Product:macOS + SDK Product Version:Xcode 9b5 (9M202q)
Classification:Serious Bug Reproducible:Always
 
Area:
Xcode

Summary:
It’s impossible to compile any Objective-C code that uses AVFoundation.framework by #importing <AVFoundation/AVFoundation.h>.

<AVFoundation/AVFoundation.h> #imports <AVFoundation/AVRouteDetector.h>, but this file is not present in the SDK. It was introduced in Xcode 9 beta 2 (9M137d), and present in betas 3 (9M174d) and 4 (9M189t), but is gone in beta 5 (9M202q).

Steps to Reproduce:
% cat t.m
#import <AVFoundation/AVFoundation.h>
% clang -c t.m -o t.o
In file included from t.m:1:
/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/System/Library/Frameworks/AVFoundation.framework/Headers/AVFoundation.h:88:9: fatal error: 
      'AVFoundation/AVRouteDetector.h' file not found
#import <AVFoundation/AVRouteDetector.h>
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

Expected Results:
% clang -c t.m -o t.o

should remain silent and produce the object file t.o.

Observed Results:
% clang -c t.m -o t.o
In file included from t.m:1:
/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/System/Library/Frameworks/AVFoundation.framework/Headers/AVFoundation.h:88:9: fatal error: 
      'AVFoundation/AVRouteDetector.h' file not found
#import <AVFoundation/AVRouteDetector.h>
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
