How do I add a Fetched Property in XCode's Data Model Editor for minimum value of one attribute??
My model:
Item (name, note, storedItem)
StoredItem (price, item)
Item 1 ---> N StoredITem (1->N Relationship)
I want that Item has a fetched property named minPrice and its value is the minimum value setted for price in the storedItems.
Example:
Item1 (banana, storedItem1 ... storedItem4, 10)
StoredItem1 (10,item1)
StoredItem2 (15,item1)
StoredItem3 (30,item1)
StoredItem4 (54,item1)
What do I put in Destination?? StoredItem?
And what do I put in Expression??
