I have not received any response from Apple's engineering team. I will let them know that you are having the same problem with UIKit.

Following the response from Technical Support, I filed a bug report with Feedback Assistant. According to Technical Support, OS or framework fix is probably needed. If we have further information, we will share it.

Thank you for your comment. Unfortunately, this issue has not yet been resolved and we are inquiring with TSI. When we get an answer we will share it with you.

Is your workaround still valid for iOS17? After updating to iOS17, my app now works smart selection even when the PKToolPicker is not displayed. I would like to know how to disable smart selection on iOS17.
