How can I store an array in a separate file?

Question

I'am planing to use a couple of large arrays in my project and like to store the arrays in a separate file. is this possible? here is my main viewcontroller example with the array "gruppe" I like to have in a separate file:

import UIKit
class ViewController: UIViewController {
var gruppe = ["new york", "sydney", "paris"]
@IBAction func knopf(sender: UIButton) {
println(gruppe[0])
}
}

You could try something like:

// File 1
import UIKit
class ViewController: UIViewController {

    @IBAction func knopf(sender: UIButton) {
        println(DataClass.gruppe()[0])
    }
}

// File 2
class DataClass {
    class func gruppe() -> [String] {
        return ["new york", "sydney", "paris"]
    }
}

You can bridge a Swift array to a NSArray.

doing something like:

let cocoaArray : NSArray = gruppe
cocoaArray.writeToFile("pathToYourFile", atomically:true)

Sorry, not an external File, only in a second SWIFT file. – Yvana Nov 23 '14 at 12:40
your question is confusing then. Do you want to make a *duplicate* array within Swift? – Michael Dautermann Nov 23 '14 at 12:45
I'm assuming he just wants to decouple the data from the logic. Perfectly sensible. – Grimxn Nov 23 '14 at 12:49
