title: Value stored in 'parameter name' is never read in commented Macro
body: <p>I'm using different Macros in order to log different sections of my app. This way I can "turn off" some of the logging using comments.</p>
  
  <p>Example:</p>
  
  <pre><code>String *logValue = @"This is some log text")
  </code></pre>
  
  <p>and then:</p>
  
  <pre><code>NetworkLog(@"%@", logValue);
  SessionLog(@"%@", logValue);
  </code></pre>
  
  <p>I can turn off all session logs in my app by commenting that specific Macro code and leaving the network logs active.
  When I turn off that specific Macro I get an analyzer warning:</p>
  
  <blockquote>
    <p>Value stored in 'logValue' is never read</p>
  </blockquote>
  
  <p>How can I solve this issue?</p>
