I'm experiencing an issue in my iOS app where tapping to select text in a UITextView that is embedded within a UIScrollView causes the scroll view to jump to an incorrect position. This problem seems to occur only on iOS 15. Does anyone know how to fix this issue, or is there a known bug regarding this behavior on iOS 15?
class ViewController: UIViewController, UITextViewDelegate, UIGestureRecognizerDelegate {
@IBOutlet weak var textView: UITextView!
@IBOutlet weak var scrollView: UIScrollView!
override func viewDidLoad() {
super.viewDidLoad()
textView.isScrollEnabled = false
textView.layoutManager.allowsNonContiguousLayout = false
}
}

I am currently developing an Share Extension for iOS and have run into an issue where the NSExtensionActionWantsFullScreenPresentation attribute doesn't seem to be working as expected. I've set this property to true in my Info.plist
I have a question regarding the Live Activities feature introduced in iOS 16.1.
According to the documentation, Live Activities can be updated via push notifications. However, I am curious to know if Live Activities can still receive updates via push notifications when push notification permissions are turned off for an app.
Could you please clarify whether Live Activities updates are independent of the push notification permissions setting, and if so, how the update mechanism works in this scenario?
Thank you for your assistance.
Best regards,
