Swift - read plist file to an array?

Question

I have created a mini translation from English words to Spanish words. I would like to use the englishArray.plist instead of my englishArray = [\"the cat\"] How can I create thi

Answer 1

This will read a resource in your bundle with the name "englishArray.plist" and store it in the immutable variable english. It will be an Optional that you should test before using.

It uses a closure to read the file and return the array, this lets you use a immutable value rather than a mutable variable that can be changed. It's a good idea to use immutables wherever you can - they promote stability.

import Foundation

let english:[String]? = {
  guard let URL = NSBundle
    .mainBundle()
    .URLForResource("englishArray", withExtension: "plist") else {
      return nil
  }
  return NSArray(contentsOfURL: URL) as? [String]
}()
