Does not conform to protocol BindableObject - Xcode 11 Beta 4

Question

Playing around with examples out there. Found a project that had a class that was a bindableobject and it didn\'t give any errors. Now that Xcode 11 beta 4 is out

Answer 1

in Xcode 11.X, I verify is fine in Xcode 11.2.1, 11.3.

BindableObject is changed to ObservableObject.

ObjectBinding is now ObservedObject.

didChange should be changed to objectWillChange.

List(dataSource.pictures, id: .self) { }

You can also now get rid of the did/willChange publisher and the .send code and just make pictures @Published

The rest will be autogenerated for you.

for example:

import SwiftUI
import Combine
import Foundation

class RoomStore: ObservableObject {
    @Published var rooms: [Room]
    init(rooms: [Room]) {
        self.rooms = rooms
    }
}

struct ContentView: View {
    @ObservedObject var store = RoomStore(rooms: [])
}
