iPhone App : How to get default value from root.plist?

Question

I am working on an iPhone app

I read a key from root.plist like this :

NSString *Key1Var = [[NSUserDefaults standardUserDefaults] stringForKey:@\"Key

I've translated Mike Weller's solution into Swift 2.0/iOS 9 and made it work for my App:

func registerDefaultsFromSettingsBundle() {
    guard let settingsBundle = NSBundle.mainBundle().URLForResource("Settings", withExtension:"bundle") else {
        NSLog("Could not find Settings.bundle")
        return;
    }

    guard let settings = NSDictionary(contentsOfURL: settingsBundle.URLByAppendingPathComponent("Root.plist")) else {
        NSLog("Could not find Root.plist in settings bundle")
        return
    }

    guard let preferences = settings.objectForKey("PreferenceSpecifiers") as? [[String: AnyObject]] else {
        NSLog("Root.plist has invalid format")
        return
    }

    var defaultsToRegister = [String: AnyObject]()
    for var p in preferences {
        if let k = p["Key"] as? String, v = p["DefaultValue"] {
            NSLog("%@", "registering \(v) for key \(k)")
            defaultsToRegister[k] = v
        }
    }

    NSUserDefaults.standardUserDefaults().registerDefaults(defaultsToRegister)
}
