I would say that you need to use PDFKit view object inside a SwiftUI component like I did to use a TextView in ly SwiftUI appThis is a simplified version : import SwiftUI
import os
let uiLog = OSLog(subsystem: "com.visual-science.CryptiK", category: "UI")
class EditorCoordinator : NSObject, NSTextViewDelegate {
let textView: NSTextView;
let scrollView : NSScrollView
let text : Binding<NSAttributedString>
init(binding: Binding<NSAttributedString>) {
text = binding
textView = NSTextView(frame: .zero)
textView.autoresizingMask = [.height, .width]
textView.textStorage?.setAttributedString(text.wrappedValue)
textView.textColor = NSColor.textColor
scrollView = NSScrollView(frame: .zero)
scrollView.hasVerticalScroller = true
scrollView.autohidesScrollers = false
scrollView.autoresizingMask = [.height, .width]
scrollView.documentView = textView
super.init()
textView.delegate = self
}
func textDidChange(_ notification: Notification) {
switch notification.name {
case NSText.didChangeNotification :
text.wrappedValue = (notification.object as? NSTextView)?.textStorage ?? NSAttributedString(string: "")
default:
os_log(.error, log: uiLog, "Coordinator received unwanted notification")
}
}
}
struct DataTextEditorView: View, NSViewRepresentable {
typealias Coordinator = EditorCoordinator
typealias NSViewType = NSScrollView
let text : Binding<NSAttributedString>
func makeNSView(context: NSViewRepresentableContext<DataTextEditorView>) -> DataTextEditorView.NSViewType {
os_log(.info, log: uiLog, "%@", context.coordinator.scrollView)
return context.coordinator.scrollView
}
func updateNSView(_ nsView: NSScrollView, context: NSViewRepresentableContext<DataTextEditorView>) {
os_log(.debug, log: uiLog, "%@", context.coordinator.self)
os_log(.debug, log: uiLog, "%@", text.wrappedValue)
}
func makeCoordinator() -> EditorCoordinator {
os_log(.info, log: uiLog, "makeCoordinator")
let coordinator = EditorCoordinator(binding: text)
return coordinator
}
}This is the kind of thing you need to do to use UIKit/AppKit UI element in a SwiftUI based AppRegardsGerard

Well my own answer, can be useful for others.I hesitated to use my own button style ... but this is the solution here in my casestruct SimpleButtonStyle: ButtonStyle {
func pressColor(isPressed: Bool) -> Color{
if isPressed {
return Color.gray
}
else {
return Color.white
}
}
func makeBody(configuration: Self.Configuration) -> some View {
configuration.label
.padding([.trailing, .leading], 10)
.padding([.top, .bottom], 1)
.background(
RoundedRectangle(cornerRadius: 5)
.fill(pressColor(isPressed: configuration.isPressed))
.overlay(RoundedRectangle(cornerRadius: 5)
.stroke(lineWidth: 1)
.foregroundColor(Color.gray)
)
)
}
}
struct SomeButton : View {
var body: some View {
HStack{
Button(action: {
print("Pressed")
}) {
Text("Press")
}
}
.buttonStyle(SimpleButtonStyle())
.font(.headline)
.padding(.trailing, 10)
}
}Take care
