objective-c - 如何在 Objective-C 中使用带有扩展的 Swift 协议？

Question

我正在尝试在 Objective-C 类中使用 Swift，但语法有问题，或者即使有可能。下面是我正在尝试的。

迅速：

@objc protocol MyProtocol {

    var someManager: MyManager? { get set }
    var someState: MyState { get set }

}

extension MyProtocol {

    func didLoad(delegate: MyProtocol) {

    }

}

class ViewController: MyProtocol {

  var someManager: MyManager?
  var someState: MyState = .Unknown

  override func viewDidLoad() {
    super.viewDidLoad()
    didLoad(self as MyProtocol)
  }

}

目标-C：

@interface ViewController : UIViewController<MyProtocol>

@end

@interface ViewController()

  @property (nonatomic, assign) MyManager *someManager; //?? Error: Illegal redeclaration of property in class extension ‘ViewController’ (attribute must be ‘readwrite’, while its primary must be ‘readonly’)
  @property (nonatomic, assign) MyState someState; //??

@end

@implementation HomeViewController

-(void)viewDidLoad {
  [super viewDidLoad];
  [self didLoad:(self as MyProtocol)] //??
}

如何让 Objective-C ViewController 工作？我有一个例子说明它应该如何在 Swift 中工作。谢谢你的帮助。
