Cannot convert value of type 'Entity.Type' to expected argument type '[ElementRepresentable]'

[tanstaafl856]

Backing up and starting mostly over led me here...

EntityListSectionedTableVC [no loner REALLY a TavleViewController I guess] will sit beside and act as a selector for EntityDetailSectionedTableVC. I had that much working fine with JUST the default tableViews. Editing textFields in EntityDetailSectionedTableVC started retain cycle nightmares.

No Stroyboard. So no clear example found to indicate what I might be missing. .fromClass is as much as I have found to address it specifically. Guessing the HOW-TO section is missing some details or steps for the Storyboard free since going Storyboardless means handling a few things that normally just work? Or maybe something about the struct is causing problems? Any insights would be most appreciated. Thnx

just noticed that the variable used in the how-to was explicitly defined above as []. making a corresponding change had no effect on the error msg
