I'm building an iOS app in SwiftUI and need to adapt my UI when Voice Control is active — specifically to show labels on custom gesture-driven controls so they're accessible via Voice Control commands.
I've checked UIAccessibility and can find notifications and properties for VoiceOver (isVoiceOverRunning), Switch Control (isSwitchControlRunning), and AssistiveTouch (isAssistiveTouchRunning), but I can't find any equivalent for Voice Control.
UIAccessibility.isVoiceControlRunning and voiceControlStatusDidChangeNotification appear to exist on macOS (AXIsProcessTrustedWithOptions) but not on iOS.
Questions:
-
Is there a public iOS API to detect whether Voice Control is currently active — either a UIAccessibility property, notification, or SwiftUI environment value? If not, is the recommended approach to use UIAccessibility.isGuidedAccessEnabled as a proxy, or something else entirely?
-
Is there a private entitlement or capability that unlocks this detection for App Store apps?
What I've already tried:
Checking AccessibilityFeatures environment values in SwiftUI (@Environment(.accessibilityReduceMotion) etc.)
Thanks!
