Description
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

What's new
- Version: 16.0.0
- Last Updated:
- New:
- RocketSim now supports connected physical iOS devices: USB-connected iPhones appear in live preview windows with side-window controls, screenshots, disconnect-safe video recording with audio, comparing overlays, and device-specific window positioning.
- Added Physical Devices settings for USB support, network-detected devices, and ignored devices, including an in-window option to hide a device you do not want RocketSim to manage.
- Added a dedicated `CLI & Agent` settings page with installers for the bundled `rocketsim` command line tool and agent skill. The CLI installs as a symlink into a folder you pick on your PATH, so App Store updates keep it up to date automatically.
- Added `rocketsim doctor` to verify the CLI install, RocketSim app discovery, IPC reachability, simulator state, AX permission, and snapshot-store readiness before you hand control to an agent.
- Added `rocketsim screenshot` as a plain PNG fallback command for agents and automations that need visual context.
Improved:
- VoiceOver overlay is now faster and more complete, including elements like tab bars and nav bars. CLI performance improved by 25x.
- Physical device windows are more reliable and polished, with dark preview chrome, full-bleed device bezels, corner resizing, restored window positions, cleaner USB discovery, and improved reconnect behavior.
- The agent protocol now emits one consistent `rs/1` JSON envelope with typed errors across `elements`, `screen`, `interact`, `wait`, `do`, `snapshot`, and `doctor`, making it easier for external agent skills and automations to consume reliably.
- Agent interactions are now more robust: `interact` settles against fresh snapshots, stale `--screen` hashes fail fast, screen-change waits advance to fresh snapshots, coordinate swipes route through real HID gestures, and `interact scroll` can resolve the nearest scrollable ancestor from a visible child element.
- Agent snapshots now surface sparse web content, perception recovery hints, and ambiguity hints for duplicate labels so agents can recover with visual fallback when accessibility data is incomplete.
Fixed:
- Fixed RocketSim Connect payload handling running on the main thread, reducing profiling noise and avoiding unnecessary main-thread compression work in linked apps. (Thanks, K. Titov!)
- App Actions add/edit sheets now always render in dark mode, matching the rest of RocketSim's floating UI. (Thanks, L. Tuss!)
- App Actions configurations shared via Git no longer regenerate identifiers on every launch, eliminating noisy diffs across team members and making the JSON file safe to commit. Locations are now imported from the file as well. (Thanks, N. Yun!)
- Network Monitoring now reconnects reliably after rerunning a simulator app without needing to restart RocketSim. (Thanks, Tonni Hyldgaard!)
- Fixed recordings automatically exporting visible touch indicators even when touches were turned off, while still keeping captured touches available in the post editor for retrospective enabling. (Thanks, G. Gerber!)
- Fixed automatic breakpoint installation for RocketSim Connect. (Thanks, L. Hurtado!)
- Fixed the Voice Over overlay getting stuck without elements when the active Simulator window was temporarily unavailable. (Thanks, A. Mohamad!)
- Fixed device bezels for iPhone 14 Plus, iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16 and iPhone 16 Plus rounding the screen content with the wrong radius, which left a transparent halo at the corners.
