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
