Environment Overrides
Make your app accessible by using environment overrides like inverted colors or changing the dynamic type size.
VoiceOver Navigator
Visualize VoiceOver element order right on the Simulator
Testing VoiceOver used to mean grabbing a physical device, enabling VoiceOver, and swiping through your app to hear the order of elements. It works, but it pulls you out of your development flow — you’re constantly switching between Simulator and device, and the gesture-based navigation can feel slow when you’re iterating.
VoiceOver Navigator keeps you in the Simulator. It overlays numbered labels on each accessibility element in the same order VoiceOver would use, so you can see at a glance whether your reading order makes sense. You can:
- Arrow up and down — move through elements in VoiceOver order
- Arrow left and right — switch between rotor categories (like swiping on device)
- Enter — activate the focused element (e.g. tap a button); the app navigates and the overlay updates
- Search — find elements by name or type
- Rotor — manually select which rotor category to use
- Overlay — turn the numbered overlay on or off
- Stay in flow — verify accessibility behavior without moving to a physical device
No device, no gestures, no context switch. You get a much quicker loop for checking VoiceOver behavior while you develop.
Toggles and Dynamic Text
Toggle accessibility features like Increase Contrast, Reduce Motion, color filters, and Tinted Liquid Glass — and change Dynamic Type sizes — right from the side window, without navigating through Settings.
- Simulate color blindness and grayscale with adjustable intensity
- Tint Liquid Glass and adjust its opacity
- Show or hide StandBy on iPhone Simulators
- Stay in sync when you change settings in the Simulator itself
Accessibility Audit
Find accessibility issues before your users do
Audit the current screen for missing labels, small tap targets, low contrast, and VoiceOver problems. You get a score, findings grouped by rule, highlights on the Simulator, and a prompt you can hand to your AI agent.
- Run the audit from the Audit tab in the Accessibility window
- Automate audits, fixes, and validation with
rocketsim accessibility-audit - Let your agent fix the findings and run the audit again to validate
