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?
