@YashvitNaik I would agree with Michael and if you are starting something new look at MAUI. I think you can use with the Core 8 preview.
Xamarin is basically already out of support by Microsoft. At this point they are not showing any indication of releasing an official Xamarin.iOS library to support XCode 15. The latest official Xamarin.iOS library only support XCode 14 which targets iOS <= 16.x. As iOS 17 is already out, Xamarin no longer supports the latest iOS devices or ones that have been updated.
