Installation

Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

NetworkRequester supports only SPM and adding it as a dependency is done just by including the URL into the dependencies value of your Package.swift.

dependencies: [
    .package(
        url: "https://github.com/igashev/NetworkRequester.git",
        .upToNextMajor(from: "1.2.0")
    )
]

Or by using the integrated tool of Xcode.

Usage

Building requests

NetworkRequester provides a very easy way to build a request using URLRequestBuilder.

// Creating a builder
let requestBuilder = URLRequestBuilder(
    environment: Environment.production,
    endpoint: UsersEndpoint.users,
    httpMethod: .get,
    httpHeaders: [
        .json, 
        .authorization(bearerToken: "secretBearerToken")
    ],
    httpBody: nil,
    queryParameters: nil
)

Calling requests

There are two options with which to make the actual network request.

The first option is using plain URLRequest.

struct User: Decodable {
    let name: String
}

struct BackendError: DecodableError {
    let errorCode: Int
    let localizedError: String
}

let url = URL(string: "https://amazingapi.com/v1/users")!
let urlRequest = URLRequest(url: url)

let caller = AsyncCaller(decoder: JSONDecoder())
let user: User = try await caller.call(
    using: urlRequest, 
    errorType: BackendError.self
)

The second option is using URLRequestBuilder.

struct User: Decodable {
    let name: String
}

struct BackendError: DecodableError {
    let errorCode: Int
    let localizedError: String
}

let requestBuilder = URLRequestBuilder(
    environment: "https://amazingapi.com",
    endpoint: "v1/users",
    httpMethod: .get,
    httpHeaders: [
        .json, 
        .authorization(bearerToken: "secretBearerToken")
    ],
    httpBody: nil,
    queryParameters: nil
)

let caller = AsyncCaller(decoder: JSONDecoder())
let user: User = try await caller.call(
    using: requestBuilder, 
    errorType: BackendError.self
)

Take into account that when a response data is expected, a type that conforms to Encodable should be specified as Output. Otherwise Void.
