iOS - Implicit coercion to 32 bits in the database is not recommended

Question

All,

Please help, I think I am going mad, but I have an existing app which is designed for 32bit standard device. However, when I run on 64bit it's having problems, I am getting the following:

CoreData: warning: Property 'jobId' is a 64 bit scalar type on class 'JobSummary' 
that does not match its entity's property's 32 bit scalar type.  
Implicit coercion to 32 bits in the database is not recommended.

jobId is NSInteger

Is their something I need to do for it to work in both? Currently it's one or the other.

The problem is that `int`, `NSNumber`, et al, are whatever they want to be. They change from platform to platform and are effectively non-portable. — Hot Licks, Aug 28 '14 at 11:29

In Swift you can use something like this:

@NSManaged var jobId: Int32

It works fine on both 32bit and 64bits devices.

If it is feasible, transform your scalar values to objects, i.e. NSNumber. In the new model version, make sure you int types are what you need (making them bigger in case you are not sure).
