title: SwiftUI - Check If Image Exist
body: <p>I am attempting to execute code if an image exist.
  The issue is I am unable to capture the state of empty image call.
  The result is I get an empty image, but would rather put a placeholder image if possible.</p>
  
  <pre><code>   func procImage(inName: String) {
  
  
          switch (inName) {
  
          case inName:
              imageName = inName.lowercased()
  
          default:
              imageName = "blank"
          }
  
  
      }
  </code></pre>
