    I could only find a list of the variable types from Ken Orr’s “Debugging with Xcode” WWDC 2012 presentation slides (Session 412). You may, or may not, have access to these slides.

    • L: Local Variable
    • A: Argument
    • S: Static Variable
    • V: Global Variable (Darker)
    • R: Register
    • V: Instance Variable (Lighter)
    • E: Expression

    Note: I cannot be more specific about the different colours of the ‘V’ variables as I am colour-blind. Boo hoo, poor me. Perhaps you can tell me?
