# defaultItemIdentifiers

A required list of identifiers for items that you want to appear in the Touch Bar after instantiating it.

## Declaration

```swift
var defaultItemIdentifiers: [NSTouchBarItem.Identifier] { get set }
```

## Discussion

Discussion Always specify this property for an NSTouchBar object, even if you elect to make the bar noncustomizable. The system: Shows this list’s items by default when the system displays the bar. Includes a preconfigured bar, containing these items, in the associated customization UI (when you have assigned the bar a customizationIdentifier property value); the user can drag the default bar into the Touch Bar, should they want to return to the default configuration. The system archives this property.
