We've successfully converted our app to the new Unified API and submitted it to the App Store, but I still get a mail from Apple concerning missing 64 bit support in the app.
After I checked, I seem to need to explicitly enable 64 bit support in the iOS Build settings, however, there is no such entry in Visual Studio (only ARMv7 and ARMv7s) :-( I have all the latest (stable) updated installed:
Xamarin 3.9.289.0
Xamarin.iOS 8.6.1.0
Xamarin.iOS Unified Migration 1.0
I have Visual Studio 2012, and cannot change that at the moment. Also, I have converted the app manually, not using the migration wizard. Please advise, this is urgent. Thanks!
