title: iOS - UserDefaults Source File Replacement
body: <p>I'm implementing backup functionalities in my app. Therefore I am backing up the UserDefaults source file where all UserDefaults are saved at the following path:</p>
  
  <pre><code>.../Library/Preferences/&lt;Bundle Identifier&gt;.plist
  </code></pre>
  
  <p>When the user restores a backup I'm replacing this file with the backup file. </p>
  
  <p><strong>Problem:</strong> The app continues to use the old UserDefaults. Only when I restart the app the changes apply. 
  How can I tell Xcode to load the source file again? </p>
