可以在SwiftUI应用程序中显示PDF缩略图吗？

import SwiftUI
import PDFKit

struct PDFThumbnailView: View {
    var body: some View {
        VStack {
            PDFView(document: PDFDocument(url: URL(fileURLWithPath: "path/to/pdf/file.pdf")))
                .viewMode(.fit)
                .thumbnailViewMode(.sidebar)
                .frame(width: 200, height: 200)
        }
    }
}

struct ContentView: View {
    var body: some View {
        VStack {
            Text("PDF Thumbnail Example")
                .font(.title)
                .padding()
            
            PDFThumbnailView()
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
