# StoredIn

[![Swift Package Manager compatible](https://img.shields.io/badge/Swift%20Package%20Manager-compatible-brightgreen.svg)](https://github.com/apple/swift-package-manager)

`StoredIn` is a simple property wrapper library to store any value in anywhere.

## Installation

Please use the `Swift Package Manager`.

```swift

dependencies: [

    .package(url: "https://github.com/moriturus/StoredIn.git", .upToNextMajor(from: "1.0.0"))

]

```

## Usage

```swift

import StoredIn

// implement the `Store` where your data are saved.

final class SharedDictionary: Store {

    typealias Key = String

    

    var inner: [String: Any] = [:]

    

    func containsValue(forKey key: String) -> Bool {

        self.inner[key] != nil

    }

    

    func value(forKey key: String) -> S? where S : Storable {

        self.inner[key] as? S

    }

    

    func set(value: S, forKey key: String) where S : Storable {

        self.inner[key] = value

    }

}

let sharedDictionary = SharedDictionary()

struct Foo {

    @StoredIn(store: sharedDictionary, key: "key", default: 0, strategy: .default)

    var value: Int

}

var foo = Foo()

let x = foo.value // x == 0

foo.value = 1

sharedDictionary.inner["key"] as? Int == foo.value // true

```

## Strategy

- `default`

    - The default strategy. You can change stored value as many times as you need.

- `once`

    - You can store a value only once.
