UIActivityViewController on iPad w… | Apple Developer Forums

For years a code for sharing something on iOS was something like this:

@IBAction func shareAll(_ sender: UIButton) {
  let text ="text..."
  let image = UIImage(named: "Product")
  let myWebsite = NSURL(string:"https://somelink.com")
  let shareAll= [text , image! , myWebsite]
  let activityViewController = UIActivityViewController(activityItems: shareAll, applicationActivities: nil)
  activityViewController.popoverPresentationController?.sourceView = self.view 
  self.present(activityViewController, animated: true, completion: nil)
  }

Well, it does not work on iPads with iOS13+ anymore unless we add

activityViewController.popoverPresentationController?.sourceRect = ...

I doubt that behaviour was intended. Old code still works on iPhones. Console trace is below:

[LayoutConstraints] Unable to simultaneously satisfy constraints.

Probably at least one of the constraints in the following list is one you don't want.

Try this:

(1) look at each constraint and try to figure out which you don't expect;

(2) find the code that added the unwanted constraint or constraints and fix it.

)

Will attempt to recover by breaking constraint
