When trying to run my project I get this error and I don´t know what it means :
_OBJC_CLASS_$_MyWindowController”, referenced from:
objc-class-ref in AppDelegate.
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
What does it mean and how can I get rid of it?
Any ideas?
Select the application target, go to the Build Phases tab and make sure MyWindowController.m is in Compile Sources, otherwise add it.
Also, if you use a xib file associated with it, make sure it is in Copy Bundle Resources.
