Xcode: 11.4.1~

    ...
    var testDict: [String: Double] = ["USD:": 10.0, "EUR:": 10.0, "ILS:": 10.0]
    ...
    ForEach(testDict.keys.sorted(), id: \.self) { key in
        HStack {
            Text(key)
            Text("\(testDict[key] ?? 1.0)")
        }
    }
    ...

more detail:

final class ViewModel: ObservableObject {
    @Published
    var abstractCurrencyCount: Double = 10
    @Published
    var abstractCurrencytIndex: [String: Double] = ["USD:": 10.0, "EUR:": 15.0, "ILS:": 5.0]
}

struct SomeView: View {
    @ObservedObject var vm = ViewModel()
    var body: some View {
        NavigationView {
            List {
                ForEach(vm.abstractCurrencytIndex.keys.sorted(), id: \.self) { key in
                    HStack {
                        Text(String(format: "%.2f", self.vm.abstractCurrencyCount))
                        Text("Abstract currency in \(key)")
                        Spacer()
                        Text(NumberFormatter.localizedString(from: NSNumber(value: self.vm.abstractCurrencytIndex[key] ?? 0.0), number: .currency))
                    }
                }
            }
        }
    }
}
