You’ll need an actual type to contain the raw JSON. Hilariously, I have to wonder if Argo’s JSON enum could be made Decodable, as it can represent every valid JSON type typically contained in the Any returned by JSONSerialization. Yet another reason why Swift needs a real JSON serialization.<div class=""><br class=""></div><div class=""><br class=""></div><div class="">Jon Shier<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Jun 17, 2017, at 10:07 PM, Chris Anderson via swift-users <<a href="mailto:swift-users@swift.org" class="">swift-users@swift.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html charset=utf-8" class=""><div style="word-wrap: break-word;
