Used Paul's sample code to share a PDF render of my ResultsView page, but XCode complains bitterly and PDF is empty. first part of log is:

In case it is not obvious, this is my debut App. Just completed 100 Days, so please excuse any horrendous coding faux pas ;-)

Code:

import SwiftUI

struct RegattaResults: View {
    @EnvironmentObject var regattaList : RegattaList
    @Environment(\.dismiss) var dismiss

    var body: some View {
        if regattaList.selectedRegatta.name == "Default Regatta" {
                Text("Please return to the Regatta tab to select a regatta")
        } else {
            Spacer()
            VStack {
                HStack {
                    Text("  < Regattas").onTapGesture {

                    }.foregroundColor(.blue)
                    Spacer()
                    Text(regattaList.selectedRegatta.name).font(.title2)

                // what else?
            }
            //print("processing - throwouts = \(regattaList.selectedRegatta.throwouts[regattaList.selectedRegatta.races.count])")

            skipper.regattaGross = 0
            skipper.regattaNet = 0
            for skipRaceScore in skipRaceScores {
                skipper.regattaGross = skipper.regattaGross + skipRaceScore.raceRawScore

    }
    func render() -> URL {
        // 1: Render Results with some modifiers
        let renderer = ImageRenderer(content:
                ResultsView(regatta: regattaList.selectedRegatta)
        )

        // 2: Save it to our documents directory
        let url = URL.documentsDirectory.appending(path: "regattaScores.pdf")

        // 3: Start the rendering process
        renderer.render { size, context in
            // 4: Tell SwiftUI our PDF should be the same size as the views we're rendering
            var box = CGRect(x: 0, y: 0, width: size.width, height: size.height)

            // 5: Create the CGContext for our PDF pages
            guard let pdf = CGContext(url as CFURL, mediaBox: &box, nil) else {
                return
            }

            // 6: Start a new PDF page
            pdf.beginPDFPage(nil)

            // 7: Render the SwiftUI view data onto the page
            context(pdf)

            // 8: End the page and close the file
            pdf.endPDFPage()
            pdf.closePDF()
        }

        return url
    }

}

Looks as if the runtime error logs in the console are also genertaed by Paul's example code, and don't stop the share from working. Now my issue is the blank pdf generated. It seems to be sized for the view OK, but no visible content. Any ideas?
