How to create a PDF/A file in Swift?

Question

I'd like to create a PDF/A file in my iOS app but don't really know where to start.

My actual code (which generates a simple PDF) is:

_ = UIGraphicsBeginPDFContextToFile(temporaryPdfFilePath, paperSize, nil)
UIGraphicsBeginPDFPageWithInfo(paperSize, nil)
let currentContext: CGContextRef = UIGraphicsGetCurrentContext()!

...drawing...

UIGraphicsEndPDFContext()

Is there any API or something else to follow?

Hey, did you find a solution? :) – SamuelTJackson Dec 16 '16 at 09:38 — SamuelTJackson, Dec 16 '16 at 09:38
Nope, I tried a lot about it but nothing to do :( – Fabrizio Dec 16 '16 at 13:02 — Fabrizio, Dec 16 '16 at 13:02

Prepare html file and then convert to pdf. Swift 3.0 version:

func drawPDFUsingPrintPageRenderer(printPageRenderer: UIPrintPageRenderer) -> NSData! {
    let data = NSMutableData()
    UIGraphicsBeginPDFContextToData(data, CGRect.zero, nil)
    UIGraphicsBeginPDFPage()
    printPageRenderer.drawPage(at: 0, in: UIGraphicsGetPDFContextBounds())
    UIGraphicsEndPDFContext()
    return data
}

func exportHTMLContentToPDF(HTMLContent: String) {
    let printPageRenderer = CustomPrintPageRenderer()
    let printFormatter = UIMarkupTextPrintFormatter(markupText: HTMLContent)
    printPageRenderer.addPrintFormatter(printFormatter, startingAtPageAt: 0)
    let pdfData = drawPDFUsingPrintPageRenderer(printPageRenderer: printPageRenderer)
    let pdfFilename = getDocumentsDirectory().appendingPathComponent("nameOfPDFfile.pdf")

    pdfData?.write(to: pdfFilename, atomically: true)
    }
}

Anyway of doing it without using HTML and just using _swift_, for example like a **PrintDocument** in C# ? — Ketan Dubey, Jul 11 '17 at 13:35
Nice, by using HTML I can easily have my designer prepare that template for me. — jamone, Jul 30 '19 at 16:23

There are quite a few pods to create PDFS easily. I just used SimplePDF and it was a breeze.

I hope this helps someone.

I wrote a pod for creating PDF's using HTML Templates:

If the usage guide is not helpful, you could also have a look at the example project.

            for i in 1...render.numberOfPages {

                render.drawPage(at: i - 1, in: bounds)
            }

            UIGraphicsEndPDFContext();

            // 5. Save PDF file you can also save this file by using another button


            let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]

            filedata.write(toFile: "\(documentsPath)/myfile.pdf", atomically: true)

           }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.

// Button on view for show the file  in webview
