Remarks

IBOutlet is neither a reserved word nor a variable or class, is syntactic sugar for Interface Builder. After the Objective-C source code is pre-processed it is resolved to nothing.

In Swift it's resolved as nil.

It's declared in <UIKit/UINibDeclarations.h> as

#ifndef IBOutlet
#define IBOutlet
#endif
