As you work in the design canvas, everything you edit is completely in sync with the code in the adjoining editor. Code is instantly visible as a preview as you type, and any change you make to that preview immediately appears in your code.

Xcode recompiles your changes instantly and inserts them into a running version of your app — visible, and editable at all times. 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 rearrange controls with your cursor. Many of these visual editors are also available within the code editor, so you can use inspectors to discover new modifiers for each control, even if you prefer hand-coding parts of your interface.

You can also drag controls from your library and drop them on the design canvas or directly on the code. Dynamic replacement. Swift is everywhere. Get started with Swift. Download the free book. Download Xcode from the Mac App Store.

Swift Package Manager is a single cross-platform tool for building, running, testing and packaging your Swift libraries and executables.

Swift packages are the best way to distribute libraries and source code to the Swift community. Configuration of packages is written in Swift itself, making it easy to configure targets, declare products and manage package dependencies. New to Swift 5, the swift run command now includes the ability to import libraries in a REPL without needing to build an executable.

Swift Package Manager itself is actually built with Swift and included in the Swift open source project as a package.

Fast and Powerful From its earliest conception, Swift was built to be fast.
