SwiftyJSON Problems Swift 2 - json

Question

I have a API URL that return JSON data, which you can find here https://itunes.apple.com/us/rss/topmovies/limit=25/json
I want to return all of the movie titles in this JSON data.
I am using the SwiftyJSON Framework to parse the JSON data from the URL. I am using a NSURLSession.dataTask to begin the Parse from the URL.
The problem is that the JSON data I want to return is not returning anything.
Here is some code -
JSON Data URL -
let url = "https://itunes.apple.com/us/rss/topmovies/limit=25/json"
Retrieving JSON Data
func getTheJSONData() throws {
let theURL = NSURL(string: url)
let request = NSURLRequest(URL: theURL!)
//let JSONError : NSError?
let session = NSURLSession(configuration: NSURLSessionConfiguration.defaultSessionConfiguration())
let task = session.dataTaskWithRequest(request) { (data, response, error) -> Void in
do {
if error == nil{
let swiftyJSON = JSON(data: data!, options: NSJSONReadingOptions.MutableContainers, error: nil)
let Name = swiftyJSON["feed"]["entry"][0]["im:name"]["label"].stringValue
//prints nil..
print(Name)
}
} catch {
// report error
print(error)
}
}
task.resume()
}

Your code does exactly what it's supposed to: it prints the title of a movie.
With this:
let Name = swiftyJSON["feed"]["entry"][0]["im:name"]["label"].stringValue
print(Name)
you get the title of one movie because you're getting the first element of the array with [0].
Since you want to get all movies titles, instead of working with the first element, work with all elements. Example:
let swiftyJSON = JSON(data: data!, options: NSJSONReadingOptions.MutableContainers, error: nil)
let movies = swiftyJSON["feed"]["entry"].arrayValue
let titles = movies.map { $0["im:name"]["label"].stringValue }
print(titles)
print(titles) gives an array of titles:
["Jurassic World", "Avengers: Age of Ultron", "Spy", "Entourage", "Pixels", "Froning", "Pitch Perfect 2", "Cartel Land", "Aladdin", "Furious 7 (Extended Edition)", "Magic Mike XXL", "\'71", "The Age of Adaline", "Cast Away", "Cinderella (2015)", "San Andreas", "Mad Max: Fury Road", "Hotel Transylvania", "Paddington", "Mission: Impossible - Ghost Protocol", "Aloha", "Dope", "Man on Wire", "Me and Earl and the Dying Girl", "The Overnight"]
By the way, as the compiler says with the warning, there's no need to use do catch for JSON() because it doesn't throw.
