            You use the wrong source for showing the selected item. As the shortened list is not the same as adfl, you should not use adfl inside sauthor_list(). You need to get the selected item using frame1_lb.get() instead:

            Forget SwiftyJSON, it's a great library but it's outdated.
            And forget also a struct with static properties as data source.

            Decode the JSON with Decodable – AlamoFire does support it – and group the array with Dictionary(grouping:by:) into sections.

            First create two structs, a struct for the sections and one for the items (User in the following example)
