Importing the selected file from DocumentPicker into the application [SwiftUI]

Question

I want to take the path of the folder or file I selected from Document Picker and move it to the "Folder" of my own application with FileManager. However, I am getting this error.

I want to save an image that I choose to the "Folder" path of my own application.

Error:

“Documents” couldn’t be moved because you don’t have permission to access “Documents”.

I solved this error with these codes. However, I'm still having permission issues.

func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) {
  
    guard url.startAccessingSecurityScopedResource() else {
        // Handle denied access
        return
    }
    defer { url.stopAccessingSecurityScopedResource() }
    
    let fileURL = url
    print("url: \(fileURL)")
    
    fileContent = fileURL
}

When I check the code with breakpoint, there is still return in guard let and the process terminates.

DocumentPicker:

struct DocumentPicker: UIViewControllerRepresentable {
    
    @Binding var fileContent: URL
    
    func makeCoordinator() -> DocumentPickerCoordinator {
        return DocumentPickerCoordinator(fileContent: $fileContent)
    }
    
    func makeUIViewController(context: UIViewControllerRepresentableContext<DocumentPicker>) -> UIDocumentPickerViewController {
        let controller: UIDocumentPickerViewController
        controller = UIDocumentPickerViewController(forOpeningContentTypes: [.text, .pdf, .folder, .jpeg, .png, .gif, .exe, .data], asCopy: true)
        controller.delegate = context.coordinator
        return controller
    }
    
    func updateUIViewController(_ uiViewController: UIDocumentPickerViewController, context: UIViewControllerRepresentableContext<DocumentPicker>) {
    }
}


class DocumentPickerCoordinator: NSObject, UIDocumentPickerDelegate, UINavigationControllerDelegate {
    
    @Binding var fileContent: URL
    
    init(fileContent: Binding<URL>) {
        _fileContent = fileContent
    }
    
    func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) {
  
        
        guard url.startAccessingSecurityScopedResource() else {
            // Handle denied access
            return
        }
        defer { url.stopAccessingSecurityScopedResource() }
        
        let fileURL = url
        print("url: \(fileURL)")
        
        fileContent = fileURL
    }
}
