# Summary:

When renaming a property using Xcode's refactoring tool, instance
variables that were automatically synthesized are not renamed.

# Steps to Reproduce:

Make a simple class with a property, and allow a backing instance
variable to be automatically synthesized.

    @interface Dog : NSObject
    @property (copy) NSString *name;
    @end

    @implementation Dog

    - (void)dealloc {
      [_name release];
    }

    @end

Now, rename `name` to `nickname` using the refactoring tool.

# Expected Results:

    @interface Dog : NSObject
    @property (copy) NSString *nickname;
    @end

    @implementation Dog

    - (void)dealloc {
      [_nickname release];
    }

    @end


# Actual Results:

    @interface Dog : NSObject
    @property (copy) NSString *nickname;
    @end

    @implementation Dog

    - (void)dealloc {
      [_name release]; <<< COMPILE ERROR: undefined identifier _name
    }

    @end


# Notes:

If an instance variable is in use, and the compiler can tell that it is
synthesized by the property in question, it should be renamed at the
same time as the property according to the rules that are used for
autosynthesis.
