DiskVar

Provide a convenience method to access NSUserDefaults

Usage:

 class ViewController: UIViewController {

    private var history = DiskVar<[String]>(key: "ViewController.history", defaultValue: ["cat"])

    override func viewDidLoad() {
        super.viewDidLoad()

        // get
        print(history.value)        // ["cat"]

        // set
        history.value.append("dog") // ["cat", "dog"]

    }

 }

ViewController’s Property “history” is a Array of String which has a defaultValue of [“cat”]. “ViewController.history” is the key used in NSUserDefaults which should be unique in the project. And the history’s value will not be lost even if the app is closed.
