这个崩溃是一个阻塞问题，我使用以下步骤来重现这个问题:

创建一个Cocoa Touch框架项目 添加一个swift文件和一个类Dog 为设备构建一个框架 在Swift中创建一个单视图应用程序 导入框架到应用程序项目 从ViewController中的框架实例化swift类 在设备上构建并运行应用程序

应用程序在启动时立即崩溃，这是控制台日志:

I have tried to build on iOS 7.1 and 8.0 devices, they both have the same crash. However, I can build an app and run on the simulator fine. Also, I am aware that I can change the framework to form Required to Optional in Link Binary With Libraries, but it did not completely resolve the problem, the app crashed when I create an instance of Dog. The behavior is different on the device and simulator, I suspect that we can't distribute a framework for the device using a beta version of Xcode. Can anyone shed light on this?
