Turning SwiftUI Views into PDFs: A Quick How-To

Need to generate a PDF from a SwiftUI view? Whether it's for sharing a report, creating a simple document, or any other purpose, SwiftUI's ImageRenderer offers a straightforward way to achieve this. Here's a handy function that takes a SwiftUI view (ViewForPDFOutput in this example) and returns the URL of the generated PDF file: struct Example: View { var body: some View { VStack { Text("demo") } .toolbar { buildShareButton() } } private func buildShareButton() -> some ToolbarContent { ToolbarItem(placement: .topBarTrailing) { ShareLink(item: getPdfUrl()) { Image(systemName: "square.and.arrow.up") } } } private func getPdfUrl() -> URL { let renderer = ImageRenderer( content: ViewForPDFOutput().frame(width: 500) ) let url = URL.documentsDirectory.appending(path: "swiftui_output.pdf") renderer.render { size, context in var box = CGRect(x: 0, y: 0, width: size.width, height: size.height) guard let pdf = CGContext(url as CFURL, mediaBox: &box, nil) else { return } pdf.beginPDFPage(nil) context(pdf) pdf.endPDFPage() pdf.closePDF() } return url } } Note: It's important to give width to view which you want to make pdf. .frame(width: 500)

struct Example: View {
    var body: some View {
        VStack {
            Text("demo")
        }
        .toolbar {
            buildShareButton()
        }
    }

    private func buildShareButton() -> some ToolbarContent {
        ToolbarItem(placement: .topBarTrailing) {
            ShareLink(item: getPdfUrl()) {
                Image(systemName: "square.and.arrow.up")
            }
        }
    }

    private func getPdfUrl() -> URL {
        let renderer = ImageRenderer(
            content: ViewForPDFOutput().frame(width: 500)
        )
        let url = URL.documentsDirectory.appending(path: "swiftui_output.pdf")

        renderer.render { size, context in
            var box = CGRect(x: 0, y: 0, width: size.width, height: size.height)

            guard
                let pdf = CGContext(url as CFURL, mediaBox: &box, nil)
            else {
                return
            }

            pdf.beginPDFPage(nil)
            context(pdf)
            pdf.endPDFPage()
            pdf.closePDF()
        }

        return url
    }
}

.frame(width: 500)
