Swift - tableviewcell returns empty using custom cell - ios

Question

I am new to swift programming and would need some help to check what is wrong in my tableviewcell. I have tried alot of great suggestions on stackoverflow.( make sure your outlets are connected, set delegate and datasource of your tableview to self)
This is my ViewController:
import UIKit
class CharacterViewController: UIViewController, UITableViewDataSource, UITableViewDelegate , APIControllerProtocol {
#IBOutlet weak var CharacterInfoView: UITableView!
var apiController:APIController!
var dataArray: [[String:Any]]?
var processcharacter= [CharacterListModel]()
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor=UIColor.white
self.CharacterInfoView.estimatedRowHeight = 44
self.CharacterInfoView.rowHeight = UITableViewAutomaticDimension
self.CharacterInfoView.dataSource = self
self.CharacterInfoView.delegate = self
apiController = APIController()
apiController.delegate=self
self.navigationItem.title = "Character"
self.view.showLoading()
apiController.getCharacterData{ (statusCode, data, response, error) -> () in
self.view.stopLoading()
if(statusCode == nil)
{
self.view.showServiceNotAvailableMessage(self)
}
if !(error == nil)
{
self.view.showServiceNotAvailableMessage(self)
}
if statusCode == 200
{
do
{
self.processcharacter= CharacterListData.processData(data: data)
self.CharacterInfoView.reloadData()
}
catch(_ as NSError)
{
}
}
else
{
return
}
}
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if self.dataArray == nil
{
return 0
}
else
{
return processcharacter.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier:"Cell", for:indexPath) as! CharacterTableViewCell
var processcharacters= processcharacter[indexPath.row]
cell.location.text = processcharacters.location
cell.name.text = processcharacters.name
cell.characterID.text = processcharacters.characterID
cell.time.text = processcharacters.lastlocatedtime
if wecares.sos == true {
processcharacters.imagebutton = UIImage(named: "sos_icon")!
}
else{
processcharacters.imagebutton = UIImage(named: "null_button")!
}
cell.button.image = processcharacters.imagebutton
return cell
}
func reachabilityChanged(_ status: Bool) {
}
}
This is my subclass for my ViewController:
import Foundation
class CharacterListDataHelper: NSObject {
static func processData(data: AnyObject?) -> [CharacterListModel]
{
var modelList:[CharacterListModel] = [CharacterListModel]()
let darr = try? JSONSerialization.jsonObject(with: data! as! Data, options: .mutableLeaves) as! [[String:Any]]
var dataModel:CharacterListModel
for obj in darr!
{
dataModel = CharacterListModel()
dataModel.location = obj["playerLocation"] as! String
dataModel.name = obj["playerName"] as! String
dataModel.characterID= obj["playerID"] as! String
dataModel.lastlocatedtime = obj["lastUpdatedTime"] as! String
}
modelList.append(dataModel)
}
return modelList
}
}
This is my Model:
import Foundation
struct CharacterListModel {
var name: String?
var characterID: String?
var location: String?
var lastlocatedtime: String?
var imagebutton: UIImage?
var sos: Bool?
}
This is my TableViewCell:
class CharacterTableViewCell: UITableViewCell {
#IBOutlet weak var name: UILabel!
#IBOutlet weak var characterID: UILabel!
#IBOutlet weak var location: UILabel!
#IBOutlet weak var lastlocatedtime: UILabel!
#IBOutlet weak var button: UIImageView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
Thanks in advance!

Don't fetch data in viewDidLoad() method. Fetch in viewWillAppear and reload after getting data.
