Drop target no longer highlighting when compiling with Xcode 12

The drop target I've been specifying in iOS 13 no longer highlights in iOS 14, but only when compiled with Xcode 12.x.

When I return

Code Block
UITableViewDropProposal(operation: .move, intent: .insertIntoDestinationIndexPath)

from

Code Block
optional func tableView(_ tableView: UITableView, dropSessionDidUpdate session: UIDropSession, withDestinationIndexPath destinationIndexPath: IndexPath?) -> UITableViewDropProposal


the table view row at the index path no longer highlights as blue. Other intents are still working fine.

Is this an intended change in the behavior of the iOS 14 SDK, do I need to do something new, or is it a UIKit bug?

I'm also having this issue. have you found a solution? I'm using Xcode 12.5.1 and I see the issue on both simulators and devices. my iOS deployment target is 13.3
