i have been trying to run test appium script on emulator but have been encountering Instrument start up crash issue.

here is the capabilities setup
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(“deviceName”, “iPhone 6s”);
capabilities.setCapability(“platformName”, “iOS”);
capabilities.setCapability(“platformVersion”, “9.2”);
capabilities.setCapability(CapabilityType.BROWSER_NAME, “safari”);
wd = new IOSDriver(new URL(“http://127.0.0.1:4723/wd/hub”), capabilities);//instantiate driver
