RocketSim enhances the Xcode Simulator for iOS and iPadOS development: boost productivity and streamline your workflow with capture, networking, build insights, and quick actions beside the Simulator. Developers report building, testing, and verifying apps up to 2x faster per RocketSim Developer Research. Key Highlights - Polish screenshots and App Store Connect preview videos: open captures in the editor from the floating thumbnail, then tune bezels, touches, backgrounds, metadata, trim, and GIF export with App Store Connect-friendly dimensions—ideal for Swift, SwiftUI, and UIKit demos - Debug networking without proxy certificates: throttle or drop traffic, Airplane Mode for your running app only, and inspect traffic via RocketSim Connect; use Copy Summary when you need a redacted line to paste into Slack or an agent prompt - Track local build time trends next to Xcode with Build Insights across versions - Exercise universal links, APNs payloads, GPS and time zones, environment overrides, and a VoiceOver overlay with keyboard navigation from the side window - Pro: Simulator framebuffer recording up to 120 fps for fluid motion Feature Breakdown Screenshots and Recordings - Start from the Captures tab in the side window; after capture, refine in the editor before export - Bezels, touch callouts, optional metadata, audio, trim, GIF conversion - Pro: 120 fps framebuffer recording when supported Networking - Simulate slow or lossy networks without slowing your Mac - Per-app Airplane Mode in the Simulator only - Inspect requests and responses; metrics; cURL export; trace export; Copy Summary for redacted sharing - Speed control and monitor share a dedicated Networking area in the side window for quicker discovery Accessibility - VoiceOver overlay with keyboard navigation for testing in the Simulator without juggling a device as often - Environment overrides from the side window: Bold Text, Dark Mode, Dynamic Type, and more—without opening Settings.app - Tinted Liquid Glass legibility live on iOS 26 simulators Build Insights - Build count and duration trends in the main and side windows - Compare performance across Xcode versions your team runs Quick Actions for Builds - Clear Derived Data globally or for the current app - Open common app folders without Finder archaeology - Grant, revoke, or reset permissions without reinstall churn Compare Designs - Overlay Figma, Sketch, or Zeplin frames on live UI - Slider mode for pixel-level SwiftUI and UIKit checks Design Tools and Magnify - Grids and rulers in on-screen points; slow animations for layout polish - Pixel zoom with color sampling as code Deeplinks and Push Notifications - Fire universal links and push payloads with the debugger attached - Actions from recent builds; clipboard URL history; shareable Quick Action groups - Grid or list layout for long route or push lists Location Simulation - Routes or single-pin GPS; time zones from a chosen place; Maps and travel flows User Defaults Editor - Live-edit standard and App Group defaults—flags, debug toggles, plist-backed state Simulator Camera - Mac camera in Simulator for AVFoundation, QR, and Vision-style demos Full Customization - Menu bar access including Open GitHub Issues - Shortcuts and floating windows matched to your workflow Trusted by Developers Everywhere RocketSim is used daily by thousands of developers and 200+ teams—including teams at Meta, Runkeeper, and MacWhisper—to ship iOS apps with less friction. It fits TestFlight, App Store Connect, the Apple Developer app, and everyday Xcode use. Xcode® is a trademark of Apple Inc., registered in the U.S. and other countries.

Last update:
New: - Added iPad A16 device bezels (Thanks, H. v.d. Ploeg!) - Physical-device previews now support Simulator’s Command-1/2/3/4 viewing modes: Physical Size, Point Accurate, Pixel Accurate, and Fit Screen. - The side window now appears for Simulators in Xcode’s Device Hub, including expanded mode. Fixed: - Prevented crashes in floating capture thumbnails during recording export. - Prevented side-window crashes caused by invalid or stale frames during spring animations. - Improved Magnifier stability and performance during rapid movement and zooming. - Stopped the optional RocketSim Connect setup prompt from reappearing after dismissal. - Corrected the Simulator side window when switching Spaces. - Restored launch arguments, including locale overrides, for physical-device apps. - Corrected captures, recordings, and touch indicators after Simulator rotation. - Prevented deep links and push notifications from switching Device Hub to Simulator.app. - Prevented occasional deadlocks when relaunching apps with a locale or time zone. - Prevented RocketSim Connect from leaving app launches paused at `UIApplicationMain` after the debugger briefly auto-resumed during setup. - Prevented a crash when RocketSim became active after closing the sales window. - Made `rocketsim interact tap x y` send precise HID touches instead of activating an enclosing accessibility element. Use `interact activate` for accessibility activation. (Thanks, S. Gardner!) - Corrected landscape coordinates for agent taps, swipes, and gestures so they land where `elements` reports them. (Thanks, S. Gardner!) - Corrected `rocketsim screenshot` and `snapshot` orientation on rotated Simulators. PNGs now match the orientation and coordinate space reported by `elements`. (Thanks, S. Gardner!) - Included accessibility elements as small as 1×1 points in `rocketsim elements`. Zero-size elements with accessibility content are now reported under `zero_size_elements_omitted`. (Thanks, S. Gardner!) - Kept sibling accessibility elements with identical text separate in `rocketsim elements`. (Thanks, S. Gardner!) - Reported malformed Simulator accessibility responses as unavailable instead of crashing RocketSim. - Prevented disconnected CLI sockets from terminating RocketSim while writing a response. - Diagnostics now show the latest RocketSim Connect LLDB injection result and any recovery paths used. - Agent `elements` output now includes each element’s `accessibilityIdentifier` in debug mode and uses it for identity, preventing same-labeled elements from colliding in `interact` deltas. (Thanks, S. Gardner!) - Restored Build Insights after license validation refreshes stale cached metadata. - Replaced a misleading user-directory warning with the actual Xcode selection problem. (Thanks, H. v.d. Ploeg!) - Restored the Subscribe button when StoreKit confirmation was not anchored to the originating RocketSim window.
