Hi ... to swipe a element this code worked for me... try if it works....
WebElement element1=driver.findElement(By.xpath("//UIAApplication[1]/UIAWindow[1]/UIATableView[2]/UIATableCell[2]"));
TouchAction act=new TouchAction((MobileDriver) driver);
act.longPress(192,284).waitAction(2000).moveTo(element1, 80, 100).perform().release();
