I made a program for iOS 8 and later. But the program does not work on iOS 9 . Although checked repeatedly opening and closing programs. What do you think could be the reason ?
It could be anything. Have you tried running with the debugger? Have you checked the crash logs? Without any of that all we can do is guess.
Thank you for answer
How can I do what you say this ? Could you help? Xeme programming 've just begun
There's quite a bit of information available here on the site. Check http://developer.xamarin.com/guides/ios/deployment,_testing,_and_metrics/debugging_in_xamarin_ios/ for a guide to using the Xamarin.iOS debugger.
