台风依赖注入和夫特3：的appDelegate不是AnyObject

Question

该代码可以使用台风依赖注入库（的OBJ-C）在SWIFT 2.3但在夫特3不会：

的AppDelegate：

class AppDelegate: UIResponder, UIApplicationDelegate { 

    var window: UIWindow? 
    var rootViewController: RootViewController? 

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
     // Override point for customization after application launch. 

     self.window = UIWindow(frame: UIScreen.main.bounds) 
     self.window?.rootViewController = self.rootViewController 
     self.window?.makeKeyAndVisible() 

     return true 
    } 
    ... 
} 

应用大会：

public class ApplicationAssembly: TyphoonAssembly { 

     public dynamic func config() -> AnyObject { 
      return TyphoonDefinition.withConfigName("Configuration.plist") 
     } 

     public dynamic func appDelegate() -> AnyObject { 
      return TyphoonDefinition.withClass(AppDelegate.self) { 
       (definition) in 

       definition!.injectProperty(#selector(ApplicationAssembly.rootViewController), with: self.rootViewController()) 
      } 
     } 
... 
} 

但是下面的错误是显示终端ayed在ApplicationAssembly为有望重返“AnyObject”任何斯威夫特3档： “否‘withClass’候选人产生预期的语境结果类型‘AnyObject’

也许任何人都见识到了对象 - 的不兼容性台风代码基地与Swift 3？

您可能希望从AnyObject切换返回类型Any。

的withClass函数返回在Objective-C的ID类型， see the source code：

+ (id)withClass:(Class)clazz block:(TyphoonBlockDefinitionInitializerBlock)block; 

用于夫特2被映射到AnyObject，但在夫特3它映射到Any增加的灵活性的id类型。 You can read more about this change here.
