PDFkit无法快速选择本地文件URL Download


我已经使用Alamofire实现了下载文件功能。文件下载成功，但是当我尝试在本地读取文件时，它总是给我Fatal error: Unexpectedly found nil while unwrapping an Optional value。如果我将粘贴本地文件链接复制到浏览器，则会打开文件或在Finder中打开文件。

在线错误： pdfView.document = PDFDocument(url: fileURL!)

响应本地文件位置：

/Users/abc/Library/Developer/CoreSimulator/Devices/4B6C2727-46AB-4797-8CBB-D5A897867013/data/Containers/Data/Application/C782E91D-9E63-4D1D-BBB3-2CD0414E6EA6/Documents/3602319458509320922.pdf

代码：

let fileType = (URL != nil) ? ".pdf" : ".png"

        DataProvider.main.downloadFile(url: String(describing: self.URL!), filetype: fileType, callback: { success, response in

            if !success || response == nil {
                return false
            }
            if((response as! String).hasSuffix("pdf")){

                print(response)
                let fileURL = Bundle.main.url(forResource: response as? String, withExtension: "pdf")
                pdfView.document = PDFDocument(url: fileURL!)


            }else if (FileManager.default.fileExists(atPath: (response as! String).removingPercentEncoding!) ){

                let fileURL = Bundle.main.url(forResource: response as? String, withExtension: "pdf")
                pdfView.document = PDFDocument(url: fileURL!)

            }
            return true
        })
