Heeeelp!
What does the following error mean, and how do I fix it? It happens, when I call `modelContext.save()` in a SwiftUI view.
"SwiftData/ModelCoders.swift:105: Fatal error: Composite Coder only supports Keyed Container”
Edit: Solved! It appears SwiftData does not support Duration properties in models. Changing it to a TimeInterval instead fixes it.
