  <p>In <code>Objective-C</code> we do like</p>
  
  <pre><code>NSString *string = @"Swift";
  NSString *resultStr = [string stringByAppendingString:@" is a new Programming Language"];
  </code></pre>
  
  <p>or</p>
  
  <pre><code>NSString *resultStr=[NSString stringWithFormat:@"%@ is a new Programming Language",string];
  </code></pre>
