title: xcode filter NSMutableArray elements by string contents
body: <p>I would like to filter NSMutableArray elements that contains "some" string. ListArchives is filled with string elements and listFiles must be a filtered one. XCode generates an alert at last posted line. What am doing wrong? any other method to filter elements of NSMutableArray? </p>
  
  <pre><code>NSString *match = @"*some*"; 
  listFiles = [[NSMutableArray alloc] init];
  
  NSPredicate *sPredicate = [NSPredicate predicateWithFormat:@"SELF like[cd] %@", match];
  
  listFiles = [listArchives filteredArrayUsingPredicate:sPredicate];
  </code></pre>
