iOS simulator doesn't launch my app

Question

I've installed the create-react-native-app , however I am facing an issue with my iOS simulator. It launch well but doesn't open my app and stay in the home screen. My android emulator behave as expected and the app is directly displayed. I've installed and updated XCode. The default device is an iPhone X but if i set to iPhone 6, it still open an iPhone X simulator.

Any suggestions ?
