# GKDialogController

An object that provides the ability to present the dashboard in macOS games.

## Declaration

```swift
class GKDialogController
```

## Overview

Overview For macOS games, use a GKDialogController object to present the dashboard from which players can browse and manage their Game Center data. Initialize a new GKGameCenterViewController object, as you would for an iOS game, specifying the state and setting its delegate. Then get the singleton dialog controller using the shared() class method, or initialize a new GKDialogController object. To present the dashboard, set the parentWindow property to the window that should display the dashboard and then call the present(_:) method, passing the GKGameCenterViewController object. func presentAchievement() {     let viewController = GKGameCenterViewController(achievementID: "101")     viewController.gameCenterDelegate = self          let dialogController = GKDialogController.shared()     dialogController.parentWindow = NSApplication.shared.mainWindow     dialogController.present(viewController) } When the player closes the dashboard, GameKit calls the gameCenterViewControllerDidFinish(_:) delegate method. Implement this method to dismiss the shared dialog controller using the dismiss(_:) method. func gameCenterViewControllerDidFinish(_ gameCenterViewController: GKGameCenterViewController) {     // Dismiss the view controller.     let dialogController = GKDialogController.shared()     dialogController.dismiss(self) }
