swift - 无法从 Xcode 6.1 中的 Storyboard连接自定义协议(protocol)委托(delegate)

Question

我刚刚将我的 mac 升级到 10.10，将 Xcode 升级到 6.1，

发现一个关于 Storyboard的奇怪的东西，

我的案例使用的是一个 swift 项目，无法再从 Storyboard连接自定义协议(protocol)委托(delegate)。

老版本 Xcode 自带的旧连接没问题，但我不能再连接任何新的委托(delegate)。

即使我删除连接后也无法重新连接旧的。

有人遇到这种情况吗？？

}

@IBOutlet var resizeDelegate: VideoViewResizeDelegate?;

ViewController Class

@IBDesignable public class ViewController: UIViewController, VideoViewResizeDelegate {

...

}

Interface Builder

Interface Builder does not support connecting to an outlet in a Swift file when the outlet’s type is a protocol. Declare the outlet's type as AnyObject or NSObject, connect objects to the outlet using Interface Builder, then change the outlet's type back to the protocol. (17023935)

这很糟糕......
