# DropFirstSequence

A sequence that lazily consumes and drops n elements from an underlying Base iterator before possibly returning the first available element.

## Declaration

```swift
@frozen struct DropFirstSequence<Base> where Base : Sequence
```

## Overview

Overview The underlying iterator’s sequence may be infinite.
