无法从Xcode 6.1中的情节提要板连接自定义协议委托 [英] Can not connect custom protocol delegate from storyboard in Xcode 6.1

问题描述

我刚刚将Mac升级到10.10，将Xcode升级到6.1，

I just upgraded my mac to 10.10 and Xcode to 6.1,

发现了一个关于情节提要的奇怪事情，

found a strange thing which about storyboard,

我的案例正在使用一个快速项目，无法再从情节提要中连接自定义协议委托.

my case is using a swift project, can not connect custom protocol delegate from storyboard anymore.

旧版本的Xcode附带的旧连接很好，但是我无法再连接任何新的委托.

the old connected which comes with old version of Xcode is fine, but I can not connect any new delegate anymore.

即使我删除了旧的连接，也无法重新连接旧的连接.

even I can not reconnect the old one once I removed the connected.

有人发生这种情况吗?

Interface Builder

Interface Builder不支持连接到Swift中的插座 当插座的类型为协议时，文件.声明出口的类型 作为AnyObject或NSObject，使用 Interface Builder，然后将插座的类型改回协议. (17023935)

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)

太烂了...
