native animation support in core, and unlocks even faster native performance for Reanimated.

This is an experimental feature and will be available in 0.85.1 (shortly).

Many devs hear "on-device AI" and picture a massive model that just slows and overheats their phone. 🔋

But for tasks like Text-to-Speech or Computer Vision – it's a totally different story.

@_jakubchmura from our RN ExecuTorch team breaks down the pros and cons! ⬇️

[Software Mansion @swmansion]

There’s a lot you can learn from building 3 open-source React Native libraries in one week. 🚀

Check out @blazejkustra_’s thread for all the details 👇

[Gregory Moskaliuk @G_Moskaliuk]

Refining the details 💎

We’ve replaced the custom formatting bar in EnrichedMarkdownInput with native context menu integration.

It’s all about making things smoother and making the app feel truly native. 🚀

Gesture Handler 2.31 says hello 🫰

👉 Background pointers don’t block handlers anymore
👉 Handlers stay responsive after toggling display: none;
👉 pointerEvents is now handled correctly on buttons

Gotta admit, its fun watching an AI agent tap and swipe in an iOS app - even more when it gets a PR merged

Had an idea developing @swmansion's Argent: cloned @bluesky, picked the first open issue, let it run in the background. Came back to a fix... and the PR merged next day!

My dear front-end developers (and anyone who’s interested in the future of interfaces):

I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept):
Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow

@sebastienlorber @swmansion Thanks for the reminder @sebastienlorber, I just added it here😄

react-native-reshuffled 0.2.0 is here 🚀

Introducing onDragEnd callbacks based on @swmansion react-native-worklets

But that's not all:
Collisions, custom algorithms and more 👀

Check out new demo and visit
https://t.co/0ADfMrqmZo, for more details, we are so close to 100⭐️

[Wiktor Gut @wiktorgut_]

We've just hit the 100⭐️ milestone for react-native-reshuffled! 🔀

Thank you for the support and helpful comments. Can’t wait to see how you use it in your upcoming projects! 🛠️

The Migration Alert 🚨

react-native-markdown-display is officially unmaintained. Time to migrate to the successor built for the modern ecosystem.

⚡ Fully Native: Zero WebViews.
🏎️ md4c Parser: Fast & GFM compliant.
🧮 LaTeX: Built-in math rendering.
🔄 RTL & A11y: Native support.
✨ Native UX: Selection, image interactions, and more.

Don't let your app get stuck in the past. 🛠️
