# fileExporter(isPresented:items:contentTypes:onCompletion:onCancellation:)

Presents a system dialog allowing the user to export a collection of Transferable items to files on disk.

## Declaration

```swift
nonisolated func fileExporter<C, T>(isPresented: Binding<Bool>, items: C, contentTypes: [UTType] = [], onCompletion: @escaping (Result<[URL], any Error>) -> Void, onCancellation: @escaping () -> Void = { }) -> some View where C : Collection, T : Transferable, T == C.Element

```

## Parameters

- `isPresented`: A binding to whether the dialog should be shown.
- `items`: Collection of values to be saved on disk.
- `contentTypes`: The content types to use for the exported files. If empty, SwiftUI uses the content types from the transferRepresentation property provided for Transferable conformance.
- `onCompletion`: A callback that will be invoked when the operation has succeeded or failed.
- `onCancellation`: A callback that will be invoked if the user cancels the operation.

## Discussion

Discussion In order for the dialog to appear, isPresented must be set to 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 onCancellation will be called. For example, a button that exports a collection of photos might look like this: struct ExportPhotosButton: View {     @State private var isExporterPresented = false     var photos: [Photo]

var body: some View {         Button("Export Photos") {             isExporterPresented = true         }         .fileExporter(             isPresented: $isExporterPresented,             items: photos         ) { result in             switch result {             case .success(let urls):                 urls.forEach { print("Saved to \($0)") }             case .failure(let error):                 print(error)             }         }     } }

struct Photo: Transferable { ... } To further configure the dialog’s appearance and behavior, use these view modifiers: fileDialogDefaultDirectory(_:), fileDialogConfirmationLabel(_:), fileDialogMessage(_:), fileDialogBrowserOptions(_:), fileExporterFilenameLabel(_:), and fileDialogCustomizationID(_:).
