SLazeKit is a framework providing models mapper and CoreData serializer for RESTful resources.

What's New

Release 0.3.0


Update to swift 5


Language License CocoaPods Carthage

SLazeKit is an easy to use Swift restful collection of extensions and classes. Don't spend hours writing your code to map your rest api request into models and coredata serialization. Stop wasting your time!

SLazeKit allows you:

  • map your models by Codable protocol
  • serialize CoreData models from API response with SLazeCoreData or any other extension
  • fast and simple extend your models with API & CoreData

  • This request will use default configuration scheme.
  • The type ResponseModel is a result object type for result callback argument. If you want to decode array you simple execute method on [ResponseModel] type.
  • The error indicates why the request failed, or nil if the request was successful. it include EntityMaping errors, url preparation error and so on. If a response from the server is received, regardless of whether the request completes successfully or fails, the response parameter contains that information.
  • The response provides tuple with HTTPURLResponse object and the data returned by the server.
  • The request handler is executed on the URLSession delegate queue.
class func getRequest(for modelId: String, success: @escaping ((Model?) ->()), failure: (() ->())? = nil) throws {
    let _ = ResponseModel.get(path: PathPattern.model.patternToPath(with: ["modelId":modelId])) { (response, result, error) in
    guard response?.urlResponse?.statusCode == 200 && error == nil else {
    success(try result?.serialized(SLazeKit.newBackgroundContext()) as? Model)

If ResponseModel conforms to EntityMapping protocol it will be synchronize with CoreData. That means if mode object already exist it will update it or create new instance and fill NSManagedObject with response data. You can serialize your response to receive CoreData object on given context by:

try result?.serialized(NSManagedObjectContext) as? Model)

Calling this method simple query NSManagedObject which was synchronize before by given object id.

Models example

Simple Object.swift Advance Model.swift

In case of any other configuration you can use Laze

//Laze<C: LazeConfiguration, D: Decodable>
Laze<Default, ResponseModel>.get( // Default configuration, result in ResponseModel model
SLazeKit<Default>.get( // Default configuration, no result model
ResponseModel.get( // Default configuration, result in ResponseModel model

🔧 Installation


Add the line pod "SLazeKit" to your Podfile


Add the line github "shial4/SLazeKit" to your Cartfile


Clone the repo and drag the folder SLazeKit into your Xcode project.

Swift Package Manager:

Add the line .package(url: "", from: "0.2.1"), to your Package.swift

Swift Package Manager in your iOS Project: This project demonstrates a working method for using Swift Package Manager (SPM) to manage the dependencies of an iOS project.

💊 Usage

For positive experience, you should configure SLazeKit at first.

SLazeKit in default configuration uses Default class which conforms to LazeConfiguration protocol. I do recommand extend Default configuration. Moreover , If you have more then one API in your project. You can create as many as needed configurations schemes by creating your own object which do conform to LazeConfiguration protocol.

import SLazeKit

extension Default {
    //Provide base path for your API requests.
    open class var basePath: String? { return "" }
    //Additional you can set port for your requests.
    open class var basePort: Int? { return 8040  }
    //You can provide your own instance of JSONDecoder.
    open class var decoder: JSONDecoder { return JSONDecoder() }
    //You can customize instance of URLSession in here.
    open class var urlSession: URLSession { return URLSession.shared }
    //If you feel like to set header dor requests do it in here.
    open class func setup(_ request: URLRequest) -> URLRequest {
        var request: URLRequest = request
        request.setValue("Your token", forHTTPHeaderField: "X-Access-Token")
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")
        return request
    //If you feel like to monitor response. You can do it in here.
    open class func handle(_ response: HTTPURLResponse?) {
        if response?.statusCode == 401 {
    /// Method dedicated to be use for synchronize object into persisten store
    /// - Parameter obj: encoded object
    /// - Throws: error occured during the process
    open static func synchronize(_ obj: Any) {}
