Hey Reader,

New Essentials video just dropped!

This time we cover something every React Native dev eventually needs:

🎥 Platform-Specific Components, Layouts & Styling with React Native (iOS, Android & Web)

In this video you’ll learn:

• How to use the Platform API and platform-specific file extensions
• How to render custom layouts based on OS
• And how to tap into SwiftUI or Jetpack Compose using the Expo UI package

👉 Watch the video here

Also some 🔥 picks from the community this week:

• 🧠 Expo MCP Server Preview — a smarter layer for dev tooling + AI workflows, with big future potential
• 💾 MMKV v4 — a faster, Nitro Module-powered version of my favorite local storage lib (and only minimal breaking changes!)🚀
• New Architecture Performance Deep Dive — a great breakdown of why it’s finally time to migrate🧑‍💻
• Swift + Claude Code in Expo — Evan shared a quick flow for letting Claude build native features using Expo Modules

Links below — and as always, keep building & keep shipping.
