This slider example shows how to use gestures on iOS where keyboard events are not present in order to implement an ARIA slider. The example also uses a simplistic version of an announcer to announce the updates using ARIA live.
To use this on iOS with VoiceOver turned on, use the gesture override (double-tap and hold) and then drag the slider left or right.
Note: This slider does not implement all the functionality of a slider. It does not implement all of the ARIA authoring guidelines keyboard interaction.
