Infomaniak Rich HTML Editor

The Infomaniak Rich HTML Editor is a powerful Swift package designed to provide a seamless WYSIWYG (What You See Is What You Get) text editing experience across iOS, macOS, and visionOS platforms. Leveraging the power of the contenteditable HTML attribute, this editor allows you to effortlessly edit HTML content.

Built with UIKit and AppKit thanks to WebKit, it also includes a SwiftUI port, making it easy to integrate into modern Swift apps.

✍️ About

Installation

You can install the package via Swift Package Manager. Add the following line to your Package.swift file:

.package(url: "https://github.com/Infomaniak/swift-rich-html-editor.git", from: "1.0.0")

Usage

UIKit and AppKit

You can create the editor view and then add it to the view hierarchy.

import InfomaniakRichHTMLEditor
import UIKit

let editor = RichHTMLEditorView()
view.addSubview(editor)

To respond to editor's events, you can conform to RichHTMLEditorViewDelegate.

SwiftUI

The SwiftUI view is called RichHTMLEditor and takes two arguments:

html: Binding<String> the HTML content of the editor
textAttributes: TextAttributes the objects that contains the current state selected text (or the text at the insertion point) and is responsible to update the style

import InfomaniakRichHTMLEditor
import SwiftUI

struct ContentView: View {
    @State private var html = ""
    @StateObject private var textAttributes = TextAttributes()

    var body: some View {
        RichHTMLEditor(html: $html, textAttributes: textAttributes)
    }
}

The object TextAttributes contains various attributes about the current style of the selected text. Theses properties are read-only and are automatically updated by the editor. To update the style, you should call the corresponding functions such as bold().

Many modifiers are available to customize the editor and respond to editor's events. Here is a non-exhaustive list of modifiers:

RichHTMLEditor(html: $html, textAttributes: textAttributes)
    .editorScrollable(true)
    .editorInputAccessoryView(myToolbarView)
    .editorCSS("h1 { foreground-color: red; }")
    .onEditorLoaded {
        // Perform action when editor is loaded
    }
    .onCaretPositionChange { newPosition in
        // Perform action when caret moves
    }
    .onJavaScriptFunctionFail { error, function in
        // Perform action when an editor JavaScript function has failed
    }
    .introspectEditor { richEditorView in
        // Perform action on the editor (UI|NS)View
    }

Customize the editor

You can customize the editor with CSS. To target the editor, you should use the #swift-rich-html-editor selector.

For example:

#swift-rich-html-editor {
    padding: 16px;
}
