Need help with swiftUI

[DuoTunlH]

I am trying to use the library in SwiftUI and followed the example exactly. However, I am facing an issue where, when I update the attributedText from a button action like this:

ProtonView(attributedText: $att, selectedRange: $selectedRange)
Button("Button") {
    att = att.addingAttributes([.foregroundColor: UIColor.red], to: selectedRange)
}

The attributedText in the EditorView doesn't update as expected. The changes made to the att (such as adding attributes to the text) don't reflect in the EditorView.

In ProtonWrapperView, if I use the following code to update the EditorView:

    func updateUIView(_ view: EditorView, context: Context) {
        view.attributedText = attributedText
    }

The attributedText updates as expected, but I receive the warning:
Modifying state during view update, this will cause undefined behavior.

Can anyone help me figure out how to correctly update attributedText in the EditorView so that changes are reflected?
