Question

In Swift, I'm trying to generate a pdf version of a collectionView, and save that PDF to the temporary directory. However, I'm not sure if I'm doing it right, or actually even saving anything. Here's my code:

        func createPdfFromView(aView: UICollectionView, saveToDocumentsWithFileName fileName: String)
        {
            let pdfData = NSMutableData()
       
       
            UIGraphicsBeginPDFContextToData(pdfData, gridView.bounds, nil)
            UIGraphicsBeginPDFPage()
       
            guard let pdfContext = UIGraphicsGetCurrentContext() else { return }
       
            aView.layer.render(in: pdfContext)
            UIGraphicsEndPDFContext()
       
            let fileName = sampleClass.sampleStruct.samplePDF.rawValue
            let template = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(fileName)
       

                debugPrint(fileName)
                pdfData.write(toFile: String (describing: template), atomically: true)
        }
   how can I do this?
