RichTextKit is a Swift SDK that helps you use rich text in Swift and SwiftUI. It has a multi-platform SwiftUI RichTextEditor that can be added to any app:

This editor supports text styles (bold, italic, underline, etc.), fonts, font sizes, colors, text alignments, image attachments, and much more.

The RichTextEditor is powered by a multi-platform RichTextView that bridges UITextView and NSTextView and adds APIs to make them work more alike on all platforms.

If you just want to view rich text, you can use the RichTextViewer SwiftUI view.

RichTextKit can be installed with the Swift Package Manager:

RichTextKit has a SwiftUI RichTextEditor that takes a text binding and a RichTextContext:

struct MyView: View {

    @State
    private var text = NSAttributedString(string: "Type here...")
    
    @StateObject
    var context = RichTextContext()

    var body: some View {
        RichTextEditor(text: $text, context: context) {
            // You can customize the native text view here
        }
        .focusedValue(\.richTextContext, context)
    }
}

The editor uses a RichTextCoordinator to sync changes between the editor, context, and platform-specific view. You can use the context to change font, colors, alignment etc. and observe context changes to update the UI.

If you just want to display rich text, you can use the RichTextViewer instead:

struct MyView: View {

    private var text = NSAttributedString(...)

    var body: some View {
        RichTextViewer(text: text)
    }
}

RichTextKit comes with a bunch of UI components, keyboard shortcuts & menu commands that make it easy to build a rich text editor.

For more information, please see the getting started guide.

The online documentation has more information, articles, code examples, etc.

The demo app lets you explore the library on iOS and macOS. To try it out, just open and run the Demo project.
