And your existing SwiftUI code continues to work, while providing faster performance, better diagnostics, and access to new controls. Your SwiftUI views can now be shared with other developers, and appear as first-class controls in the Xcode library. And a new widget platform built on SwiftUI lets you build widgets that work great on iPad, iPhone, and Mac. A brand new life cycle management API for apps built with SwiftUI lets you write your entire app in SwiftUI and share even more code across all Apple platforms.

SwiftUI offers new features, improved performance, and the power to do even more, all while maintaining a stable API that makes it easy to bring your existing SwiftUI code forward into Xcode 12. Choose any app from any of your teams, then quickly navigate to inspect crash logs, energy reports, and performance metrics, such as battery consumption and launch time of your apps when used by customers. And completions are presented much faster, so you can keep coding at maximum speed.Īn all-new design groups all critical information about each of your apps together in one place. You can also choose a unique font size just for Xcode within Preferences, including the traditional dense information presentation, and up to large fonts and icon targets.Ī new completion UI presents only the information you need, taking up less screen space as you type. The navigator now tracks the system setting for “Sidebar icon size” used in Finder and Mail. The navigator tracks the open files within your tabs using strong selection. You can re-arrange the document tabs to create a working set of files for your current task, and configure how content is shown within each tab. The new tab model lets you open a new tab with a double-click, or track the selected file as you click around the navigator.

New document tabs make it easy to create a working set of files within your workspace. The navigator defaults to a larger font that’s easier to read, while giving you multiple size choices.

Xcode 12 looks great on macOS Big Sur, with a navigator sidebar that goes to the top of the window and clear new toolbar buttons.
