AI agents typically interact with iOS apps via slow, expensive screenshot-based vision — analyzing pixels to infer tap coordinates. Accessibility trees (VoiceOver's structured element hierarchy) offer a faster, cheaper alternative: deterministic navigation by identifier, precise coordinates, minimal tokens. The author provides practical SwiftUI patterns for populating accessibility trees comprehensively and a coordinate-tracking toolkit for simulator-based agent automation.
