# DevicePickerSupportedAction

An environment value that indicates whether the current device supports device discovery.

## Declaration

```swift
struct DevicePickerSupportedAction
```

## Overview

Overview Access the action using the .devicePickerSupports key. Then call it as a function, passing the same browse descriptor and parameters you use to search for devices. struct SettingsView: View {

@Environment{\.devicePickerSupports} var myDevicePickerSupports     @Binding var showDevicePicker: Bool

var body: some View {         if myDevicePickerSupports(.applicationService("MyAppService"),                                   parameters: { .applicationService }) {             Button("Select A Device") {                 // Display a device picker.                 showDevicePicker = true             }         }     } }
