I'm new to the world of Swift and I have no idea what I'm doing! I'm developing an app for work to pull a list of emails from a server as well as attachments if the email has one. I'm running into two problems. First problem is that I can't seem to convert from NS Dictionary to NSArray and I've spent days searching StackOverflow for a solution that worked to no avail, so maybe it's from how I wrote the code? The next problem is after that I have to pull the URLs of the emails based on the ID from the NSDictionary. The ID is also the last part of each email's URL but I have no idea to even begin to approach that concept.
Sorry to sound needy, but I'm not a software developer by trade, or even in training (I'm a senior in college for Networking/Systems) so I'm having issues wrapping my head around this programming logic that I don't understand. Here's the code I've managed to put together so far (Note: It breaks at line 72 self.Table = JsonWithDatos as! NSArray:
import Foundation
import UIKit
class TableViewControllerNews: UITableViewController {
@IBOutlet weak var searchBar: UISearchBar!
@IBOutlet weak var Submit: UIView!
var Table:NSArray = []
override func viewDidLoad() {
super.viewDidLoad()
CallWebService()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func CallWebService()
{
let UrlApi = "********"
let Url = NSURL(string: UrlApi)
let Session = NSURLSession.sharedSession()
let Work = Session.dataTaskWithURL(Url!, completionHandler: { dataTask, response, error -> Void in
if (error != nil)
{
print(error)
}
let datos:NSData = NSData(data: dataTask!)
print(datos)
print(response)
self.ParseoDataToJson(datos)
})
Work.resume()
}
func ParseoDataToJson(datos:NSData)
{
do {
let JsonWithDatos:AnyObject! = try NSJSONSerialization.JSONObjectWithData(datos, options: NSJSONReadingOptions.MutableContainers)
print(JsonWithDatos)
struct AnnouncementList {
var ID: NSArray?
var Subject: NSArray?
init(announcementObject: AnyObject) {
// announcements = (announcementObject["Announcements"] as NSArray)
if let announcements = announcementObject["Announcements"] as? NSArray {
ID = (announcements.valueForKey("ID") as! NSArray)
Subject = (announcements.valueForKey("Subject") as! NSArray)
}
}
}
self.Table = JsonWithDatos as! NSArray
print(self.Table)
print(self.Table.count)
self.tableView.reloadData()
}
catch {
print("Error")
}
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.Table.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
let item = self.Table[indexPath.row] as! [String : String]
cell.textLabel!.text = item["Subject"]
return cell
}
override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
return false
}
}
URLs and Email subjects removed for security.

If I am not mistaken, you simply do not get an array back (in JSON form), but a dictionary (a hash table). Try
self.Table = JsonWithDatos["GetPreShiftsResult"] as! NSArray
You don't even need the explicit cast I think (assuming self.Table is already an NSArray).
