# yield()

Resume the task awaiting the next iteration point by having it return normally from its suspension point.

## Declaration

```swift
@discardableResult func yield() -> AsyncThrowingStream<Element, Failure>.Continuation.YieldResult where Element == ()
```

## Return Value

Return Value A YieldResult that indicates the success or failure of the yield operation.

## Discussion

Discussion Use this method with AsyncThrowingStream instances whose Element type is Void. In this case, the yield() call unblocks the awaiting iteration; there is no value to return. If you call this method repeatedly, each call returns immediately, without blocking for any awaiting consumption from the iteration.
