# dropFirst(_:)

Omits a specified number of elements from the base asynchronous sequence, then passes through all remaining elements.

## Declaration

```swift
func dropFirst(_ count: Int = 1) -> AsyncDropFirstSequence<Self>
```

## Parameters

- `count`: The number of elements to drop from the beginning of the sequence. count must be greater than or equal to zero.

## Return Value

Return Value An asynchronous sequence that drops the first count elements from the base sequence.

## Discussion

Discussion Use dropFirst(_:) when you want to drop the first n elements from the base sequence and pass through the remaining elements. In this example, an asynchronous sequence called Counter produces Int values from 1 to 10. The dropFirst(_:) method causes the modified sequence to ignore the values 1 through 3, and instead emit 4 through 10: for await number in Counter(howHigh: 10).dropFirst(3) {     print(number, terminator: " ") } // Prints "4 5 6 7 8 9 10 " If the number of elements to drop exceeds the number of elements in the sequence, the result is an empty sequence.
