UITableView and Cells from Model Array - ios

Question

I'm stuck on something I don't quite understand as from a few tests, it looks like the generation of table cell is happening before but not as well after a page load and Alamofire request.
If you see below I'm trying to get it to where our museum's outbound shipments are viewed after referencing the pro:
import Alamofire
import SwiftyJSON
class ShipmentProSearchResultsTableViewController: UITableViewController {
var pronumber:String = ""
var shipments = [Shipment]()
typealias JSONStandard = [String: AnyObject]
override func viewDidLoad() {
super.viewDidLoad()
fetchShipments()
}
func fetchShipments() {
let parameters: Parameters = ["pro_number": pronumber]
let todoEndpoint: String = "OURHOST/shipments/api/details/pro"
Alamofire.request(todoEndpoint, method: .get, parameters: parameters)
.responseJSON { response in
if response.result.isSuccess{
let shipmentJSON : JSON = JSON(response.result.value!)
for (index, subJson):(String, JSON) in shipmentJSON{
let proNumber = subJson["proNumber"].int
let consigneeName = subJson["consignee"]["name"].string
let shipment = Shipment(proNumber: proNumber!, consigneeName: consigneeName!)
self.shipments.append(shipment)
}
print(self.shipments)
}else{
print("Could not get results")
}
}
}
// MARK: - Table view data source
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return shipments.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ShipmentCell", for: indexPath)
let shipment = shipments[indexPath.row]
cell.textLabel?.text = "Hello"
cell.detailTextLabel?.text = "\(shipment.proNumber)"
return cell
}
}
Now where I printed the self.shipments, I get the following results:
[OakRidgeArchaeologicalRepositoryDispatcher.Shipment(proNumber: 471008276, consigneeName: "A1 CHICAGO INSTITUTE OF THE ARTS")]
So I know the data is appropriately being passed to the model. I will also note that the Table View Cell Identifier in the storyboard is correctly set to ShipmentCell. But after the query, nothing pops up in my table.
I'm using Swift 4.

You should reload the tableView after updating source field.
func fetchShipments() {
let parameters: Parameters = ["pro_number": pronumber]
let todoEndpoint: String = "OURHOST/shipments/api/details/pro"
Alamofire.request(todoEndpoint, method: .get, parameters: parameters)
.responseJSON { response in
if response.result.isSuccess{
let shipmentJSON : JSON = JSON(response.result.value!)
for (index, subJson):(String, JSON) in shipmentJSON{
let proNumber = subJson["proNumber"].int
let consigneeName = subJson["consignee"]["name"].string
let shipment = Shipment(proNumber: proNumber!, consigneeName: consigneeName!)
self.shipments.append(shipment)
}
tableView.reloadData() //<-------add this.
print(self.shipments)
}else{
print("Could not get results")
}
}
}
