  <pre><code>runtime: SwiftUI: No image named '' found in asset catalog for main bundle (/Users/yun/Library/Developer/CoreSimulator/Devices/623B1BB3-5C34-4311-AA41-86C42FE27439/data/Containers/Bundle/Application/8E87B349-36CA-41B8-A34C-02BBB2F00472/Travel.app)
  </code></pre>
  <p>The image doesn't have a name, just <code>''</code>, so I can't find the cause of the error.</p>
  <pre><code>//  AppDelegate.swift &lt;br&gt;
  class AppDelegate: UIResponder, UIApplicationDelegate { &lt;-- this is the break point...
  </code></pre>
