The only keyword which can interact with my IOS elements is 'Double Tap'

For anyone interested, this is how I navigated around the problem

class Tapper {
	int x;
	int y;

	/**
	 * Find test object and tap it based on attribute values x and y.	
	 * @param String Katalon test object
	 */
	@Keyword
	def tapObject(String to) {
		KeywordUtil.logInfo("Attempting to finding x and y coordinates of test object: " + to);
		x = Integer.parseInt(Mobile.getAttribute(findTestObject(to), 'x', 30));
		y = Integer.parseInt(Mobile.getAttribute(findTestObject(to), 'y', 30));
		KeywordUtil.logInfo('Found test object coordinates: '+x+', '+y);
		Mobile.tapAtPosition(x * 2, y * 2);
	}
}
