Is there any way to store unsigned long in core data?

Question

CoreData provides Integer 16, Integer 32 and Integer 64 storage, but doesn\'t support any sign qualifiers. You can store an unsigned int (32 bit) as a signed long (64 bit) a

Answer 1

An unsigned long is not 128bits (yet).
(or do you have a 128bits CPU?)

On a Mac, depending on your CPU architecture, it may be 32 or 64 bits.

See with:

NSLog( @"%u", sizeof( unsigned long ) );

So basically an unsigned long will be compatible will Integer32 or Integer64.
