I have a scroll view, that will generate a number of different views to create a timeline. I want this scrollview, of unknown length to be exported to multiple PDF pages. How would I do this? I have found a way of converting an entire view to a PDF (https://stackoverflow.com/questions/60753436/convert-swiftui-view-to-pdf-on-ios?noredirect=1&lq=1), and I couldn't really get that to work on a view let alone a ScrollView. Any ideas?

Here is my scroll view code - both HomeArm and AwayArm are separate views that build the timeline icon, I don't think they're relevant to creating the PDF though:

ScrollView(.vertical){
    VStack(spacing: 0){         
        ForEach(processor.matchEvents){event in
            if(event.team.home == true){
                HomeArm(team: event.team, event: event)
            }
            else{
                AwayArm(team: event.team, event: event)
            }
       }
    }
}
.frame(width: 475, height: 1100, alignment: .center)

You need to setup the data you want to send to pdf. Format the information in a similar way to how you formatted the views (if that's waht you want) then render the pdf. You may not get the 100% exact view you are after, but it's a pdf not a screenshot of the screen. So think about it differently.

        render.setValue(NSValue(cgRect: page), forKey: "paperRect")
        render.setValue(NSValue(cgRect: printable), forKey: "printableRect")

        // 4. Create PDF context and draw
        let rect = CGRect.zero

        let pdfData = NSMutableData()
        UIGraphicsBeginPDFContextToData(pdfData, rect, nil)

        for i in 1...render.numberOfPages {

            UIGraphicsBeginPDFPage();
            let bounds = UIGraphicsGetPDFContextBounds()
            render.drawPage(at: i - 1, in: bounds)
        }

        UIGraphicsEndPDFContext();

        // 5. Save PDF file

        do {
            try pdfData.write(to: outputFileURL, options: .atomic)

            print("wrote PDF file with multiple pages to: \(outputFileURL.path)")
        } catch {

             print("Could not create PDF file: \(error.localizedDescription)")
