我在我的新的Swift 2.0项目中使用一些来自google的外部代码，在早期版本中需要“libz.dylib”。更新到新的XCode /新的SDK后。
XCode现在无法导入libz.dylib并引发一些错误
Undefined symbols for architecture i386:

当在“构建阶段”设置中查找可用的包时，我可以找到“libz.tbd”，这似乎是libz.dylib的替代品。当导入这个库时，链接器错误保持不变，但我得到这个额外的警告：
warning: skipping file ‘/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator9.0.sdk/usr/lib/libz.tbd’ (unexpected file type ‘text’ in Frameworks & Libraries build phase)
任何想法该怎么办？
