This happened to me when I had simultaneously installed both Xcode 7 and 7.3 and after automatic update I was left with 8.0 only.

当我同时安装 Xcode 7 和 7.3 并且自动更新后我只剩下 8.0 时，这发生在我身上。

One indication that something got messed up was output of xcodebuild -sdk -versionin terminal:

出现问题的一个迹象是xcodebuild -sdk -version终端中的输出：

DVTSDK: Warning: SDK path collision for path '<DVTFilePath:0x7fd810db4c50:'/Applications/Xcode.app/Contents/Developer/Platforms/WatchOS.platform/Developer/SDKs/WatchOS3.0.sdk'>': SDK with name 'watchos3.0' being superceded by SDK with 'watchos3.0'.

Solution:

解决方案：

1. Quit Xcode
2. go to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
3. remove the iPhoneOS9.3.sdkfolder from that directory. Be sure to make an external copy if you still need it so you can put it back later.
4. restart Xcode, clean, and build
5. ???

更新：

According to @tsafrir comment, delete also 'iPhoneOS9.3.sdk' for simulator folder: /Applications/Xcode.app/Contents/Developer/Platforms/iPhon??eSimulator.platform/??Developer/SDKs

根据@tsafir 评论，还删除模拟器文件夹的“iPhoneOS9.3.sdk”： /Applications/Xcode.app/Contents/Developer/Platforms/iPhon??eSimulator.platform/??Developer/SDKs

The iPhoneOS9.3.sdkfor the simulator is at Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs.

在iPhoneOS9.3.sdk为模拟器是Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs。

Not the best solution, but selecting - "Use Legacy Compiler Version": Yes, removed that warning for me.

不是最好的解决方案，而是选择 - “使用旧版编译器版本”：是的，为我删除了该警告。
