title: NSKeyedUnarchiver _warnAboutNSObjectInAllowedClasses error log in iOS console logs fault
body: <ol>
  <li>Run my iOS App on a simulator, or real device</li>
  <li>Open the Console.app in MAC</li>
  <li>Force quit and relaunch the app</li>
  <li>Check the logs</li>
  </ol>
  <p>I see this logs appearing as a &quot;Fault&quot;, but I have no idea where it comes from, and I could NOT find any information from Apple as well.
  Has anyone seen this error before?
  Where should I start to debug it?
  What does it even mean?
  Please please help thank you!!!</p>
  <p><code>*** -[NSKeyedUnarchiver _warnAboutNSObjectInAllowedClasses]: NSSecureCoding allowed classes list contains [NSObject class], which bypasses security by allowing any Objective-C class to be implicitly decoded. Consider reducing the scope of allowed classes during decoding by listing only the classes you expect to decode, or a more specific base class than NSObject. This will be disallowed in the future.</code></p>
