Hi, newbie here, does anyone experienced this kind of error? Got stuck here for several days and I already deleted the view controller too. The code is already edited too. Thanks! 2023-08-29 21:08:16.289593+0700 DoctorPlus[9766:4653867] [Storyboard] Unable to find method -[(null) UserAgreementVC]

Hi all! Im still new in apple development and was wondering about this. So i have this app template that runs in iOS 15. As Apple has upgraded to iOS16, I was wondering if that iOS15 app can run in iOS16 or should I downgrade the iOS version? also, my XCode is in version 14 ish, so can it support iOS15 too? As i need to customize the template. I appreciate your time to read (and hopefully answer this) Thank you!
