Now i'm using the below code and it's working properly var mediaBox = CGRect(x: 0, y: 0, width: 1000, height: 1000)     let mutableData = CFDataCreateMutable(nil, 0)!     let dataConsumer = CGDataConsumer.init(data: mutableData)!     let context = CGContext.init(consumer: dataConsumer, mediaBox: &mediaBox, nil) context?.beginPage(mediaBox: nil) some drawing operations context.endPage() after this i'm getting the file location from the user and saving the pdf file that location do {           try (mutableData as NSData).write(to: location, options: .atomic)         } catch {           print(error)         }
