This is a Swift package for working with [GeoJSON](https://geojson.org) data. It contains necessary types conforming to `Codable` for easy de-/encoding of data.

The implementation of this package aims to follow the specification defined in [RFC 7946](https://tools.ietf.org/html/rfc7946).

## Usage

You can give this package a quick spin by cloning the repository and running `swift run --repl` inside it.

### Encoding

Create a `FeatureCollection` or just a single `Feature` to create some GeoJSON data. 

```swift

let features = FeatureCollection(features: [

    Feature(

        geometry: .point(Point(longitude: 125.6, latitude: 10.1)),

        properties: [

            "name": "Dinagat Island"

        ]

    )

])

let json = try JSONEncoder().encode(features)

```

### Decoding

It works the same way in the other direction. Use a standard `JSONDecoder` to decode GeoJSON data into a fitting type.

```swift

let features = try JSONDecoder().decode(FeatureCollection.self, from: json)

```

If you don't know if the data to decode is a `Feature` or `FeatureCollection`, decode a value of type `GeoJSONDocument`, which handles 

both.

```swift

let document = try JSONDecoder().decode(GeoJSONDocument.self, from: json)

switch document {

case .feature(let feature):

    // ...

case .featureCollection(let featureCollection):

    // ...

}

```
