Convert view to PDF

Please reformat your code. The top part isn't inside the code block, so it's difficult to read.

Where in code does it crash ?

What is the error message if any (crashlog) ?

Button code reformatted:

Button(action: {
    if included && !saving {
        if signatureImage != nil {
            exportPDF(name: "ToR-\(patient.name)-\(patient.id)") {
                self
            } completion: { status, url in
                if let url = url, status {
                    self.PDFUrl = url
                    self.showActionSheet.toggle()
                    print("URL => \(url) - Status \(status)")
                } else {
                    print("Failed")
                }
            }
        } else {
            self.scrollToBottom = true
        }
    }
}) {
    if saving {
        ProgressView()
            .tint(Color("MainColor"))
            .scaleEffect(1.5)
    } else {
        Text(NSLocalizedString("Save", comment: ""))
    }
}
