Expo Brings iOS Simulators to the Browser

Running an iOS simulator usually means sitting at a Mac with Xcode installed. Expo is moving the iOS simulator into the browser instead.

That means no Xcode, no setup, and no waiting—you can run your app on a real iOS simulator from anywhere.

What Happened

Expo is bringing iOS simulators to the browser. The feature gives React Native developers a real iOS simulator without needing the usual local environment.

Why It Matters

It removes the setup friction that keeps you tied to one machine. If it holds up, testing an iOS build becomes something you can do from any browser—and that really does change how apps get developed.
