SwiftUI: assign binding variable from json parsed object - swift

Question

I am trying to assign a value I fetch and parse from JSON to another view.
struct ContentView: View {
#State private var showAlert = false
#State private var showAbout = false
#State private var showModal = false
#State private var title = "hi"
#State private var isCodeSelectorPresented = false
#ObservedObject var fetch = FetchNovitads()
var body: some View {
VStack {
NavigationView {
List(fetch.Novitadss) { Novitads in
VStack(alignment: .leading) {
// 3.
Text(Novitads.name!.de)
.platformFont()
.fontWeight(.black)
Text(Novitads.textTeaser.de)
.platformFont()
.fontWeight(.medium)
.onTapGesture {
self.showModal.toggle()
// 3.
}.sheet(isPresented: self.$showModal) {
ModalView(showModal: self.$showModal,
title: self.$title)
}
In this sample code the title (defined as "hi") is passed correctly.
What I want to do however is to assign the value of Novitads.name!.de to the title variable so that I can use it in the modal view.

Answer 1

I just display self.$title in the ModalView Text("(String(title))")
Then you don't need binding here and pass value directly, like
ModalView(showModal: self.$showModal, title: Novitads.name!.de)
and your ModalView declaration be as
struct ModalView: View {
#Binding showModal: Bool
let title: String
/// .. all other your code
}
Note: #State private var title = "hi" can be removed at all

Answer 2

try assigning the title like this:
struct ContentView: View {
struct ContentView: View {
#State private var showAlert = false
#State private var showAbout = false
#State private var showModal = false
#State private var title = "hi"
#State private var isCodeSelectorPresented = false
#ObservedObject var fetch = FetchNovitads()
var body: some View {
VStack {
NavigationView {
List(fetch.Novitadss) { Novitads in
VStack(alignment: .leading) {
// 3.
Text(Novitads.name!.de)
.platformFont()
.fontWeight(.black)
Text(Novitads.textTeaser.de)
.platformFont()
.fontWeight(.medium)
.onTapGesture {
self.showModal.toggle()
// 3.
}.sheet(isPresented: self.$showModal) {
ModalView(showModal: self.$showModal, title: self.$title)
}
}
}
}
}.onAppear(perform:{ self.title = self.fetch.Novitads.name!.de })
}
