CoreData EXC_BAD_ACCESS (code=1, address=0x0) when access empty property

When I try to access an empty property after creating an NSManagedObject, it gives me a EXC_BAD_ACCESS (code=1, address=0x0)

let m = NSEntityDescription.insertNewObjectForEntityForName(entityName, inManagedObjectContext: context) as MyManagedEntity

println(m.numberProperty) // this is OK
println(m.stringProperty) // this gives me the exception
println(m.dateProperty) // this gives me the exception

Any Ideas how to solve it?

EDIT:

I'm also getting EXC_BREAKPOINT(code=EXC_I386_BPT, subcode-0x0) in my Tests when casting to MyManagedEntity

Did you specify default values for your attributes in your XCDataModel?

If you generate an NSManagedObject subclasses you can change any attribute to an optional by adding a question mark to the declaration:

@NSManaged var stringProperty: String?
@NSManaged var dateProperty: NSDate?

Elsewhere you can do:

println(m.stringProperty?)
if m.stringproperty != nil {
// do stuff
}
