SwiftUI holding reference to deleted core data object causing crash

Question

Im finding it impossible to use core data with SwiftUI, because as I pass a core data to a view observed object variable, the navigation link view will hold a reference to the o

Answer 1

A view modifier for this (based on conditional view modifiers):

import SwiftUI
import CoreData

extension View {
    @ViewBuilder
    func `if`(
        _ condition: Bool,
        transform: (Self) -> Transform
    ) -> some View {
        if condition {
            transform(self)
        } else {
            self
        }
    }
}

extension View {
    func hidingFaults(_ object: NSManagedObject) -> some View {
        self.if(object.isFault) { _ in EmptyView() }
    }
}

Having said that, it's worth checking you're performing CoreData operations asynchronously on the main thread, doing it synchronously can be a source of grief (sometimes, but not always).
