# fileImporter(isPresented:allowedContentTypes:onCompletion:) Presents a system dialog for allowing the user to import an existing file. ``` nonisolated func fileImporter(isPresented: Binding, allowedContentTypes: [UTType], onCompletion: @escaping (Result) -> 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. `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, an application can have a button that allows the user to choose the default directory with document templates loaded on every launch. Such a button might look like this: ``` struct PickTemplatesDirectoryButton: View { @State private var showFileImporter = false var onTemplatesDirectoryPicked: (URL) -> Void var body: some View { Button { showFileImporter = true } label: { Label("Choose templates directory", systemImage: "folder.circle") } .fileImporter( isPresented: $showFileImporter, allowedContentTypes: [.directory] ) { result in switch result { case .success(let directory): // gain access to the directory let gotAccess = directory.startAccessingSecurityScopedResource() if !gotAccess { return } // access the directory URL // (read templates in the directory, make a bookmark, etc.) onTemplatesDirectoryPicked(directory) // release access directory.stopAccessingSecurityScopedResource() case .failure(let error): // handle error print(error) } } } } ``` > Note: Changing `allowedContentTypes` while the file importer is > presented will have no immediate effect, however will apply the next > time it is presented.
