Swinject 中不同 ViewController 的依赖注入不一致，post Swift 3.0 更新：为什么？

Question

我正在注册一些 Swinject singleton-with-a-small-s (.container) 服务：

defaultContainer.register( SomeService.self )
{
    _ in SomeService() 
}.inObjectScope( .container )

defaultContainer.register( AnotherService.self )
{
    responder in AnotherService(
        someService: responder.resolve( SomeService.self )!
    )
}.inObjectScope( .container )

将它们注入到一些视图控制器中：

defaultContainer.registerForStoryboard( SomeViewController.self )
{
    resolvable, viewController in
    viewController.someService = resolvable.resolve( SomeService.self )
    viewController.anotherService = resolvable.resolve( AnotherService.self )!
}

defaultContainer.registerForStoryboard( AnotherViewController.self )
{
    resolvable, viewController in
    viewController.someService = resolvable.resolve( SomeService.self )
    viewController.anotherService = resolvable.resolve( AnotherService.self )!
}

然后这些视图控制器以两种不同的方式显示，SomeViewController像这样：

DispatchQueue.main.async
{
    self.performSegue( withIdentifier: "somePageSegue", sender: nil )
}

和AnotherViewController像这样：

let anotherViewController = UIStoryboard(
    name: "Main"
    , bundle: nil
).instantiateViewController( withIdentifier: "anotherSegue" )

present( anotherViewController, animated: true, completion: nil )

SomeViewController 注入了它的服务，但不幸的是 AnotherViewController 没有。

这曾经在 Swinject 升级到 Swift 3.0 之前有效，但现在无效。请问这是为什么，需要改什么？

谢谢。

更新

不幸的是，我既不熟悉 Swinject 的底层代码库，也没有时间熟悉自己，但是深入挖掘表面下发生的事情，我发现了以下内容，希望对任何可能比我更了解它的人：

成功 VC DI:

// once into:
private func injectDependency(to viewController: UIViewController)

// then:
defaultContainer.registerForStoryboard( SomeViewController.self )

// then many times into:
public func _resolve<Service, Factory>(name: String?, option: ServiceKeyOptionType? = nil, invoker: (Factory) -> Service) -> Service?

失败 VC DI:

// repeatedly going from:
private func injectDependency(to viewController: UIViewController)

// to:
public func _resolve<Service, Factory>(name: String?, option: ServiceKeyOptionType? = nil, invoker: (Factory) -> Service) -> Service?

// and back again,
// then twice into:
public override func instantiateViewController(withIdentifier identifier: String) -> UIViewController

补充说明：

失败的 VC 是 TabBarController 中的 UIViewController，两者都已在标准 XCode 情节提要中布置。

为了调用 registerForStoryboard，您需要从 SwinjectStoryboard 实例化给定的控制器，而不仅仅是 UIStoryboard:

let anotherViewController = SwinjectStoryboard.create(name: "Main", bundle: nil)
    .instantiateViewController(withIdentifier: "anotherSegue")

present(anotherViewController, animated: true, completion: nil)

事实证明这是一个错误，详细信息在这里：https://github.com/Swinject/Swinject/issues/177。目前正在修复。一旦我知道更多，我会报告。

这显然是固定的。
