Download Fake Implementation

Example of arquitecture

Interactors. Between layers.

import Foundation

protocol DownloadAllShopsInteractor {
    func execute(onSuccess: @escaping (Shops) -> Void, onError: errorClosure)
    func execute(onSuccess: @escaping (Shops) -> Void)
}

Example of implementation

class DownloadAllShopsInteractorFakeImpl: DownloadAllShopsInteractor {
    func execute(onSuccess: @escaping (Shops) -> Void) {
        execute(onSuccess: onSuccess, onError: nil)
    }
    
    func execute(onSuccess: @escaping (Shops) -> Void, onError: errorClosure = nil) {
        let shops = Shops()
        
        for i in 0...10 {
            let shop = Shop(name: "Shop number \( i )")
            shop.address = "Address \( 1 )"
            
            shops.add(shop: shop)
        }
        
        OperationQueue.main.addOperation {
            onSuccess(shops)
        }
    }
    
    
}

Example of use

import UIKit

class ShopsViewController: UIViewController {
    
    var shops: Shops?
   
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let downloadShopsInteractor: DownloadAllShopsInteractor = DownloadAllShopsInteractorFakeImpl()
        
        downloadShopsInteractor.execute { (shops: Shops) in
            // todo OK
            for i in 1...10 {
            print("Name: " + shops.get(index: i).name)
            }
            }
