问题
Today I've installed Xcode 9 and build my app for iPhone x. but the upper and bottom area showing black like the scenarios we met couple of years ago for iPhone 5 when screen switched to 3.5 to 4.
How simply we can fix this problem?

You should use a safe area.
For apps with custom layouts, supporting iPhone X should also be relatively easy, especially if your app uses Auto Layout and adheres to safe area and margin layout guides.

This below point helped for me to resolve that solution.
Ensure your app uses a Launch Screen storyboard (not Launch images).
