how to check for non used variables in Xcode 4

I am wondering if there is an option in xcode that will let you debug a variable to see if it's being used in your code anywhere?

I find sometimes I make changes to my code, then I look at all of my synthesised variables and I'm just not positive that they are being used.. I don't mind going through my code and checking but I thought it would be more productive if their was a function that would help me do this quicker?

Dose anyone know of such a thing?

If you switch the compiler to LLVM/GCC or just LLVM, then run "Analyze" (CMD+SHIFT+I I think, might be CMD+SHIFT+J) it will put a warning next to any unused variables/ivars/properties.

Product -> Analyze will also show variables that are not read, which sometimes can capture more unused variables.

You can set the Unused parameter warnings in the Build Settings of your project. Just search "Unused" when looking for the option.
