Step 1: Confirm runtime context

Identify simulator UDID target first (axe list-simulators).
Simulator-interaction AXe commands require --udid <UDID>. Commands like list-simulators and init do not.
Run axe describe-ui --udid <UDID> to inspect the full current screen. Use axe describe-ui --point <X,Y> --udid <UDID> to inspect the element at a specific coordinate. Use the output to discover available --id and --label values for selector taps and slider setting, and to confirm coordinates for coordinate-based taps.
Prefer selectors (tap --id / tap --label, slider --id / slider --label) over raw coordinates. Selectors are resilient to layout changes, work across device sizes, and support element waiting where documented. For UIKit UISwitch and SwiftUI Toggle rows, selector taps activate the contained switch/toggle when the match contains exactly one such control. Default tap style is automatic: switches/toggles use physical touch down/up, while normal taps use simulator tapAt.

Step 2: Choose the right command

Available commands: init, tap, slider, swipe, drag, gesture, touch, type, button, key, key-sequence, key-combo, batch, describe-ui, screenshot, record-video, stream-video, list-simulators. Run axe --help or axe <command> --help for full options.
