Apple leaks macOS 10.14 dark mode, Xcode 10

Developer Steve Troughton Smith today tweeted photos of macOS 10.14 with some very juicy details about Apple's upcoming operating system. The OS is very clearly sporting a fresh new dark theme, presumably a toggle-able setting, with the dark UI affecting all application chrome. You can also see an icon for a Mac News app in the Dock, as well as a first look at Xcode 10.Smith explains that the API the Mac App Store uses behind-the-scenes is including a video preview for Xcode, something that the current Mac App Store does not support. It represents a pretty big leak on Apple's part ahead of Monday's keynote.

Another major leak because Apple just uploaded a video to a place where everyone can find it. Good work, Apple.

As far as dark modes go - I'm generally not a fan, because they often feel like tacked-on afterthoughts, without designers really taking the implications into consideration. The only time where I saw "dark mode" work well was Windows Phone, because that UI was designed for it from the ground-up. Also, dark modes tend to be "dark", and not black. With today's modern displays with deep blacks, dark mode should really be black mode.
