This enhancement is particularly beneficial, as it introduces an event that empowers users to effortlessly retrieve an array of applied formats. By capturing content changes through our delegate method and manually invoking the click event, users gain streamlined access to a comprehensive array of string-based formats that have been applied

Example Code:

extension TestViewController: RichEditorDelegate {

    func richEditor(_ editor: RichEditorView, handle action: String) {

        let commaSeparatedString = action
        let arrayOfStrings = commaSeparatedString.split(separator: ",").map { String($0) }

        buttonStateChange(
            isSelected: arrayOfStrings.contains("unorderedList") ? true : false,
            format: .bulletPoint
        )

    }

   func richEditor(_ editor: RichEditorView, contentDidChange content: String) {

       editor.runJS("document.querySelector('body').click();")

        if content.count > 40000 {
            editor.html = prevText
        } else {
            prevText = content
        }

    }

}
