Swift: read multiple words from Localizable string

Question

I've created this mini translation of words from English to Spanish. The words read from a Localizable.strings and retrieves the words "cat" = "gato" using NSLocalizedString. At the moment it only read one word from the string, I would like yo know if there's any way to retrieve multiple words from Localizable.string, for example, "the" + "cat" = "el gato"

var myEnglishArray = [String]()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    self.translateTextField.delegate = self
    picker.delegate = self
    picker.dataSource = self


    //var myEnglishArray = [String]()
    if let URL = NSBundle.mainBundle().URLForResource("englishArray", withExtension: "plist") {
        if let englishFromPlist = NSArray(contentsOfURL: URL) as? [String] {
            for myEnglish in englishFromPlist {
                myEnglishArray.append(myEnglish)
            }
        }
    }

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


@IBAction func translateButtonTapped(sender: UIButton) {

    let emptyString = self.translateTextField.text

    if (emptyString!.isEmpty) {

        print("please enter a word")

    }

    for transIndex in myEnglishArray.indices {
        if myEnglishArray[transIndex] == emptyString!.lowercaseString {

            //englishArray

            //translateLabel.text = "\(spanishArray[transIndex])"
            translateLabel.text = NSLocalizedString(emptyString!.lowercaseString, comment:"")


            print(emptyString)
            return

        }
    }
}

Answer 1

I think that you should use Localization for iOS - not files or arrays or anything like that.

You will need to create several localizable.strings files and use that one as a key, for instance NSLocalizedString("yourKeyForWordYouWantToTranslate", comment: "").

So, if you want this code to work, again, you have to create localizable strings and setup your project to have several languages supported. Here is a great tutorial on this case (applies to swift as well):
