My Mac "Designed for iPad"

I am trying to adapt an iOS application to use the “Designed for iPad” schema on my M1 Mac
Everything seems to work EXCEPT clicking a cell in a UITableview

 internal func tableView(_ tableView: UITableView,didSelectRowAt indexPath: IndexPath) {

never fires when running on a Mac, but works perfectly on Iphone/iPad

So far can find hardly ANY information about this mode on the 'Net

as a “BAND-AID” I added a SingleTap … which seems to work, don’t know why it is required :frowning:

let singleTapGesture: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(gameSngTap(_:)))
 singleTapGesture.numberOfTapsRequired = 1  // add double tap

 @objc func gameSngTap(_ gesture: UITapGestureRecognizer) {
let pointInTable      : CGPoint   = gesture.location(in: tblGAMES)
let selectedIndexPath : IndexPath = tblGAMES.indexPathForRow(at: pointInTable)!
tblGAMES.selectRow(at: selectedIndexPath, animated: false, scrollPosition: .none)
tblGAMES.delegate?.tableView!( tblGAMES, didSelectRowAt: selectedIndexPath)
