Swift 3 - 未解決の識別子「静的」の使用

Question

私はiOSアプリでクリーンアーキテクチャを実装するために、this exampleに従っています。

class CreateOrderConfigurator 
{ 
    private static var __once:() = { 
     //ERROR - use of unresolved identifier 'Static' 
     Static.instance = CreateOrderConfigurator() 
    }() 


    // MARK: Object lifecycle 

    class var sharedInstance: CreateOrderConfigurator 
    { 
    struct Static { 
     static var instance: CreateOrderConfigurator? 
     static var token: Int = 0 
    } 

    _ = CreateOrderConfigurator.__once 

    return Static.instance! 
    } 

    // MARK: Configuration 

    func configure(_ viewController: CreateOrderViewController) 
    { 
    let router = CreateOrderRouter() 
    router.viewController = viewController 

    let presenter = CreateOrderPresenter() 
    presenter.output = viewController 

    let interactor = CreateOrderInteractor() 
    interactor.output = presenter 

    viewController.output = interactor 
    viewController.router = router 
    } 
} 

エラーはuse of unresolved identifier 'Static'と表示されます。これをどうすれば解決できますか？

PS：私はシングルトンが

static let sharedInstance = CreateOrderConfigurator() 

と

private static var __once:() = { 
     //ERROR - use of unresolved identifier 'Static' 
     Static.instance = CreateOrderConfigurator() 
    }() 


    // MARK: Object lifecycle 

    class var sharedInstance: CreateOrderConfigurator 
    { 
    struct Static { 
     static var instance: CreateOrderConfigurator? 
     static var token: Int = 0 
    } 

    _ = CreateOrderConfigurator.__once 

    return Static.instance! 
    } 

を交換しスウィフト
