Xcode8 beta6中的Apple Mach-O链接器警告,swift3.0.仍然存在于Xcode8 GM中

Question

我正在使用Xcode8 beta6,swift3.0,并获得如下编译警告:

Some object files have incompatible Objective-C category definitions. Some category 
metadata may be lost. All files containing Objective-C categories should be built using the 
same compiler.

仍然存在于Xcode8 GM中!
