title: Check empty string in Swift?
body: <p>In Objective C, one could do the following to check for strings:</p>
  
  <pre class="lang-c prettyprint-override"><code>if ([myString isEqualToString:@""]) {
      NSLog(@"myString IS empty!");
  } else {
      NSLog(@"myString IS NOT empty, it is: %@", myString);
  }
  </code></pre>
  
  <p>How does one detect empty strings in Swift?</p>
