About ApiKit

ApiKit helps you integrate with external REST APIs.

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

ApiKit has ApiEnvironment and ApiRoute models that can be used to model 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.

An ApiClient can then be used to fetch any ApiRoute from any ApiEnvironment and return a typed result.

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

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.

Getting started

The online documentation has a getting started guide to help you get started with ApiKit.

In ApiKit, you can either fetch raw URLRequests and handle the raw data, or create custom ApiEnvironment and ApiRoute types to model various APIs and return typed results.

For instance, with this TheMovieDb-specific ApiEnvironment:

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 this TheMovieDb-specific ApiRoute:

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 can now fetch movies like this:

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