Appending JsonFile (UrL) in array to display on application - alamofire

Question

I am trying to add my data from my Json file into the application.I want append the Authors name from the Json file into the empty array.
I have added all of the areas that needed to be added when i run the simulation i get an empty array. I need it display the Authors first name on the simulator.
Does anyone know what i need to do to my code to make it work?
My Code :
var AuthorGlobal = [String]()
class ViewController: UIViewController, UITextFieldDelegate{
#IBOutlet weak var DisplayAuthor: UITextView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
DisplayAuthor.text="\(AuthorGlobal)"
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated);
Alamofire.request(.GET, "http://178.62.83.50/newsletters.json")
.responseJSON { response in
// print(response.request) // original URL request
// print(response.response) // URL response
// print(response.data) // server data
// print(response.result) // result of response serialization
if let _ = response.result.value {
// print("JSON: \(JSON)")
}
let json = JSON(data: response.data!)
if let Author = json["NewsLetter"][0]["Author"].string {
AuthorGlobal.append(Author)
}
if let LastName = json["NewsLetter"][0]["LastName"].string {
print(LastName)
}
if let ArticleTitle = json["NewsLetter"][0]["ArticleTitle"].string {
//Now you got your value
print(ArticleTitle)
}
if let Author = json["NewsLetter"][1]["Author"].string {
//Now you got your value
print(Author)
}
if let LastName = json["NewsLetter"][1]["LastName"].string {
//Now you got your value
print(LastName)
}
if let ArticleTitle = json["NewsLetter"][1]["ArticleTitle"].string {
//Now you got your value
print ("Article Title: " + (ArticleTitle))
}
}
}

I just tried by putting your json in my file system and loading it locally. Below is my code on Swift 2 and it all worked fine. You might want to check the JSON data coming correctly in your service call. Also, try to compare it line by line with my code to see if you missed out something. Its too late for me to call it a day so bear with me to not pointing out the exact root cause in your code!
var AuthorGlobal = [String]()
class ViewController: UIViewController, UITextFieldDelegate {
#IBOutlet weak var DisplayAuthor: UITextView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
// DisplayAuthor.text="\(AuthorGlobal)"
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated);
let filePath = NSBundle.mainBundle().pathForResource("1", ofType: "json")
var fileContents : String = ""
do {
fileContents = try String(contentsOfFile: filePath!, encoding: NSUTF8StringEncoding)
} catch (_) {
}
var json : Dictionary<String,Array<Dictionary<String,String>>> = Dictionary()
do {
json = try NSJSONSerialization.JSONObjectWithData(fileContents.dataUsingEncoding(NSUTF8StringEncoding)!, options:NSJSONReadingOptions.AllowFragments) as! Dictionary<String, Array<Dictionary<String, String>>>
} catch (_) {
}
let array = json["NewsLetter"] as Array?
if let author = array?[0]["Author"] {
AuthorGlobal.append(author)
}
print(AuthorGlobal) // This prints - ["Tom"]
if let LastName = array?[0]["LastName"] {
print(LastName) // This prints - Holton
}
if let ArticleTitle = array?[0]["ArticleTitle"] {
//Now you got your value
print(ArticleTitle) // This prints - XcodeGhost: Apple suffers a major malware infection inside the iOS app store.
}
if let Author = array?[1]["Author"] {
//Now you got your value
print(Author) // This prints - Sam
}
if let LastName = array?[1]["LastName"] {
//Now you got your value
print(LastName) // This prints - Devaney
}
if let ArticleTitle = array?[1]["ArticleTitle"] {
//Now you got your value
print ("Article Title: " + (ArticleTitle)) // This prints - Article Title: Google is 2 Billion Lines of Code
}
}
