Hi there,

I am trying to automate iOS app using simulator on my Mac with the help of Appium. Specified the app in App path and done everything that is needed. I could able to launch the server but unable to start the inspector by clicking icon the app. Simulator is getting launched but after loading, its getting killed and it is happening in loop.
