Cannot retrieve image from Firebase into TableViewCell - ios

Question

I just began to learn Firebase a week ago, but right now I am facing a problem of not able to load image from Firebase to my TableViewCell. I can retrieve data such as text information and the URL of the image from Firebase Realtime Database but not able to make use of those URL in order to fire up image on the TableViewCell. May you all help me identify the problems? I can retrieve everything such as text information as well as the image URL but how can I make the image pop up on the cell? All your help would be highly appreciate!
This is the ViewController that responsible to display the TableViewCell
import UIKit
import Firebase
import FirebaseStorage
class NewsFeedViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var rubthort:String = ""
var linkRub:String?
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arrItem.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "mycell", for: indexPath) as! NewsFeed
// textlabel
// detailtextlabel
cell.textLabel?.text = arrItem[indexPath.row].name
cell.detailTextLabel?.text = arrItem[indexPath.row].price
//cell.imageView?.image = UIImage(named: "flower")
// Get image
let id = RetrieveData()
if let imageLink = self.linkRub {
let url = URL(string: imageLink)
//let data = NSData(contentsOf: url!)
URLSession.shared.dataTask(with: url!) { (data, response, error) in
// download hit an error so return out
if error != nil {
print(error)
return
}
DispatchQueue.main.async {
cell.imageView?.image = UIImage(data: data!)
}
}.resume()
}
return cell
}
let ref = Database.database().reference()
// Array of PlasticItem
var arrItem = [RetrieveData]()
#IBOutlet weak var tblView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
retrieveData()
} // Ends of viewDidLoad
func retrieveData() {
// Getting a node from database
let retRef = ref.child("item/electronic")
// Observing data changes
retRef.observe(DataEventType.value) { (dataSnapshot) in
// Remove array item everytime there is a new reference to the data in Firebase
self.arrItem.removeAll()
// Check if there are any children or second object inside the parent object
if dataSnapshot.childrenCount > 0 {
// Loop over all children's object
for post in dataSnapshot.children.allObjects as! [DataSnapshot] {
let object = post.value as! [String: Any]
let getName = object["name"] as! String
let getPrice = object["price"] as! String
let getImage = object["itemURL"] as! String
print(getName)
print(getPrice)
print(getImage)
self.linkRub = getImage
self.arrItem.append(RetrieveData(cat: "", name: getName, price: getPrice, rub: getImage))
}
self.tblView.reloadData()
}// Ends of if statement
else if dataSnapshot.childrenCount == 0{
print("No Data Found")
}
} // Ends of retRef.observe
} // Ends of retrieveData()
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destination.
// Pass the selected object to the new view controller.
}
*/
}
This is the model struct
import Foundation
import UIKit
struct RetrieveData{
var cat: String
var name: String
var price: String
var rub: String?
init(){
self.cat = ""
self.name = ""
self.price = ""
self.rub = ""
}
init(cat:String, name:String, price:String, rub: String){
self.cat = cat
self.name = name
self.price = price
self.rub = rub
}
}
