inverse relationship to many entities in core data
===

<br />
I have two entities: 'A' and 'B'. 'A' entity have few relationship to ONE! inverse relation in 'B' entity. <br />
For example:<br />
 `a.ralation_1` <---> destination: `b.some_elem_1` inverse: `b.inverse_relation` <br />
 `a.ralation_2` <---> destination: `b.some_elem_2` inverse: `b.inverse_relation` <br />
 `a.ralation_3` <---> destination: `b.some_elem_3` inverse: `b.inverse_relation` <br />
Is this normal? Somewhere XCode show me warning, but in some relationship it's ok. What is the better way to do those 'relationship'? <br />
Thanks.
