Backwards compatibility built on Xcode 9 to run on iPad version iOS 9.0

Question

I have an issue my original application that was built on iOS version 9.0, my new release is built using Xcode 9.2 i set deployment target to 9.0.to be backward compatible to older iPads.. App crashes on trying to save to core data ' Does not recognize Entity for name ' The Entity name is in my Core Data Stack , so I am not sure what is going on. Any guidance or ideas ?

Regards JZ

Hey JZ I know you asked this months ago - but see the answer to this question here: Xcode: iOS backward and forward compatibility for Deployment Target .

Apparently, you have to target the minimum OS you wish to support, as compatibility only runs forward for iOS development.
