How to make selected option highlighted?

[sonnguyen9800]

Hello,

I am trying to integrate this project using SwiftUI. The general concept of the app is to make a todo-list app that allow rich text editing.

For now, I am trying to customize the app by make the selected options ("bold", "italic", "underline") to be highlighted (to be brighter, color changed, etc) when that options be chosen? How can I do that?

Current implementation of the app is similar to this:

struct Cbess : UIViewRepresentable {
    
    @Binding var textHtml: String
    
    func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }
    
    func makeUIView(context: Context) -> RichEditorView {
        
        let editorView = RichEditorView()
        editorView.delegate = context.coordinator
        return editorView
    }
    
    func updateUIView(_ uiView: RichEditorView, context: Context) {
    }
    
    class Coordinator: NSObject, RichEditorDelegate {
        
        var parent: Cbess
        
        init(_ parent: Cbess) {
            self.parent = parent
        }
        
        // Use delegate here
        func richEditor(_ editor: RichEditorView, contentDidChange content: String) {
            self.parent.textHtml = content
            print(content)
        }
    }
}

The above UIViewRepresentable is wrapped inside on SwiftUI View.
