    WebDriver driver;
DesiredCapabilities capabilities = new DesiredCapabilities();

public void init() throws MalformedURLException, InterruptedException {
	capabilities.setCapability("platformName", "iOS");
	capabilities.setCapability("deviceName", "iPhone 5");
	capabilities.setCapability(CapabilityType.BROWSER_NAME, "safari");
	capabilities.setCapability("platformVersion", "9.3");
	//capabilities.setCapability("udid", "31C12FD6-8C33-4C58-AD0A-7AFF9A3DF74B");
	driver=new IOSDriver(new URL(""), capabilities);

	//driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
