Yes, because the componentWillMount and componentWillReceiveProps getting deprecated soon in React. I suggest you to use componentDidMount instead of componentWillMount.
But you will still get those yellow box warnings because react-native is still using those for the internal components like Image, TouchableOpacity and a lot of other components. We need to wait for a new update to get rid of those warnings. Don't worry, Happy coding.
