Infinite loop with TextField on iOS 15

[bogdan-pechounov]

How frequently does the bug occur?

Sometimes

Description

When I type on a suggestion in the keyboard, sometimes the UI freezes because of an infinite loop, or I get a Binding<String> action tried to update multiple times per frame.. This happens on the "iPhone SE (1st generation) - iOS 15.0" emulator inconsistently. On my physical device running iOS 15.7.8, it seems to always happen. It doesn't seem to happen for iOS 16.

(UI is frozen after pressing the "Imagine" suggestion)

Stacktrace & log output

There is no crash. I added let _ = print(item.name) and the name keeps being printed.

Can you reproduce the bug?

Reproduction Steps

1. Add an item
2. Focus on the item
3. Select a suggestion on the mobile keyboard
4. Sometimes the error doesn't happen on the first try, in which case run the app again

struct ContentView: View {
    var body: some View {
        ItemsView2()
    }
}

import SwiftUI
import RealmSwift

class Item2: Object, ObjectKeyIdentifiable {
    @Persisted(primaryKey: true) var _id: ObjectId
    @Persisted var name: String
    @Persisted var order: Int
}


struct ItemsView2: View {
    @ObservedResults(Item2.self, sortDescriptor: SortDescriptor(keyPath: "order", ascending: true)) var items // maybe the sorting is the cause
    
    var body: some View {
        NavigationView {
            // List
            List {
                Section {
                    ForEach(items) { item in
                        ItemView2(item: item)
                    }
                    .onDelete(perform: $items.remove)
                    
                    // Add
                    Button("Add") {
                        let item = Item2()
                        item.order = (items.max(of: \Item2.order) ?? 0) + 1
                        $items.append(item)
                    }
                }
            }
        }
    }
}

struct ItemView2: View {
    @ObservedRealmObject var item: Item2
    
    var body: some View {
        
        let _ = print(item.name)
        
        HStack { // not sure if it makes a difference
            TextField("Item", text: $item.name)
        }
    }
}
