# gestureRecognizer(_:shouldRecognizeSimultaneouslyWith:)

Asks the delegate if two gesture recognizers should be allowed to recognize gestures simultaneously.

## Declaration

```swift
optional func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool
```

## Parameters

- `gestureRecognizer`: An instance of a subclass of the abstract base class doc://com.apple.uikit/documentation/UIKit/UIGestureRecognizer. This is the object sending the message to the delegate.
- `otherGestureRecognizer`: An instance of a subclass of the abstract base class doc://com.apple.uikit/documentation/UIKit/UIGestureRecognizer.

## Mentioned in

Allowing the simultaneous recognition of multiple gestures

## Return Value

Return Value true to allow both gestureRecognizer and otherGestureRecognizer to recognize their gestures simultaneously. The default implementation returns false—no two gestures can be recognized simultaneously.

## Discussion

Discussion This method is called when recognition of a gesture by either gestureRecognizer or otherGestureRecognizer would block the other gesture recognizer from recognizing its gesture. Note that returning true is guaranteed to allow simultaneous recognition; returning false, on the other hand, is not guaranteed to prevent simultaneous recognition because the other gesture recognizer’s delegate may return true.
