# textShouldBeginEditing(_:)

Requests permission to begin editing text.

```
func textShouldBeginEditing(_ textObject: NSText) -> Bool
```

## Parameters

`textObject`

The text object requesting permission to begin editing.

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if the text object should proceed to make changes. If the delegate returns <doc://com.apple.documentation/documentation/Swift/false>, the text object abandons the editing operation.

## Discussion

The default behavior of this method is to return the value obtained from [`control(_:textShouldBeginEditing:)`](/documentation/AppKit/NSControlTextEditingDelegate/control(_:textShouldBeginEditing:)), unless the delegate doesn’t respond to that method, in which case it returns <doc://com.apple.documentation/documentation/Swift/true>, thereby allowing text editing to proceed.

This method is invoked to let the [`NSTextField`](/documentation/AppKit/NSTextField) respond to impending changes to its text. This method’s default behavior is to send [`control(_:textShouldBeginEditing:)`](/documentation/AppKit/NSControlTextEditingDelegate/control(_:textShouldBeginEditing:)) to the receiver’s delegate (passing the receiver and `textObject` as parameters).
