for i OS better use native predicate instead of XPATH:

List<IOSElement> elementList = driver.findElements(MobileBy.
                iOSNsPredicateString("type == 'XCUIElementTypeStaticText' AND name == '" + name + "' AND visible == 1"));
        if (!elementList.isEmpty()) {
             // element found on screen
        }
