Convert PDF To Base64 in SwiftUI – Ios swift

I am fetching PDF data. It provides me URL, and when I am converting it to base64. This is what I am getting:

The file “file.pdf” couldn’t be opened because you don’t have permission to view it.

I am not getting why is it giving this. This is how I am getting the pdf file url:

 @State var openPDF = false
 @State var fileName = ""
 @State var pdfFile : URL?

  var body: some View {

   Button {
        self.openPDF.toggle()
    }, label {
         
          Text("Add Attachment")
     }.fileImporter(isPresented: $vm.openPDF, allowedContentTypes: [.pdf]) { result in
                    
            do {

                let fileURL = try result.get()
                print(fileURL)

                self.fileName = fileURL.lastPathComponent

                self.pdfFile = fileURL
              } catch {
                    print("error getting documents")
                    print(error.localizedDescription)
                   }
             }
}

An this is how I am converting it to base64:

    do {
            
        let filePath = pdfFile
        let fileData = try Data.init(contentsOf: filePath!)
        let fileStream:String = fileData.base64EncodedString()
        print(fileStream)
    } catch {
        print("error")
        print(error.localizedDescription)
   }

In this do-catch, it is giving the error that "this file could not be opened because you don’t have permission.

    Do this to convert PDF to Base64 String:

    fileapp.startAccessingSecurityScopedResource() {
            defer {
                DispatchQueue.main.async {
                    fileapp.stopAccessingSecurityScopedResource()
                }
            }
            
            do {
                
                let fileData = try Data.init(contentsOf: fileapp)
                let fileStream:String = fileData.base64EncodedString()
                print(fileStream)
                base64PDF = fileStream
            } catch {
                print("error")
                print(error.localizedDescription)
            }
        }

    My Code for converting PDF to Base64String
    Here fileName is State variable and base64PDF is also a State variable

    I have used If condition before fileurl because it is giving error

        Text(fileName)
        .fileImporter(isPresented: $isImporting, allowedContentTypes: [.pdf]) { result in
            do{
                let fileUrl = try result.get()
                self.fileName = fileUrl.lastPathComponent
                print(fileUrl)
                
                if fileUrl.startAccessingSecurityScopedResource() {
                    defer {
                        DispatchQueue.main.async {
                            fileUrl.stopAccessingSecurityScopedResource()
                        }
                    }
                    
                    do {
                        
                        let fileData = try Data.init(contentsOf: fileUrl)
                        let fileStream:String = fileData.base64EncodedString()
                        print(fileStream)
                        base64PDF = fileStream
                        print(base64PDF)
                        
                    } catch {
                        print("error")
                        print(error.localizedDescription)
                    }
                }
                
            }catch{
                print("Error reading docs")
                print(error.localizedDescription)
            }
        }
