## Overview

This library helps you to use your custom type that conform to `Codable` protocol with Firebase. Here's an example of model:

```swift
struct Model: Codable {
    let stringExample: String
    let booleanExample: Bool
    let numberExample: Double
    let dateExample: Date
    let arrayExample: [String]
    let nullExample: Int?
    let objectExample: [String: String]
}
```

And this is how you would encode it with [Firebase Firestore](https://firebase.google.com/products/firestore/):

```swift
import Firebase
import CodableFirebase

let model: Model // here you will create an instance of Model
let docData = try! FirestoreEncoder().encode(model)
Firestore.firestore().collection("data").document("one").setData(docData) { err in
    if let err = err {
        print("Error writing document: \(err)")
    } else {
        print("Document successfully written!")
    }
}
```

And this is how you would decode the same model with [Firebase Firestore](https://firebase.google.com/products/firestore/):

```swift
Firestore.firestore().collection("data").document("one").getDocument { (document, error) in
    if let document = document {
        let model = try! FirestoreDecoder().decode(Model.self, from: document.data())
        print("Model: \(model)")
    } else {
        print("Document does not exist")
    }
}
```
