Swift NSUserDefaults not saving Dictionary?

Question

I have the following test code:

  func testSaveDictionary() {
    let userDefaults = NSUserDefaults.standardUserDefaults()
    var jo = [
      \"a\" : \"1.0

I faced with this problem yesterday and filed a radar: Cannot store Dictionary in NSUserDefaults in iOS8. This issue is related only to iOS 8. Also I described a workaround for this case: Workaround for saving dictionary in NSUserDefaults. Works like a charm.

/// Save
NSUserDefaults.standardUserDefaults().setObject(NSKeyedArchiver.archivedDataWithRootObject(object), forKey: key)

/// Read
var data = NSUserDefaults.standardUserDefaults().objectForKey(key) as NSData
var object = NSKeyedUnarchiver.unarchiveObjectWithData(data) as [String: String]
