iOS 16 & AGSPopupsViewController

Question

Just noticed with iOS 16 the AGSPopupsViewController is not working correctly. I have a UINavigationController displaying in a popover view with a table view of map features. Clicking on a feature will push theAGSPopupsViewController for the selected feature. This worked fine until iOS 16. Now after the AGSPopupsViewController is pushed, the popover view jumps randomly to a different point. Anyone else experiencing this?

Basic code snippet that is not working:

let popupsViewController = AGSPopupsViewController(popups: item.popups, containerStyle: .navigationController)
popupsViewController.modalPresentationStyle = .formSheet
popupsViewController.preferredContentSize = CGSize(width: 500, height: 600)
popupsViewController.modalPresenter = self.tappedFeatureNavController?.topViewController
popupsViewController.delegate = self

// Present the popup.
// NOTE: Bug with iOS 16 breaks popover causing it to lose its anchor point and get cut off.
self.tappedFeatureNavController?.pushViewController(popupsViewController, animated: true)

Thanks Mark!  I did some more testing and it looks like the issue has to do with dynamic sizing of the popovers. When the popover first appears, it is sized to fit the number of results in the table view. Then when an item is selected, the AGSPopupsViewController is pushed but at a size to fit its content. If I remove the resizing elements, it works just like your example. I will see if there is something in the sizing that is causing the issue.

Thanks for you help!

I created a similar scenario, based on your information.  It seems to be working for me, but let me know if this mimic's your situation.  The items in the list view are `AGSPopup`s.  They don't have a title, so I'm simply using the "popup.geoElement.geometry.description" as the text in the table view cell.  Tapping on a row creates a new "AGSPopupsViewController" with a single Popup and then pushes it onto the navigation stack:  "navigationController?.pushViewController(popupsViewController, animated: true)"

I'm using Xcode 14 and the iPad Pro (9.7-inch) iOS 16 simulator.

Let me know how well this matches your code; if you are able provide some code that reproduces the issue in a simple project, that would help.

Thanks for the reply Mark!

A little more clarification:

* We are seeing the issue on devices (phone and tablet) and simulator.
* Control hierarchy* We have a AGSMapView displaying a webmap with features
* Additional operational layers are added to the webmap to display additional graphics
* Tapping on the map view runs an identify on all the layers,
* A UINavigationController is used to display a popover, anchored to the tap point
* A UITableviewController with identified items from map tap is displayed in the popover. These could be webmap features as well as graphics from the added operational layers.
* Tapping on one of the identified items, in the table view, triggers the code from previous post.
* Once the AGSPopupsViewController is pushed, the popover jumps and anchors to the edge of the AGSMapView.

FYI: It appears to be an issue with the transition/animation of the nav controller push. Setting animate to false does not create the issue.

Thanks!
