SDK 54 deep dive, new APIs, and… a squircle? 😅

Published 23 days ago • 1 min read

Hey Reader,

This week I had the pleasure of talking with Beto from Expo in a brand-new podcast episode!

🎙️ “Expo SDK 54, Expo Router v6 & Expo UI Beta for iOS”

We unpack what’s new in SDK 54, what’s exciting about Expo Router v6, and how Expo UI is starting to tap into iOS 26 design like Liquid Glass.

👉 Listen to the episode here​

Some fun links from around the ecosystem this week:

  • 🔐 Expo App Integrity (alpha) — verify your app and secure your API calls without extra backend complexity
  • 💾 New LocalStorage API — hinted by Evan Bacon, this one works across native and web with shared logic
  • 🟦 React Native Squircle — yes, it’s a word, and yes, it’s beautiful. A new UI package I didn’t know I needed
  • 🌫️ SwiftUI Blur filter — iOS finally gets full blur support in React Native via a new PR. Super native feel unlocked.

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

💫 Nebula Notes

  1. ​Introducing Expo App Integrity (Module)
    Expo released the alpha version of a new package that allows to make your API calls more secure by verifying your app.
  2. ​New Localstorage API (Tweet)
    Evan Bacon hinted at the new localstorage API from SDK 54 which is more powerful and work across all platforms - even web.
  3. ​React Native Squircle (Library)
    I didn't know this was a word or that I would need it in my app, but the package looks so good I just have to use it in my next app.
  4. ​Blur Filter with SwiftUI (PR)
    React Native on iOS finally gets support for iOS blur filter, allowing once again for even more native integration.
