swift – 无法在Xcode 6.1中连接故事板中的自定义协议委托

我刚刚将我的mac升级到10.10,将 Xcode升级到6.1,

发现一个关于故事板的奇怪的事情,

我的情况是使用swift项目,无法再从故事板连接自定义协议委托.

老版Xcode附带的旧连接很好,但我再也无法连接任何新的代理了.

一旦我移除了连接,我甚至无法重新连接旧的.

有没有人出现这种情况？

View Class

@objc public protocol VideoViewResizeDelegate {

    func shouldVideoViewResetLayout(videoView: GvVideoView) -> Bool;

}

@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.

这很糟糕……
