I have made a basic single view app (objective-c) in XCode 8.2.1 targeted to iOS 8.0, imported the MoPub SDK (4.12.0), added lines to the viewcontrollers .h and .m files as per the instructions, plugged in my Ad Unit Id and tried to build. This produces 23 warnings, including several about deprecation and semantic issues. Is this normal or am I missing something? If I target to iOS 10 the number increases to 79.
