RocketSim integrates directly into the iOS Simulator environment, providing a floating toolbar that gives you instant access to powerful development utilities without leaving your testing flow. The design comparison feature lets you overlay reference images at adjustable opacity levels, enabling pixel-perfect UI implementation by comparing your simulator output against design mockups in real-time.
The accessibility audit system runs continuous checks against WCAG guidelines, flagging contrast ratio violations, missing labels, and touch target sizing issues as you navigate through your app. Network monitoring captures all HTTP traffic with detailed request and response inspection, allowing you to debug API calls, examine headers, and validate payload structures without external proxy tools.
Deep linking functionality provides instant URL scheme testing through a dedicated interface where you can construct and fire custom URLs, test universal links, and validate routing logic. The touch indicator visualization overlays visual feedback on every tap, swipe, and gesture, making it easy to record demonstration videos or debug gesture recognizer conflicts during development sessions.
Overlay reference designs directly onto the simulator screen with adjustable opacity controls. Drag and position mockups precisely, toggle visibility with keyboard shortcuts, and validate pixel-perfect implementation by comparing your running app against design files in real-time without switching between applications.
Automated accessibility checks run continuously as you navigate, identifying contrast ratio failures, missing accessibility labels, insufficient touch target sizes, and VoiceOver compatibility issues. Each violation includes the specific WCAG guideline reference and actionable remediation steps for immediate fixes.
Capture and inspect all HTTP and HTTPS network requests made by your app during simulator sessions. View detailed request headers, examine response payloads with JSON formatting, measure response times, and export traffic logs for debugging API integration issues without configuring external proxy servers.
Construct and trigger custom URL schemes, universal links, and deep links through a dedicated interface. Test routing logic, validate parameter parsing, and verify navigation flows by firing links directly into the simulator without manually typing URLs or using external trigger tools.
Display visual indicators for every touch, swipe, pinch, and gesture performed in the simulator. Customize indicator appearance with color and size options, perfect for recording demonstration videos, debugging gesture conflicts, or creating user interaction documentation with clear visual feedback.
Access all RocketSim features through a non-intrusive floating toolbar that stays visible while you work. Customize toolbar position, configure keyboard shortcuts for instant feature activation, and toggle visibility to keep your workspace clean while maintaining quick access to all development utilities.
