Use Datepicker date as input to another view - swiftui

Question

Goal : use of selected date components of a datepicker as an input to a view where quotes from an external website are fetched.
Tried these approaches : using qDate:Date as parameter to init() for QuotesViewModel and QuotesView - but this approach seems to work only if parameter is struct/class.
Also tried to use #Binding variable but with no success.
Is there an elegant solution?
struct HomeView: View {
#State var qDate = Date()
var body: some View {
DatePicker("", selection: $qDate, displayedComponents: .date)
QuotesView()
}
}
struct QuotesView : View {
#ObservedObject var vm: QuotesViewModel
init() {
self.vm = QuotesViewModel()
}
var body: some View {
Text(vm.quote ?? "")
}
}
class QuotesViewModel: ObservableObject {
#Published var quote: String?
// Use Datepicker qDate components to create URL to fetch quote from external website.
}

Answer 1

If you pass a value into a view using the init, any external change to that value will result in the view being rebuilt:
struct HomeView: View {
#State var qDate = Date()
var body: some View {
DatePicker("", selection: $qDate, displayedComponents: .date)
QuotesView(quoteDate: qDate)
}
}
struct QuotesView: View {
let viewModel: QuotesViewModel
init(quoteDate: Date) {
self.viewModel = QuotesViewModel(quoteDate: quoteDate)
}
var body: some View {
Text(viewModel.quote)
}
}
class QuotesViewModel: ObservableObject {
#Published var quote: String
init(quoteDate: Date) {
//... Your external service
let quotes = ["Be yourself; everyone else is already taken.", "Try to be a rainbow in someone else's cloud."]
self.quote = quotes.randomElement() ?? ""
}
}
