Just before the start of WWDC 2018, a video from the server Apple with new macOS 10.14 features was leaked to the network. It demonstrates macOS 10.14 with Xcode 10, the Apple News program, and a video preview on Mac App Store.
Xcode 10 also shows dark mode, the icons in the dock are also darker. This indicates that macOS 10.14 and iOS 12 will finally add an official dark mode. MacOS already has a variation of it, but it cannot be called complete.
Ladies and gentlemen, I give you Xcode 10 on macOS 10.14. Dark Appearance, Apple News, App Store w / video previews pic.twitter.com/rJlDy81W4W

In the video you can also see the icon Apple News in the dock, which means it will appear in the new version.
In addition, Mac updates are shown App Store, namely a video preview and a new interface similar to App Store in iOS 11. New wallpapers similar to the landscape of the Mojave Desert, which is a reference to the name macOS 10.14.
Apple will present macOS 10.14 with iOS 12, watchOS 5 and tvOS 12 tomorrow, June 4th.
