静态链接Swift,XCode6-Beta

Question

我一直在尝试将一个Obj-C库移植到Swift,我遇到了一个问题,当Swift代码在项目中时,链接器无法构建静态库.

作为最小的再现器,进入XCode6并创建一个新的iOS静态库.它会给你一个带有空白.h和.m文件的项目.这将编译好.然后,将新的.swift文件添加到项目中(创建或不创建标题桥).这也应该编译好,但在链接期间失败:

Libtool /Users/alexkarantza/Library/Developer/Xcode/DerivedData/Test-alenfoymgkewlghfjjvizjjuvign/Build/Products/Debug-iphonesimulator/libTest.a normal i386

如果我的目标是模拟器或设备,就会发生这种情况.看起来可能在项目中使用Swift文件导致它使用通常为可执行文件保留的链接器选项,即使目标是静态库？我不太了解构建选项,以了解这是否是测试版中的错误,或者我应该配置的一些选项.在这样一个微不足道的例子中,构建将合法地失败似乎是值得怀疑的.有什么想法吗？

为了在评论中进行一些讨论后回答我自己的问题,根本不可能构建包含Swift代码的静态库.我在Beta 4中写这篇文章,发行说明仍然在"Xcode 6 beta 4中的已知问题"中说:

Xcode不支持构建包含Swift代码的静态库.(17181019)
