After I updated my Xcode toXcode 8.

I found out that if I import vendor framework header files in .pch file. there will be a error. 'xxx' .h file not Found

Such as:
I want to import a framework named Umeng's header file. So I write the codes below to my XXX-prefix.pch 

#import <UMMobClick/MobClick.h>

But Error UMMobClick/MobClick.h file not found appeared.

Any constriction of Xcode that prohibit importing vendor framework header files in .pch file?

I had a similar problem with a legacy Xcode project that used a .pch file -- the file was being ignored.

The fix was in build settings, where the original path to this file assumed it began at the project root:

SharkAlert/SharkAlert-Prefix.pch

Xcode 8 apparently requires an explicit reference to the starting point

$(SRCROOT)/SharkAlert/SharkAlert-Prefix.pch

Now the project builds as expected.

If this file you are used to bridge OC and Swift，now you should creat a new .header file and Move All Header file Name inside file

I had a similar issue. Changing #import <Framework/Framework.h> to @import Framework; fixed it for me.
