Or take advantage of the processing horsepower of Mac to dramatically speed up testing using simulated devices running in parallel. Run unit tests, as well as UI and performance tests, across multiple physical devices at a time. It includes a robust testing engine built right in. These log points appear alongside other analysis events such as CPU, memory, or network usage to give you valuable insights into your code’s behavior. With virtually no overhead you can mark important points throughout your code, then track those signposts as your app runs in Instruments.

Using Instruments, you can finally retire your print() statements, which are replaced with OSLog signposts and your own custom instruments. To make your workflows easier and more secure, Xcode for macoS can even generate a unique SSH key for you and upload it to the server. It's never been easier for your team to work together in the cloud or on self-hosted servers within your organization.

Apple Xcode supports working directly with several collaboration platforms, including: Source control is the place where your whole team works on code together. With great Markdown support, your accompanying documentation will look great, too. Smooth animations are used throughout, whether folding your code to enhance focus, or when X code highlights errors and offers Fix-its. Text scrolls incredibly smoothly, even when editing enormous source files. The app includes a lightning-fast source code editor. This is all done using controls within the tool that only apply to your app. And you can switch your app in and out of Dark Mode while debugging. Asset catalogs define assets and named colors. Interface Builder lets you quickly switch your design and preview from light to dark. It also gives you powerful tools for creating your own dark apps for macOS. The entire interface is tuned for your dark Mac experience, from icons, to fonts, to the subtle contrast color of the Jump Bar. Xcode looks stunning as the dark X code interface makes your work the star of the show.
