# canUndo

A Boolean value that indicates whether the manager has any actions to undo.

```
var canUndo: Bool { get }
```

## Discussion

<doc://com.apple.documentation/documentation/Swift/true> if the manager has any actions to undo, otherwise <doc://com.apple.documentation/documentation/Swift/false>.

The return value doesn’t mean you can safely invoke [`undo()`](/documentation/Foundation/UndoManager/undo()) or [`undoNestedGroup()`](/documentation/Foundation/UndoManager/undoNestedGroup())—you may have to close open undo groups first.
