使用 swift 更新到 Xcode 6 beta 4 后获取 dyld_fatal_error [英] Getting dyld_fatal_error after updating to Xcode 6 beta 4 using swift

问题描述

我最近刚刚下载了 Xcode 6 beta 4，我的 swift 项目编译没有错误，但在它进入我的代码之前，我在调用堆栈的 start 上方得到一个 dyld_fatal_error.

I just recently downloaded Xcode 6 beta 4, and my swift project compiles with no errors but before it gets to my code I get a dyld_fatal_error just above start in the call stack.

以及一些带有 nop 指令的汇编代码中的断点

and a breakpoint in some assembly code with a nop instruction

我得到的控制台错误是

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

只是让您知道该项目仍然可以编译，并且可以在 Xcode 6 beta 3 中正常运行.

Just so you know the project still compiles, and runs fine with Xcode 6 beta 3.

推荐答案

像这样的最奇怪的问题都可以通过 Clean & 解决.构建(或者可能重新启动 Xcode).您也可以考虑从 ~/Library/Developer/Xcode/DerivedData 中删除相关文件夹.

Most extremely weird problems like this can be solved with a Clean & Build (or perhaps relaunch Xcode). You might also consider deleting the relevant folders from ~/Library/Developer/Xcode/DerivedData.
