使用 swift 更新到 Xcode 6 beta 4 后获取 dyld_fatal_error

我最近刚刚下载了Xcode 6 beta 4，我的swift项目编译时没有出现错误，但在我的代码中，我在调用堆栈的start上方出现了一个dyld_fatal_错误.

以及一些汇编代码中带有nop指令的断点

我得到的控制台错误是

dyld: lazy symbol binding failed: Symbol not found: __TFSsa6C_ARGVGVSs13UnsafePointerGS_VSs4Int8__

正如您所知，该项目仍然可以编译，并且在Xcode 6 beta 3中运行良好.
