The following code scrolls the list but then throws InvocationTargetException:
@iOSFindBy(uiAutomator = ".tableViews()[2]")
private IOSElement filesContainer;
...
getFilesContainer().findElementByIosUIAutomation(".scrollUp()");
Here's the stacktrace: https://gist.github.com/RetAdmFloyd/fbb0ba98dbacad92a596
Though this code works well without any exceptions:
driver.findElementByIosUIAutomation(".tableViews()[2].scrollUp()");
