This post is from the WWDC26 SwiftData Q&A.

Hi, does SwiftData supports aggregate functions through NSExpression for operations like SUM, AVG, MIN, and MAX?

Hello @Frameworks Engineer @cgontijo,

I filed feedback for that in January 2024.

Basically, the equivalent to NSExpression functions like sum/average/max/median.

Feel free to check them. It's blocking me from adopting SwiftData because I can't do any operation on my data set as I have to fetch all objects into memory with SwiftData.
