Populating tableview cells from JSON with Alamofire (Swift 2)

Question

I have the following code.

import UIKit
import Alamofire

class CheHappyTableViewController: UITableViewController,         


        

Answer 1

Your self.tableView.reloadData() line is outside the callback, meaning that it gets called straight away, before the data has been loaded. Try this:

func loadHappyHourElements(){

    let testhappyhour:HappyHour = HappyHour(title: "TEST", image: "TESST", description: "TEST", postedDate: "TEST")
    self.happyHours.append(testhappyhour)

    let url:String = "https://gist.githubusercontent.com/arianitp/036133ebb5af317a595c/raw/f134ec241ec3126bedd6debe5de371e3e01d225b/happyhours.json"
    Alamofire.request(.GET, url, encoding:.JSON).responseJSON
        { response in switch response.result {
        case .Success(let JSON):
            let response = JSON as! NSArray
            for item in response { // loop through data items
                let obj = item as! NSDictionary
                let happyhour = HappyHour(title:obj["title"] as! String, image:obj["image"] as! String, description:obj["description"] as! String, postedDate:obj["date"] as! String)
                self.happyHours.append(happyhour)
            }
            self.tableView.reloadData()

        case .Failure(let error):
            print("Request failed with error: \(error)")
            }
    }
}
