I’m working with SwiftData for the first time and having trouble with crashes when I try to set the value of a relationship.

I created a small sample app for saving and loading a tree using SwiftData, basically following this post. how-to-create-a-list-with-children-tree-from-swiftdata-model

In SwiftData I can’t get delete(model:where:includeSubclasses:) method to work. In the code example below I would expect both the School and its students to be deleted because of the cascade delete rule.

Given the code below the students array on the school is not being updated. Why?

I’m still working on my version 1.0.0 of my app so don’t yet need to migrate versions. I would like to rename my data model(s) but I get this error when running the app after changing the name of the model from SectionsSD to HelpSection

There’s this function in file Quake+GeoFeatureCollection.swift:
