Not able to identify the elements in Web View in IOS simulator

I am not able to locate any of the elements in the webview.

Appium version is:1.5.3
IOS 9.3
Xcode 7.3

below is code snippet:
DesiredCapabilities cap = new DesiredCapabilities();
cap.setCapability(“platformName”, “iOS”);
cap.setCapability(“deviceName”, “iPad Retina”);
cap.setCapability(“appium-version”, “1.5.3”);
driver = new IOSDriver(new URL(“”),cap);

Set contextNames = ((IOSDriver) driver).getContextHandles();
int size1 = contextNames.size();
((AppiumDriver) driver).context((String)contextNames.toArray()[size1-1]);

when i try to locate element using xpath:

i am getting no such element exception.
