I am studying using core data. Especially the fetchrequest is difficult.
Can't i save the last 7 values of a specific attribute of coredata in an array?
The goal is to use the charts package. I want to call 7 attribute values and express them in a chart.

It seems that is a similar question as one of your previous posts.
Define an array of values of the specific attribute var storedData : [MySpecificAttribute] = []
each time you update in Core Data, append the new value to the array.
If you have more than 7 items, remove items from the start till you have 7 items left.
