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

A Swift 3 version based on Mike Weller's original solution if anyone needs it:

static func registerDefaultsFromSettingsBundle() {

    guard let settingsBundle = Bundle.main.url(forResource: "Settings", withExtension: "bundle") else {
        print("Could not find Settings.bundle")
        return
    }
    guard let settings = NSDictionary(contentsOf: settingsBundle.appendingPathComponent("Root.plist")) else {
        print("Couldn't find Root.plist in settings bundle")
        return
    }

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

    var defaultsToRegister = [String: AnyObject]()
    for var p in preferences {
        if let k = p["Key"] as? String, let v = p["DefaultValue"] {
            print("Registering " + v.debugDescription + " for key " + k)
            defaultsToRegister[k] = v as AnyObject
        }
    }

    UserDefaults.standard.register(defaults: defaultsToRegister)
}
