IOS Xcode 8 Dsymulti警告

嗨，我只是更新我的项目到Xcode 8，但不知道为什么我的Xcode控制台洪水与Dsymulti警告消息。

while processing /Volumes/Data/OneDrive/Singpost/Esam/Vic/Version1/SAM/eSAM/SAMKiosk/Classes/Libs/NETS/libNETS.a(NETS.o): warning: /Users/Chetas/Library/Developer/Xcode/DerivedData/ModuleCache/9CPWN0R8YQPE/Foundation-A3SOD99KJ0S9.pcm: No such file or directory note: Linking a static library that was built with -gmodules, but the module cache was not found. Redistributable static libraries should never be built with module debugging enabled. The debug experience will be degraded due to incomplete debug information. while processing /Volumes/Data/OneDrive/Singpost/Esam/Vic/Version1/SAM/eSAM/SAMKiosk/Classes/Libs/NETS/libNETS.a(NETS.o): warning: /Users/Chetas/Library/Developer/Xcode/DerivedData/ModuleCache/9CPWN0R8YQPE/ObjectiveC-2CD0WTQVXITO7.pcm: No such file or directory while processing /Volumes/Data/OneDrive/Singpost/Esam/Vic/Version1/SAM/eSAM/SAMKiosk/Classes/Libs/NETS/libNETS.a(NETS.o): warning: /Users/Chetas/Library/Developer/Xcode/DerivedData/ModuleCache/9CPWN0R8YQPE/CoreFoundation-10I2D2XL7L7X9.pcm: No such file or directory 

我的项目仍然可以成功build立。 任何人都知道我们该如何处理这些警告？ 谢谢！
