# shouldBeRequiredToFail(by:)

Overridden to indicate that the receiver should be required to fail by the specified gesture recognizer.

## Declaration

```swift
func shouldBeRequiredToFail(by otherGestureRecognizer: UIGestureRecognizer) -> Bool
```

## Parameters

- `otherGestureRecognizer`: An instance of a subclass of UIGestureRecognizer.

## Return Value

Return Value true to set up the failure requirement; otherwise, false.

## Discussion

Discussion Overriding this method allows a subclass to define a class-wide failure requirement.
