SwiftUI is an innovative, exceptionally simple way to build user interfaces(UI) across all Apple platforms, including iOS, iPadOS, MacOS, WatchOS and tvOS with the power of Swift.
SwiftUI is Apple's framework used to 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. Automatic support for Dynamic Type, Dark Mode, localization, and accessibility means your first line of SwiftUI code is already the most powerful UI code you have ever written.
Design Tool
SwiftUI provides views, controls, and layout structures for build your app's UI Design. You can preview a SwiftUI view side-by-side with its code - a change to one side will update the other side, so they’re always in sync with Code & Design. And it’s code, but a lot less than you had write for UIKit, so it’s easy to understand, edit and debug.
Drag and drop
Arrange components within your user interface by simply dragging controls on the canvas. Click to open an inspector to select font, color, alignment, and other design options, and easily re-arrange controls with your cursor.
Dynamic replacement
The Swift compiler and runtime are fully embedded throughout Xcode, so your app is constantly being built and run. The design canvas you see isn’t just an approximation of your user interface — it’s your live app.
Declarative Syntax
SwiftUI uses a declarative syntax so you can simply state what your user interface (UI) should do. For example, you can write that you want a list of items consisting of Button, then describe alignment, font, and color for each field. The code is simpler and easier to read , saving you time and maintenance.
This declarative style even applies to complex concepts like animation and other. We can Easily add animation to almost any control and choose a collection of ready-to-use effects with only a few lines of code.
Native on All Apple Platforms
SwiftUI was built on decades of experience in creating the most innovative and perfect user interfaces. SwiftUI is truly native, so your apps directly access any technologies of each platform with a small amount of code and an interactive design.
