Remote Data won't show on tableView - swift

Question

I'm clueless as to what is wrong. My console doesn't give me any errors, my code seems fine but nothing is showing up. Could someone check my code, see why it doesn't want to work? My tableView is connected with its delegates and source. Not sure what is the problem.
Here is my code:
private let cellIdentifier = "cell"
private let apiURL = "api link"
class TableView: UITableViewController {
//TableView Outlet
#IBOutlet weak var LegTableView: UITableView!
//API Array
var legislatorArray = [congressClass]()
func getLegislators (fromSession session: NSURLSession) {
//Calling url
if let jsonData = NSURL(string: apiURL) {
// Requesting url
let task = session.dataTaskWithURL(jsonData) {(data, response, error) -> Void in
//Check for errors
if let error = error {print(error)
} else {
if let http = response as? NSHTTPURLResponse {
if http.statusCode == 200 {
//Getting data
if let data = data {
do {
let legislatorData = try NSJSONSerialization.JSONObjectWithData(data, options: .MutableContainers)
//Get API data
if let getData = legislatorData as? [NSObject:AnyObject],
findObject = getData["results"] as? [AnyObject]{
//Return data
for cellFound in findObject{
if let nextCell = cellFound["results"] as? [NSObject:AnyObject],
name = nextCell["first_name"] as? String,
lastName = nextCell["last_name"] as? String,
title = nextCell["title"] as? String,
partyRep = nextCell["party"] as? String,
position = nextCell ["position"] as? String,
id = nextCell ["bioguide_id"] as? String
{
//Add data to array
let addData = congressClass(name: name, lastName: lastName, title: title, party: partyRep, position: position, bioID: id)
self.legislatorArray.append(addData)
}
}//end cellFound
//Adding data to table
dispatch_async(dispatch_get_main_queue()) { () -> Void in
self.tableView.reloadData()
}
}
}
//end do
catch {print(error)}
}//end data
}//end statusCode
}//end http
}//else
}//end task
//Run code
task.resume()
}//end jsonData
}
override func viewDidLoad() {
super.viewDidLoad()
let sessionConfig = NSURLSessionConfiguration.defaultSessionConfiguration()
let urlSession = NSURLSession(configuration: sessionConfig)
getLegislators(fromSession: urlSession)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
//TableView Rows
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return legislatorArray.count
//return 5
}
//Cell Configuration
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! CellTableView
cell.lesName?.text = legislatorArray[indexPath.row].name + " " + legislatorArray[indexPath.row].lastName
cell.lesTitle?.text = legislatorArray[indexPath.row].title
cell.lesParty?.text = legislatorArray[indexPath.row].party
//These tests worked fine.. the tableView is working. But the data doesn't seem to pass.
//cell.lesName.text = "Name" + " " + "lastName"
//cell.lesTitle.text = "Title goes here"
//cell.lesParty.text = "D"
return cell
}
}

You're not reloading the tableView
The problem is in this piece of code
//-----------------------------
//New empty array for api data
var indexPath:[NSIndexPath] = []
//Adding data to new array
for i in 0..<self.legislatorArray.count{
let secondIndexPath = NSIndexPath(forRow: i, inSection: 0)
indexPath.append(secondIndexPath)
}
//Adding data to table
dispatch_async(dispatch_get_main_queue()) { () -> Void in
self.tableView.insertRowsAtIndexPaths(indexPath, withRowAnimation: .Left)
}
You don't need any of that. You can just reload the tableView as follows:
//Adding data to table
dispatch_async(dispatch_get_main_queue()) { () -> Void in
//You only need to reload it and that should do the trick
self.tableView.reloadData()
}
I know you said your tableView is connected to the delegate and dataSource but it's not showing in your code.
You conformed the ViewController to the correct protocols but you need something like this in your viewDidLoad.
self.tableView.deletage = self
self.tableView.dataSource = self
//I don't know if this was a typo but in your cellForRowAtIndexPath you are using CellTableView
let nibName = UINib(nibName: "CellTableView", bundle:nil)
self.tableView.registerNib(nibName, forCellReuseIdentifier: cellIdentifier)
I created an example of a better design for your implementation
This is for the WebService and your Custom Class
https://github.com/phantomon/Stackoverflow/blob/master/SO1/MyTableView/MyTableView/Models/WebServiceManager.swift
This is for the ViewController with your tableView
https://github.com/phantomon/Stackoverflow/blob/master/SO1/MyTableView/MyTableView/ViewController.swift
You just need to modify the UITableViewCell with your custom one.
And of course review your custom class data.
