iOS simulator crashes

Hi, I am trying to create a session with iOS driver, but the simulator crashes while booting and the process goes on for the other 2 times before my test logs as failed in the console. Why is it so?? and help on this is much appreciated.

public void amazon() throws MalformedURLException
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(“platformName”, “iOS”);
capabilities.setCapability(“deviceName”, “iPhone 6”);
capabilities.setCapability(“platformVersion”, “10.2”);
capabilities.setCapability(“browserName”, “Safari”);
driver = new IOSDriver(new URL(“”), capabilities);

Finally, I am able to fix the issue by following the steps posted by @menypeled
