swift：无法与Interface Builder进行通信
我刚刚在xcode 6 beta中打开了现有的项目。 但它与以下错误信息崩溃。

这解决了Interface Builder问题。
cd /Applications/Xcode.app cd Contents/Developer/Platforms/iPhoneSimulator.platform cd Developer/SDKs/iPhoneSimulator.sdk/usr/lib sudo mv dyld_sim dyld_sim.orig
根据@ThePaddedCell，我做了以下步骤，它终于为我工作
1） Move xcode6-beta Move到应用程序文件夹中
2） Restart Mac并从应用程序文件夹中打开xcode6-beta。
但我不知道为什么..如果有人知道这个原因，欢迎更新我的答案。
移动你的Xcode到应用程序，然后检查它是否还没有解决问题，然后重新启动你的Mac，并从应用程序打开Xcode。
