Run native app test in iOS 6.1 simulator

I set below capabilities to run my test
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(“appium-version”, “1.0”);
capabilities.setCapability(“platformName”, “iOS”);
capabilities.setCapability(“platformVersion”, “6.1”);
capabilities.setCapability(“deviceName”, “iPhone”);

It works well on iOS platformVersion 7.1.
Just changed platformVersion in code and simulator.
Its not working, throws below pop up

The application that opened iOS simulator failed to send all information(sessionUUID, sdkRoot, deviceInfo)

but i m testing native app in local path only

Maybe the application is not compiled for iOS 6.1? Posting the actual failure logs would be more helpful here.
