UITableView is not showing up on physical device deployment - ios

Question

I created a UITableView and fed it some data using code.
While running the application on Xcode simulator it works fine but when I deploy it on physical device, the UITableView is not visible.
Image - 1 (Simulator)
Image - 2 (Device)
Below is my Code:
import UIKit
class OTCMedicines: UIViewController, UITableViewDelegate, UITableViewDataSource{
#IBOutlet weak var tableView: UITableView!
struct Med {
var name:String
var detail:String
var imageName:String
var image: UIImage {
get {
return UIImage(named: imageName)!
}
}
}
var data:[Med]=[Med]()
override func viewDidLoad() {
super.viewDidLoad()
print("OTC Loaded")
data.append(Med(name:"Nimprex P",detail:"Fever and Painkiller",imageName:"db"))
data.append(Med(name:"Cozi Plus",detail:"Cold and Fever",imageName:"db"))
data.append(Med(name:"Combiflam",detail:"Headach and Painkiller",imageName:"db"))
data.append(Med(name:"Flexon",detail:"Muscle Painkiller",imageName:"db"))
data.append(Med(name:"Avil",detail:"Antibiotic",imageName:"db"))
data.append(Med(name:"Cetirizine",detail:"Antibiotic and Allergy",imageName:"db"))
data.append(Med(name:"LIV 52",detail:"Lever Problems",imageName:"db"))
data.append(Med(name:"Perinorm",detail:"Stomach-ach and Puke",imageName:"db"))
data.append(Med(name:"Edicone Plus",detail:"Fever and Cold",imageName:"db"))
data.append(Med(name:"L-Hist Mont",detail:"Peanut Allergies",imageName:"db"))
tableView.delegate = self
tableView.dataSource = self
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return data.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("MedicineCell") as! OTCMedCell!
let medView = data[indexPath.row]
print("OTC Table Cell Loaded")
cell.medName.text = medView.name
cell.medImage.image = medView.image
cell.medDetail.text = medView.detail
return cell
}
// MARK: UITableViewDelegate Methods
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
tableView.deselectRowAtIndexPath(indexPath, animated: true)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "OTCMedPush" {
if let destination = segue.destinationViewController as? OTCMedicineDetail {
if let medIndex = tableView.indexPathForSelectedRow?.row {
destination.medicineValue = data[medIndex].name
}
}
}
}
}
Both simulator and iPhone are model 5s, running on iOS 9.2

Answer 1

I believe you need to reload the table after you added all the elements in viewDidLoad.
self.UITableView.reloadData()

Answer 2

Seems you must insert these lines in viewDidLoad:
self.tableView.registerNib(UINib(nibName: "OTCMedCell", bundle:nil), forCellReuseIdentifier: "MedicineCell")
self.tableView.reloadData()
Also, in your cellForRowAtIndexPath modify your line:
let cell = tableView.dequeueReusableCellWithIdentifier("MedicineCell") as! OTCMedCell!
with:
let cellIdentifier : String! = "MedicineCell"
var cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as? OTCMedCell!
if cell == nil {
cell = OTCMedCell(style: UITableViewCellStyle.Default, reuseIdentifier: (cellIdentifier))
}
