SwiftUI can you have a view in a loop?

Question

In the app I am developing, I have multiple (23) screens that are the almost the same. They differ by a picture. The data for all of these can be kept in an array [String]. I tried calling a NavigationView (separate screen) inside a for loop but couldn't get it to work. Should this be possible? Is there any examples out there?

You can try and pass through 2 things between the views.

count too keep a track of each view and a array to keep a track of each of the information inside of the view.

Here would be a somewhat example:

import SwiftUI

struct ContentView1: View {
    @State private var count = 0
    @State private var info = ["a", "b", "c"]
    var body: some View {
        VStack {
            Text("View 1")
            Text("Content: a")
            NavigationLink(destination: ContentView2(count: count + 1, info: info)) {
                Text("Next")
            }
        }
    }
}

struct ContentView2: View {
    var count: Int
    var info: [String]
    var body: some View {
        VStack {
            Text(count)
            Text(info: info[count]
            NavigationLink(destination: ContentView3(count: count + 1, info: info)) {
                Text("Next")
            }
        }
    }
}

struct ContentView3: View {
    var count: Int
    var info: [String]
    var body: some View {
        VStack {
            Text(count)
            Text(info: info[count]
        }
    }
}
