# fileImporter(isPresented:allowedContentTypes:allowsMultipleSelection:onCompletion:) Presents a system dialog for allowing the user to import multiple files. ``` nonisolated func fileImporter(isPresented: Binding, allowedContentTypes: [UTType], allowsMultipleSelection: Bool, onCompletion: @escaping (Result<[URL], any Error>) -> Void) -> some View ``` ## Parameters `isPresented` A binding to whether the dialog should be shown. `allowedContentTypes` The list of supported content types which can be imported. `allowsMultipleSelection` Whether the importer allows the user to select more than one file to import. `onCompletion` A callback that will be invoked when the operation has succeeded or failed. To access the received URLs, call `startAccessingSecurityScopedResource`. When the access is no longer required, call `stopAccessingSecurityScopedResource`. - result: A `Result` indicating whether the operation succeeded or failed. ## Discussion In order for the dialog to appear, `isPresented` must be `true`. When the operation is finished, `isPresented` will be set to `false` before `onCompletion` is called. If the user cancels the operation, `isPresented` will be set to `false` and `onCompletion` will not be called. > Note: This dialog provides security-scoped URLs. > Call the ``startAccessingSecurityScopedResource`` method to access or bookmark > the URLs, and the ``stopAccessingSecurityScopedResource`` method > to release the access. For example, a button that allows the user to choose multiple PDF files for the application to combine them later, might look like this: ``` struct PickPDFsButton: View { @State private var showFileImporter = false var handlePickedPDF: (URL) -> Void var body: some View { Button { showFileImporter = true } label: { Label("Choose PDFs to combine", systemImage: "doc.circle") } .fileImporter( isPresented: $showFileImporter, allowedContentTypes: [.pdf], allowsMultipleSelection: true ) { result in switch result { case .success(let files): files.forEach { file in // gain access to the directory let gotAccess = file.startAccessingSecurityScopedResource() if !gotAccess { return } // access the directory URL // (read templates in the directory, make a bookmark, etc.) handlePickedPDF(file) // release access file.stopAccessingSecurityScopedResource() } case .failure(let error): // handle error print(error) } } } } ``` > Note: Changing `allowedContentTypes` or `allowsMultipleSelection` > while the file importer is presented will have no immediate effect, > however will apply the next time it is presented.
