Im on macOS 12, Xcode 13 b5 and nothing shows for me. I get a lot of web page proxy errors.

looks like there is some typo in SwiftUIViewRepresentable

    private func getWebView(context: Context) -> CodeWebView {
        let codeView = CodeWebView()

        codeView.setReadOnly(isReadOnly)
        codeView.setMode(mode)
        codeView.setFontSize(fontSize)

        codeView.setContent(content)
        codeView.clearSelection()

        codeView.textDidChanged = { text in
//            context.coordinator.set(content: text) //  <----
             if content != text && !text.isEmpty {      //  <---- but one more problem on select-remove or on remove last char; looks like lib returns empty string before any change... this needs to be handled
                 content = text                                      //  <----
            }                                                                 //  <----
            self.textDidChanged?(text)
        }

        colorScheme == .dark ? codeView.setTheme(darkTheme) : codeView.setTheme(lightTheme)

        return codeView
    }

    private func updateView(_ webview: CodeWebView, context: Context) {
        if context.coordinator.colorScheme != colorScheme {
            colorScheme == .dark ? webview.setTheme(darkTheme) : webview.setTheme(lightTheme)
            context.coordinator.set(colorScheme: colorScheme)
        }

      webview.setContent(content) // <----
      webview.clearSelection() // <----
    }

the problem is that "aceEditorDidChanged" returns at first value and than empty string - at any change (maybe indicator of end line or so...) but this triggers the issue
