# PlaygroundKeyValueStore

A data storage container you use to persist information across different sessions.

## Declaration

```swift
class PlaygroundKeyValueStore
```

## Overview

Overview The key-value store is available only in Swift Playgrounds and is persistent only in playground books. The example below sets the value of the key “animal” in the playground key-value store to “Llama” and then retrieves the value of that key back from the key-value store. // Store a value. PlaygroundKeyValueStore.current.keyValueStore["animal"] = .string("Llama")

// Retreive that same value.	  var theAnimal: String? = nil if let keyValue = PlaygroundKeyValueStore.current.keyValueStore["animal"],     case .string(let animalType) = keyValue {     theAnimal = animalType }
