Protocol Oriented Generic Network Layer example with Alamofire and Swift4
Usage is so simple:
Just create Request Class and implement the Requestable protocol, in example project i created UserRequest to fetch user info from Github API
Requestable protocol will force you to implement some usefull functions as shown below.
final class UserRequest: Requestable {
typealias ResponseType = UserResponse
private var userName : String
init(userName:String) {
self.userName = userName
}
var baseUrl: URL {
return URL(string: "https://api.github.com/")!
}
var endpoint: String {
return "users/\(self.userName)"
}
var method: Network.Method {
return .get
}
var query: Network.QueryType {
return .path
}
var parameters: [String : Any]? {
return nil
}
var headers: [String : String]? {
return defaultJSONHeader
}
var timeout: TimeInterval {
return 30.0
}
var cachePolicy: NSURLRequest.CachePolicy {
return .reloadIgnoringLocalAndRemoteCacheData
}
}
Meanwhile you should create also responseModel and implement the Codable protocol your model. Example project shows UserResponse as shown below:
And Thats all! You do not have to decode the response. Network class does it for you.. :)
public struct UserResponse: Codable {
public let userName: String?
public let userId: Int?
public let avatarUrl: String?
enum CodingKeys: String, CodingKey {
case userName = "login", userId = "id", avatarUrl = "avatar_url"
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Assign request instance to cancel in future
// Just call cancel() to assigned instance
_ = Network.request(req: UserRequest(userName: "ahmetkgunay")) { (result) in
switch result {
case .success(let userResponse):
print(userResponse)
case .cancel(let cancelError):
print(cancelError!)
case .failure(let error):
print(error!)
}
}
}
