I am trying to compile my project in Xcode. But i am getting the following error.
"_OBJC_CLASS_$_InfrastructureBenchmarkingViewController", referenced from:
objc-class-ref-to-InfrastructureBenchmarkingViewController in RootViewController.o
4 more of similar type.
Can’t understand the meaning of this error?
Small Clarification: Actually the _InfrastructureBenchmarkingViewController was a module in another project. The files pertaining to that I have copied into the new application.
Sometimes it happens when the project definition file (.xcodeproj/project.pbxproj) is somehow messed-up, eg. because of XCode crash or project is taken from someone else, etc.
So try removing InfrastructureBenchmarkingViewController (Delete the file, then choose “Delete reference”, so it is not deleted physically from disc) and then again add this file to project (Add > Existing file from the project context menu).
It worked for me several times.
