    let pathStr = Bundle.main.bundlePath
    let settingsBundlePath = (pathStr as NSString).appendingPathComponent("Settings.bundle")
    let finalPath = (settingsBundlePath as NSString).appendingPathComponent("Root.plist")
    let settingsDict = NSDictionary(contentsOfFile: finalPath)
    guard let prefSpecifierArray = settingsDict?.object(forKey: "PreferenceSpecifiers") as? [[String: Any]] else {
        return
    }

    var defaults = [String: Any]()

    for prefItem in prefSpecifierArray {
        guard let key = prefItem["Key"] as? String else {
            continue
        }
        defaults[key] = prefItem["DefaultValue"]
    }
    userDefaults.register(defaults: defaults)
}
