How to separate Global Store

MultiStores.swift

import SwiftUI
import PlaygroundSupport

class GlobalStore: ObservableObject {
    static let shared = GlobalStore()

    private init() {}

    @Published var api1 = Api1Store()
    @Published var api2 = Api1Store()
}

class Api1Store {
    var field = ""
}

class Api2Store {
    var field = ""
}

struct Test: View {
    @ObservedObject var store = GlobalStore.shared
    
    var body: some View {
        VStack {
            TextField("api1 field", text: $store.api1.field)
            TextField("api1 field", text: $store.api1.field)
            Divider()
            TextField("api2 field", text: $store.api2.field)
            TextField("api2 field", text: $store.api2.field)
        }
    }
}


let viewController = UIHostingController(rootView: Test())
PlaygroundPage.current.liveView = viewController
