Singleton release method produces warning?

Question

In my singleton release method, I have it doing nothing:

-(void) release {
  //A whole lot of nothing.
}

But it produces this warning:

Answer 1

In NSObject.h, the definition of the release method returns a oneway void.

The oneway keyword is used for distributed objects.

Since Xcode4.2 and LLVM, checkings are more strong and if it was accepted by previous versions of Xcode or by gcc, you now need to add this oneway keyword so that the LLVM compiler stops warning about this.

-(oneway void) release { /* do nothing */ }

This won't have any incident on your code.
