title: Value stored to NSString during its initialization is never read
body: <p>In my iOS app I have following code:</p>
  
  <pre><code>case SASpeechSubCase03:
  {
       SAActivity currentActivity = self.mediator.selectedActivity;
  
       NSString *sActivity = NSLocalizedString(@"activity", @"activity");
       NSString *sActivity2 = NSLocalizedString(@"another activity", @"another activity");
       if(currentActivity == SAActivityWalk)
       {
          sActivity = NSLocalizedString(@"walk", @"walk");
          sActivity2 = NSLocalizedString(@"walking", @"walking");
       }
       else
       {
          sActivity = NSLocalizedString(@"run", @"run");
          sActivity2 = NSLocalizedString(@"jogging", @"jogging");
       }
  
       return [NSString stringWithFormat:speech.text, sActivity, sActivity2];
  
       break;
  }
  </code></pre>
  
  <p>When I run bots on it, it gave me following warning:</p>
  
  <blockquote>
