# UnkeyedEncodingContainer

A type that provides a view into an encoder’s storage and is used to hold the encoded properties of an encodable type sequentially, without keys.

## Declaration

```swift
protocol UnkeyedEncodingContainer
```

## Overview

Overview Encoders should provide types conforming to UnkeyedEncodingContainer for their format.
