I m trying to have a table column to display the sum of child values using the IB. I m not sure if this is doable though.
So I have my Core Data bind to a table and a column of "total sales amount" that should be a total of the sales of the parent object.
I m trying to do it like this:
"departments.@distinctUnionOfSets.sales.@sum.amount" in the "Model Key Path" of the Table Column Binding in IB.
Is there any example or tutorial on how to do this.
