Instance Method


Asks the receiving responder to add and remove items from a command system.


func buildCommands(with builder: UICommandBuilder)



An object that you use to modify a command system for your app.


Override this method in your app delegate or view controller to receive a builder object. Use the builder to add and remove UICommand and UICommandGroup objects from your app's menu bar or context menus.

Where you override this method determines the command system that the builder updates. To add and remove items from the menu bar using the main command system, override buildCommands(with:) in your app delegate. To build a context menu using the context system, override this method in your view controller.
