RocketSim for Xcode Simulator
RocketSim extends Xcode Simulator so you can test iOS and iPadOS apps, investigate problems, and prepare screenshots and demos without repeatedly switching tools.
by SwiftLee
What you get
You can test app behavior and prepare visuals alongside Xcode Simulator.
You get ways to reproduce tricky app behavior without repeatedly changing settings or reaching for a device. Simulate slow, unreliable, or disconnected networking for your running app without slowing your Mac, then inspect requests and responses. You can also trigger universal links and push notifications, simulate locations, and change permissions without reinstalling your app.
You can check whether your interface matches the design by overlaying Figma, Sketch, or Zeplin frames on the live app. Grids, rulers, and pixel zoom help you spot spacing and color differences, while accessibility overrides and a keyboard-navigable VoiceOver overlay help you test different viewing and navigation needs.
When you need to show your work, you can capture screenshots and recordings, add device bezels and touch callouts, trim clips, and export GIFs or App Store Connect-friendly previews. You also get local build-duration trends to compare builds across Xcode versions.
