title: Fast Enumeration error?
body: <p>Getting a warning saying that:</p>
  
  <p>Collection expression type 'NSString *' may not respond to 'countByEnumeratingWithState:objects:count'</p>
  
  <p>when trying to run the following code:</p>
  
  <pre><code> NSString *proper = [NSString stringWithContentsOfFile:@"usr/share/dict/propernames"     encoding:NSUTF8StringEncoding error:NULL];
  
  
  for (NSString *i in proper){
          NSLog(@"Item&gt;%@", i);
          }
  </code></pre>
  
  <p>When I run the program I don't get any output from the NSLog statement. Anyone run into this? </p>
