Edit this Doc iOS 'mobile:': Element swipe

To swipe inside of an element you need to add the id of this element into swipe methods.

// find element to swipe inside
MobileElement el = (MobileElement) driver.findElement(MobileBy.id("my_id"));

// execute scroll
mobileScrollElementIOS(el, Direction.RIGHT);
mobileScrollElementIOS(el, Direction.LEFT);

// execute swipe
// !remember! to execute swipe in same direction as scroll use reverse direction
mobileSwipeElementIOS(el, Direction.LEFT);
mobileSwipeElementIOS(el, Direction.RIGHT);

/**
 * Performs scroll inside element
 *
 * @param el  the element to scroll
 * @param dir the direction of scroll
 * @version java-client: 7.3.0

    // final value depends on your app and could be greater
    final int ANIMATION_TIME = 200; // ms
    final HashMap<String, String> scrollObject = new HashMap<String, String>();

            break;
