I am working with Wikitude SDK and while adding some file supported in Wikitude example folder its showing me Foundation file error like below.
In file included from /Volumes/DATA/Dhanesh/Projects/experiments/AR/ARWikiDemo/ARWikiDemo/WikiSDK/Controller/Examples/Categories/PluginsAPI/CustomCamera/YUVFrameInputPlugin.cpp:11: In file included from /Volumes/DATA/Dhanesh/Projects/experiments/AR/ARWikiDemo/ARWikiDemo/WikiSDK/Controller/Examples/Categories/PluginsAPI/CustomCamera/WTDeviceCamera.h:9: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator10.3.sdk/System/Library/Frameworks/Foundation.framework/Headers/Foundation.h:8: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator10.3.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSObjCRuntime.h:492:1: error: expected unqualified-id @class NSString, Protocol;
Not getting whats wrong here but it says that
All NSString
, NSObject
, NSLog
are unqualified-id @class
I have set all related Linker flag and Header & Library search paths for that but still getting the above error.
Can anyone guide me on this whats going wrong here?

Thanks in Advance!
For the Above issue, I struggle a lot, and finally, I am concluding this with the below solution.
.cpp
file in ObjC
we required to convert that .cpp
extension to .mm
for ObjC++
compiler only. (thanks Mats for your comment it's helped me a lot.)ObjectiveC++
in the Build setting.Ref Link 1: Objective-C++ and .cpp files in Xcode
Ref Link 2: Adding C++ code to an iOS project
Hope this will help others who are facing the same issue related to it.CPP ext.
