UItableView not populating while offline? swift 3 - ios

Question

The problem is really, that while offline the UItableview is not populating. Basically while online it will read from a php coded website in json and parse its data to NSUserdefaults and It will display data using the defaults set. This works very well when online.
I tested it like this. first I run the code while online( wifi connected ) to first populate the defaults, then exit the tableview, turn wifi off, and then go back in. Nothing shows. I put a breakpoint/print text where the code should had run, but it breakpoint never got excuted, the print text never got printed.
is there a reason why the code isnt running when offline? am i missing a setting i should add?
var messagesArray:[String] = [String]()
var dateArray:[String] = [String]()
class Singleton {
static let sharedInstance: UserDefaults = {
let instance = UserDefaults.standard
// setup code
return instance
}()
}
//let defaults = UserDefaults.standard
let defaults = Singleton.sharedInstance
override func viewDidLoad() {
super.viewDidLoad()
//removeDefaults()
if (isInternetAvailable() == true)
{
self.retrieveMessages("")
//storeLocal()
}
else {
// TODO data is available but not displayed ??
for (key, value) in defaults.dictionaryRepresentation() {
print("\(key) = \(value) \n")
}
}
//display current notification
//nRead()
self.notificationTable.dataSource = self
self.notificationTable.delegate = self
// Do any additional setup after loading the view.
}
func tableView(_ tableView:UITableView, numberOfRowsInSection section: Int) -> Int{
return messagesArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// this code does not run when offline
//test
let nCell = tableView.dequeueReusableCell(withIdentifier: "nCell") as UITableViewCell!
//let myLabelTitle = nCell?.viewWithTag(1) as! UILabel
let myLabelDate = nCell?.viewWithTag(2) as! UILabel
let myLabelDescription = nCell?.viewWithTag(3) as! UILabel
//messagesArray ["nContent":["Test1", "Test2"]]
myLabelDescription.text = defaults.string(forKey: "nDescription\(indexPath.row + 1)")
myLabelDate.text = defaults.string(forKey: "nDate\(indexPath.row + 1)")
//print(defaults.string(forKey:"nDate1"))
print("this code runs even while offline")
let readValue = defaults.string(forKey: "nRead\(indexPath.row + 1)")
if (readValue == "1" )
{
myLabelDate.textColor = UIColor.black
}
else
{
myLabelDate.textColor = UIColor.red
}
return nCell!
}

func tableView(_ tableView:UITableView, numberOfRowsInSection section: Int) -> Int{
return messagesArray.count
}
messagesArray.count prints 0, thus the code isn't running. fixed my own issue
