For those who are curious, the .tbd files are new "text-based stub libraries", that provide a much more compact version of the stub libraries for use in the SDK, and help to significantly reduce its download size.
简单说.tbd 又是和苹果压缩 iOS 系统和应用体积的政策的产物。
.tbd 出错了
如果你在使用.tbd 时出现类似这样的的错误:
warning: skipping file ‘/Users/me/xcode7/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.0.sdk/usr/lib/libz.tbd’ (unexpected file type ‘text’ in Frameworks & Libraries build phase)”
请参考下面的解决办法:
To work around this issue for now, please:
Delete all references to .tbd files from either your linked libraries phase, or from the copied bundle resources phase (where they sometimes will be added).
Add the library you want to link manually to the "Other Linker Flags" build settings, by adding the argument:
-l<library_name>
for each library you want to link (for example, add "-lsqlite3" (without quotes)).
