Xcode for Mac includes everything you need to create amazing apps for all Apple platforms. Now Xcode and Instruments look great in the new Dark Mode on macOS Mojave. The source code editor lets you transform or refactor code more easily, see source control changes alongside the related line, and quickly get details on upstream code differences. You can build your own instrument with custom visualization and data analysis. Swift compiles software more quickly, helps you deliver faster apps, and generates even smaller binaries. Test suites complete many times faster, working with a team is simpler and more secure, and much more.
Code you write in Xcode looks stunning as the dark X code interface makes your work the star of the show. The entire interface is tuned for your dark Mac experience, from icons, to fonts, to the subtle contrast color of the Jump Bar.
It also gives you powerful tools for creating your own dark apps for macOS. Interface Builder lets you quickly switch your design and preview from light to dark. Asset catalogs define assets and named colors. And you can switch your app in and out of Dark Mode while debugging. This is all done using controls within the tool that only apply to your app. No need to change your system settings.
