About RichTextKit
RichTextKit is a library that lets you view and edit rich text in Swift and SwiftUI, on all major Apple platforms. The RichTextEditor supports text styles (bold, italic, underline, etc.), fonts, font sizes, colors, text alignments, image attachments, and much more. It's powered by a RichTextView that bridges UITextView & NSTextView and adds additional, platform-agnostic APIs that make the two views behave more alike.
