Part of a Feedback to apple on what I want from the new FetchRequest struct in SwiftUI
@Environment(\.managedObjectContext) var managedObjectContext
@State var year = "1880"
@State var ascending = true
@State var someValue = "value"
@FetchRequest(
entity: YearOfBirth.entity(),
sortDescriptors: [NSSortDescriptor(key: "year", ascending: ascending.wrappedValue)],
predicate: NSPredicate(format: "%K = %@", “someAttributeKey”, someValue.wrappedValue)
) var years: FetchedResults<YearOfBirth>

It isn't hard to find some numbers that will cause SwiftUI to break down a little
struct Item: View, Identifiable {
let forInt: Int
var id: String {
return "\(forInt)"
}
var body : some View {
//: Make this view more complex
HStack{
Text("\(forInt)")
}

A sneaky addition, we can use generics to help us write this initializer for all types of Nameable
struct NameHolder: Nameable {
var id: String { return name }
var name: String
init<U>(nameable name: U) where U: Nameable {
self.name = name.name
}
}
