About ApiKit

ApiKit is a Swift library that makes it easy to integrate with any external REST APIs.

ApiKit has an ApiClient protocol that can fetch any URLRequest and decode the data to any Decodable type. It's implemented by URLSession so you can either use URLSession.shared or create your own custom service.

ApiKit has an ApiEnvironment and ApiRoute model that can be used to model the available environments and routes for any REST API, such as the base URL of a certain API environment, the URL of a certain route, which parameters and headers to send etc.

Any ApiClient can then fetch any ApiRoute from any ApiEnvironment and automatically have the result decoded to any Decodable type.

Installation

ApiKit can be installed with the Swift Package Manager:

https://github.com/danielsaidi/ApiKit.git

If you prefer to not have external dependencies, you can also just copy the source code into your app.

Supported Platforms

ApiKit supports iOS 13, macOS 11, tvOS 13 and watchOS 6.

Getting started

Implementing API integrations with ApiKit is very easy. You can either fetch raw URLRequests and handle the raw data, or create custom ApiEnvironment and ApiRoute types to model various APIs.

For instance, with a TheMovieDb-specific environment:

enum TheMovieDbEnvironment: ApiEnvironment {

    case production(apiKey: String)

    public var url: String {
        switch self {
        case .production: return "https://api.themoviedb.org/3"
        }
    }

    public var headers: [String: String]? { nil }

    public var queryParams: [String: String]? {
        switch self {
        case .production(let key): return ["api_key": key]
        }
    }
}

and a TheMovieDb-specific route:

enum Route: ApiRoute {

    case movie(id: Int)
    
    public var path: String {
        switch self {
        case .movie(let id): return "movie/\(id)"
        }
    }

    public var queryParams: [String: String]? {
        switch self {
        case .movie: return nil
        }
    }

    public var httpMethod: HttpMethod { .get }
    public var headers: [String: String]? { nil }
    public var formParams: [String: String]? { nil }
    public var postData: Data? { nil }
}

we could easily fetch movies like this:

let client = URLSession.shared
let environment = TheMovieDb.Environment.production("API_KEY") 
let route = TheMovieDb.Route.movie(id: 123) 
let movie: TheMovieDb.Movie = try await client.fetchItem(at: route, in: environment)
