Developer Steven Troughton-Smith has unearthed and leaked a video from Apple’s web servers that appears to show Xcode 10 running on macOS 10.14.
Troughton-Smith said he found the 30-second clip buried within an API on the backend of the Mac App Store.
Xcode 10 features a new dark interface alongside a darker Trash icon in the Dock. In macOS 10.13, there is a partial dark mode, but only for the dock and top menu bar.
The video also notes an Apple News icon in the dock, suggesting that this could become a desktop application.
The video itself also likely confirms rumors that the Mac App Store will be redesigned on macOS 10.14 to more closely resemble the App Store on iOS 11, including the addition of preview videos like this one for apps.
The leak comes just two days before Apple’s annual Worldwide Developers Conference, where the company is expected to preview macOS 10.14 alongside iOS 12, watchOS 5, and tvOS 12. WWDC opens with a keynote on Monday at 10:00 a.m. Pacific Time at the McEnery Convention Center in San Jose, California.
Stay tuned for additional details as they become available.
