# complete(_:)

Invokes completion in a text view.

## Declaration

```swift
func complete(_ sender: Any?)
```

## Parameters

- `sender`: The control sending the message. May be nil.

## Discussion

Discussion By default invoked using the F5 key, this method provides users with a choice of completions for the word currently being typed. May be invoked programmatically if autocompletion is desired by a client of the text system. You can change the key invoking this method using the text system’s key bindings mechanism; see “Text System Defaults and Key Bindings” for an explanation of the procedure. The delegate may replace or modify the list of possible completions by implementing textView(_:completions:forPartialWordRange:indexOfSelectedItem:). Subclasses can control the list by overriding completions(forPartialWordRange:indexOfSelectedItem:).
