我正在尝试在列表视图中显示顶级数组中的元素。数据模型的构造方式是，它是一个事件数组，然后在该数组中，存在一个与各个事件相关联的场所。

在主视图中，我知道如何通过索引显示单个事件的标题，但是我不确定如何使用ForEach列出所有不同的事件。

Passports.swift（数据模型）

import Foundation
import SwiftUI


struct Passport: 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
    let productType: String
    let newStatus: Bool
    let diningPlan: Bool
    let kidFriendly: Bool
    let vegetarian: Bool
    let glutenFree: Bool
    let featuredProduct: Bool
    let containsAlcohol: Bool
}


extension Passport {
    static func all() -> [Passport] {
        return [
                Passport (
                    id: 1001,passportPremium: false,passportactive: true,passportTitle : "Event 1",passportDates: "October 20 - November 3,2019",venues: [
                        Venue (
                            title: "Bavaria Holiday Kitchen",venueArea: "Germany Pavilion",venueItems: [
                                venueItem (
                                    title: "Potato Dumpling",productDescription: "Potato Dumpling with Mushroom Sauce",productPrice: 0.00,productType: "Food",newStatus: false,diningPlan: false,kidFriendly: true,vegetarian: false,glutenFree: false,featuredProduct: false,containsAlcohol: false
                                )
                            ] // End VenueItems
                        ) // End Venue
                    ] // End Venues
                ),Passport (
                               id: 1002,passportTitle : “Event 2“,venues: [
                                   Venue (
                                       title: "Bavaria Holiday Kitchen",venueItems: [
                                           venueItem (
                                               title: "Potato Dumpling",containsAlcohol: false
                                           )
                                       ] // End VenueItems
                                   ) // End Venue
                               ] // End Venues
                           )// End Individual Passport

                ] // End Return

    }

}

PassportsView.swift

import SwiftUI

struct PassportsView: View {

    var model = Passports.all()

    var body: some View {
        NavigationView {
            ForEach(self.model) { item in
                NavigationLink (destination: PassportDetails(passportTitle: item.passportTitle,venues: item.venues,venueProd: []) ) {
                HStack {
                    VStack(alignment: .leading) {
                        Text(item.passport[0].passportTitle)
                            .fontWeight(.semibold)
                            .foregroundColor(Color.white)
                        Text(item.passport[0].passportDates)
                            .foregroundColor(Color.white)
                    }.frame(width: 400,height: 120)
                        .background(Color("wPurple"))
                        .cornerRadius(6)
                }
              }.padding(.horizontal) 
            }
        }
    }
}

PassportDetails.swift

struct PassportDetails: View {

var passportTitle: String
var venues: [Venue]
var venueProd: [venueItem]

var body: some View {

    List {
        ForEach(self.venues) { gc in
            Section(header: Text(gc.title)) {
                ForEach(gc.venueItems,id: \.title) { gi in
                    GeometryReader { geometry in
                        VStack(alignment: .leading) {
                            HStack {
                                Text(gi.title)
                                    .frame(width: geometry.size.width / 1.5,alignment: .leading)
                                    .fixedSize(horizontal: false,vertical: true)
                                    .padding(.top,10)
                                Spacer()
                                Text("$\(gi.productPrice,specifier: "%.2f")")
                                    .multilineTextAlignment(.trailing)

                            }.padding(.top,8)
                            HStack {
                                Text(gi.productDescription)
                                    .font(.footnote)
                                    .foregroundColor(Color.gray)
                                    .frame(width: geometry.size.width / 1.5,alignment: .leading)
                                .fixedSize(horizontal: false,vertical: true)
                                    .padding(.bottom,8)
                                Spacer()
                            }.padding(.bottom,8)
                        }
                    }.padding(.vertical)
                }
            }
        }
    }.listStyle(GroupedListStyle())
        .navigationBarTitle(Text(passportTitle),displayMode: .inline)
}
}

因此很明显“ Text（item.passport [0] .passportTitle）”将显示数组中的第一项，但是我想在顶部数组中显示所有passportTitles和passportDates并将信息传递给使用NavigationLink的详细信息视图。
