I'm starting with SwiftUI and I'm running into a roadblock with array items of an ObservableObject not saving to the main object.
Main object:
class Batch: Codable, Identifiable, ObservableObject {
let id: String
var items = [Item]()
}
Item object:
class Item: Codable, Identifiable, ObservableObject {
let id: String
var description: String
}
I have a BatchView which I pass a batch into:
struct BatchView: View {
@ObservedObject var batch: Batch
var body: some View {
List {
ForEach(batch.items) { item in
ItemView(item: item)
}
}
.navigationBarTitle(batch.items.reduce("", { $0 + $1.description }))
}
}
In the ItemView I change the description:
struct ItemView: View {
@ObservedObject var item: Item
@State private var descr = ""
var body: some View {
VStack(alignment: .leading) {
Text("MANUFACTURED")
TextField("", text: $descr) {
self.updateDescr(descr: self.descr)
}
}
}
private func updateDescr(descr: String) {
item.description = descr
}
}
But when I update the description for a batch item, the title of BatchView doesn't change, so the changes to the Item isn't coming back to the root Batch.
How do I make the above work?
