Answer 1

The popoverPresentationController sourceView needs to be set to current view.

let activityVC = UIActivityViewController(activityItems: [quoteController.attributedString, view.screenShot()], applicationActivities: [])
    
present(activityVC, animated: true)
activityVC.popoverPresentationController?.sourceView = view

Answer 2

The UIActivityViewController's has non-null popoverPresentationController property when running on iPad. So, try below.

if let wPPC = activityVC.popoverPresentationController {
    wPPC.sourceView = some view
    //  or
    wPPC.barButtonItem = some bar button item
}
presentViewController( activityVC, animated: true, completion: nil )
