Important
CodeEditSourceEditor is currently in development and it is not ready for production use.
Please check back later for updates on this project. Contributors are welcome as we build out the features mentioned above!
This package is fully documentedhere.
CodeEditSourceEditor provides two APIs for creating an editor: SwiftUI and AppKit. The SwiftUI API provides extremely customizable and flexible configuration options, including two-way bindings for state like cursor positions and scroll position.
For more complex features that require access to the underlying text view or text storage, we've developed theTextViewCoordinators API. Using this API, developers can inject custom behavior into the editor as events happen, without having to work with state or bindings.

An AppKit API is also available.
