Any CoreData experts know what could be going on here when trying to display to-many entity type relationship data? On initialisation my model does an fetch request for an entity called Expense, and some prefetching for related entities (to-many type) like this: request.relationshipKeyPathsForPrefetching = ["splits"] I was under the impression that calling a property on one of the related entities should fire the fault (if there is one) and give me the value. Here’s where it starts to go wrong. I have a property in my extension that I use in my detailed view: public var viewExpenseSplits: [ExpenseSplit] { return splits?.allObjects as? [ExpenseSplit] ?? [] } and then a list in my detail view: List(expense.viewExpenseSplits, id: \.self) { split in Text(split.amount ?? "") } Result: What's even more baffling is that I have no problem viewing these splits in the parent view. I thought perhaps I would have more luck passing the viewExpenseSplits through to the detail view instead of trying to access them from the Expense entity itself. Whilst I can print the data out when the view loads, my list still has the same problem. I thought this would be trivial. Can anyone point to me where I'm going wrong? Thanks!
