Xcode 11 includes everything you need to create amazing apps and to bring your apps to even more devices. Take advantage of SwiftUI, an all-new user interface framework with a declarative Swift syntax. Start bringing your iPad app to Mac with just a click. And with support for Swift packages, Xcode 11 lets you share code among all of your apps or use packages created by the community.

SwiftUI is an innovative, exceptionally simple way to build user interfaces across all Apple platforms with the power of Swift. Build user interfaces for any Apple device using just one set of tools and APIs. With a declarative Swift syntax that’s easy to read and natural to write, SwiftUI works seamlessly with new Xcode design tools to keep your code and design perfectly in sync. SwiftUI is truly native, so your apps directly access the proven technologies of each platform to beautifully implement everything users love about the Apple ecosystem.

Declarative syntax. Write simpler code with a declarative Swift syntax that clearly states what your user interface should do.

Design tools. Drag and drop to construct or edit your interface. Quickly make changes to visual UI elements with pop-up inspectors.

Native on all Apple platforms. Your apps gain incredible native performance and take advantage of the proven technologies, controls, and user experiences of Apple platforms to feel fully integrated.

Live mode. See your design change instantly in one or many exact previews. Switch the design canvas to live mode to instantly interact with your running app in Xcode or on a connected device.

Xcode makes it easy to get a huge head start on turning your existing iPad app into a native Mac app. Your Mac and iPad apps share the same project and source code, so any changes you make translates to both platforms. And your newly created Mac app runs natively, utilizing the same frameworks, resources, and even runtime environment as apps built just for Mac.

Whether you prefer a single editor or split your windows into a precisely-arranged mosaic, Xcode 11 gives you total control over your coding area and the ability to split any editor pane. Editors can also show SwiftUI previews, live views of playgrounds, and a myriad of assistants. If you need to focus on just one file, you can click-zoom to maximize the pane, and return to exactly where you were before. The new minimap sidebar shows a birds-eye view of the open file, including highlights that make it easy to jump to the right place.
