我一直在尝试将Obj-C库移植到Swift，但是遇到了一个问题，当Swift代码在项目中时，链接器无法构建静态库。

作为最小的复制者，请进入XCode6并创建一个新的iOS静态库。它会为您提供一个带有空白.h和.m文件的项目。这样可以编译良好。然后，将新的.swift文件添加到项目中（无论是否创建标题桥）。这也
应该 编译良好，但是在链接期间失败：

如果我瞄准模拟器或设备，则会发生这种情况。看起来项目中包含Swift文件可能导致它使用通常为可执行程序保留的链接器选项，即使目标是静态库也是如此？我对构建选项了解不足，无法确定这是Beta中的错误还是我应该配置的某些选项。在这样一个琐碎的例子上，该构建是否会合法失败似乎令人怀疑。有什么想法吗？
