I’m trying to filter results to get all characters that are associated with a story. When navigating to the view it filters as it should, but as soon as you select the Add Character option, the app just freezes.

I’ve found that if I comment out the Query line in the init, and filter out as part of the foreach I don’t get the freeze.

Can anyone advise how I should be doing these predicates as it seems init isn’t the best place to do it

The views code is

import SwiftUI
import SwiftData

struct CharacterListView: View {
    let story : Story
    @Query(sort: Character.name, order: .forward) private var characters: [Character]
    
    var body: some View {
        List {
            ForEach(characters) { char in
                CharacterListCellView(char: char)
            }
        }
        .toolbar {
            ToolbarItem {
                NavigationLink(destination: CharacterAddView(story: story)) {
                    Label("Add Character", systemImage: "plus")
                }
            }
        }
        .navigationBarTitle("Characters", displayMode: .inline)
    }
    
    init(story: Story) {
        self.story = story
        
        let id = story.persistentModelID
        let predicate = #Predicate<Character> { char in
            char.story?.persistentModelID == id
        }
        
        _characters = Query(filter: predicate, sort: [SortDescriptor(.name)] )
    }
}
