SwiftUI - Pass Nested Array of Objects to Details View - arrays

Question

I'm trying to pass a data object that contains a nested array of objects from the Master view to the Details view. Currently, I'm able to display the parent level of the data object, but I'm struggling to try to figure out how to pass it's a nested array of data on to the details page. Below is a sample of my data model and how I'm going about displaying the information currently. I'm not sure what I need to type for the code where I'm passing the information on in the NavigationLink element. I'm sure there's probably a better way to do this, however, I'm just a designer trying to figure this out for prototyping reasons.

import Foundation
import SwiftUI
struct Passports: Identifiable {
let id : Int
let passportPremium: Bool
let passportActive: Bool
let passportTitle: String
let passportDates: String
let venues: [Venue]
}
struct Venue: Identifiable {
let id = UUID()
let title : String
let venueArea: String
let venueItems: [venueItem]
}
struct venueItem {
let title: String
let productDescription: String
let productPrice: Double

return [
Passports (
id: 1001,
passportPremium: false,
passportActive: true,
passportTitle : "Passport Title Example",
passportDates: "October 20 - November 3, 2019",

// PassportDetails //
struct PassportDetails: View {
var passportTitle = "Passport Name"
var venues: [Venue] = [
Venue(title: "Test Venue", venueArea: "Test Area", venueItems: [venueItem]())
]
var venueProd: [venueItem] = [
venueItem(title: "Test item", productDescription: "Test Description", productPrice: 9.99, productType: "Food", newStatus: false, mealPlan: true, kidApproved: false, vegetarian: false, glutenFree: false, featuredProduct: false, containsAlcohol: false)
]
var body: some View {

}.navigationBarTitle(Text(passportTitle))
}
}

Answer 1

In PassportDetails do the following:
var venues: [Venue]
and in Passports do this:
NavigationLink (destination: PassportDetails(passportTitle: item.passportTitle, venues: item.venues) )
PS: You should do the same for the passportTitle, meaning in PassportDetails put var passportTitle: String
