Send data to next view - SwiftUI - view

Question

So I have been trying to get a simple pass of data working with SwiftUI.
Basically the below script prints out a list of items (in a HStack) I then have each one linked to our Podcast() view.
What I am trying to do is pass through the podcast name to the next view. How do I achieve
this? As all the examples are about int which I am not using am using a String.
import SwiftUI
import RemoteImage
struct ContentView: View {
#State private var showAlert = false
#State var posts: [Program] = []
var body: some View {
NavigationView {
if posts.isEmpty {
Text("Loading")
} else {
ScrollView(.horizontal, showsIndicators: false) {
HStack(alignment: .bottom, spacing: 10) {
ForEach(posts) { post in
//return
NavigationLink(destination: Podcasts()){
RemoteImage(type: .url(URL(string:post.icon)!), errorView: { error in
Text(error.localizedDescription)
}, imageView: { image in
image
.resizable()
.renderingMode(.original)
/* .clipShape(Circle())
.shadow(radius: 10)
.overlay(Circle().stroke(Color.red, lineWidth: 5))*/
.aspectRatio(contentMode: .fit)
.frame(width:200, height:200)
}, loadingView: {
Text("Loading ...")
})
}
}
}.frame(height: 200)
}.frame(height: 200)
}
}.onAppear {
Api().getPosts { (posts) in
self.posts = posts
}
}.navigationBarTitle(Text("Home"))
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
The podcast View
import SwiftUI
struct Podcasts: View {
var body: some View {
NavigationView{
Text("Hello")
}.navigationBarTitle(Text("Podcast"))
}
}
struct Podcasts_Previews: PreviewProvider {
static var previews: some View {
Podcasts()
}
}

Answer 1

Pass post as constructor argument, like
ForEach(posts) { post in
//return
NavigationLink(destination: Podcasts(post: post)){
so now
struct Podcasts: View {
let post: Program
var body: some View {
// !! DON'T ADD SECOND NAVIGATION VIEW IN STACK
// !! - THERE MUST BE ONLY ONE
Text(post.name)
.navigationBarTitle(Text("Podcast"))
}
}
