# contains(_:)

Returns a Boolean value that indicates whether the asynchronous sequence contains the given element.

## Declaration

```swift
func contains(_ search: Self.Element) async rethrows -> Bool
```

## Parameters

- `search`: The element to find in the asynchronous sequence.

## Return Value

Return Value true if the method found the element in the asynchronous sequence; otherwise, false.

## Discussion

Discussion In this example, an asynchronous sequence called Counter produces Int values from 1 to 10. The contains(_:) method checks to see whether the sequence produces the value 5: let containsFive = await Counter(howHigh: 10)     .contains(5) print(containsFive) // Prints "true"
