title: Swift string format specifier equivalent to %@
body: <p>I am writing a simple app with a form in Swift, I had the app written in Objective-C to populate an e-Mail with data from text fields in a view, I used the following code to do this:  </p>
  
  <pre class="lang-c prettyprint-override"><code>NSString *messageBody = [NSString stringWithFormat:@"Name: %@ \nDate: %@", NameField.text, DateField.text];
  </code></pre>
  
  <p>I am trying to achieve the same thing in Swift, I have the following so far:</p>
  
  <pre class="lang-swift prettyprint-override"><code>let messageBody = NSString(format: "Name: %@ \nDate: %@", NameField, DateField)
  </code></pre>
  
  <p>I am looking for swifts equivalent to <code>"%@"</code> to make the app look to the format of the string to find the data to place after <code>"Name:"</code>.</p>
