Thank you, this code worked.In the future I will start a new post.
Post not yet marked as solved
I have two follow up questions. If I have to open a new post for these, just let me know.First, I have a problem with some text not being displayed completely (see legal.penalty in the LegalDetail.swift file) in the simulator. From Iphone 8s there is no problem, but on the Iphone 8 the texts are cut and end with [...]Is there any reason why?Second, I want to ad a searchbar on the LegalList view. I try to search on the legal name (the names are displayed in the list).I added in the LegalList.swift:@State privatevar searchTerm: String = ""and under List {SearchBar(text: $searchTerm)in a different file (SearchBar.swift) I have the following code:import Foundation
import SwiftUI
struct SearchBar: UIViewRepresentable {
@Binding var text: String
class Coordinator: NSObject, UISearchBarDelegate {
@Binding var text: String
init(text: Binding) {
_text = text
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
text = searchText
}
}
func makeCoordinator() -> SearchBar.Coordinator {
return Coordinator(text: $text)
}
func makeUIView(context: UIViewRepresentableContext) -> UISearchBar {
let searchBar = UISearchBar(frame: .zero)
searchBar.delegate = context.coordinator
return searchBar
}
func updateUIView(_ uiView: UISearchBar, context: UIViewRepresentableContext) {
uiView.text = text
}
}I suppose that I have to change this code:ForEach(userData.legals) { legal in
if !self.userData.showFavoritesOnly || legal.isFavorite {
NavigationLink(
destination: LegalDetail(legal: legal)
.environmentObject(self.userData)
) {
LegalRow(legal: legal)
but I can't figure out how.I already tried the following:ForEach(userData.legals) {self.search.isEmpty ? true :
$0.localizedCaseInsensitiveContains(self.search)}, id:\.self {Any help is appreciated 🙂

Thank you for the answers. It worked for now with the revised code from OOPer.To be complete, the code for legalData was in a different file:import Foundation
import CoreLocation
import UIKit
import SwiftUI
let legalData: [Legal] = load("legalData.json")
func load(_ filename: String) -> T {
let data: Data
guard let file = Bundle.main.url(forResource: filename, withExtension: nil)
else {
fatalError("Can't find \(filename) in main bundle")
}
do {
data = try Data(contentsOf: file)
} catch {
fatalError("Can't load \(filename) from main bundleà")
}
do {
let decoder = JSONDecoder()
return try decoder.decode(T.self, from : data)
} catch {
fatalError("Can't parse \(filename) as \(T.self):\n\(error)")
}
}

thanks for the answer, but it didn't do anything.I'll try to clarify my model (work in progress 🙂).Legal.swift file is structured as follows:struct Legal: Hashable, Codable, Identifiable {
var name: String
var place: String
var category: Category
var isFavorite: Bool
var penalty: String
enum Category: String, CaseIterable, Codable, Hashable {
case categoryone = "category One"
case categorytwo = "category Two"
case categorythree = "category Three"
}
}UserData.swift file is structured as follows:import Combine
import SwiftUI
final class UserData: ObservableObject {
@Published var showFavoritesOnly = false
@Published var legals = legalData
}A few examples from my legal.json file:[
{
"name": "infringement 1",
"category": "Category 1",
"place": "UK",
"id": 7004,
"isFavorite": false,
"penalty": "473 EUR",
},
{
"name": "infringement 2",
"category": "Category 2",
"place": "France",
"id": 1046,
"isFavorite": false,
"penalty": "116 EUR"
}
]Home.swift file = home view is structured as follows:import SwiftUI
struct Home: View {
@EnvironmentObject private var userData: UserData
var body: some View {
NavigationView {
List {
NavigationLink(destination: CategoryoneList()) {
Text("1. Category one")
}
NavigationLink(destination: CategorytwoList()) {
Text("2. Category two")
}
NavigationLink(destination: CategorythreeList()) {
Text("3. Category three")
}
NavigationLink(destination: LegalList()) {
Text("4. Overview").bold().underline()
}
}
.navigationBarTitle("View", displayMode: .inline)
}
}
}LegalList.swift file contains all the legal provisions (disregarding the categories)This is structured as follows:struct LegalList: View {
@EnvironmentObject private var userData: UserData
var body: some View {
List {
Toggle(isOn: $userData.showFavoritesOnly) {
Text("Show Favorites").bold().underline()
}
ForEach(userData.legals) { legal in
if !self.userData.showFavoritesOnly || legal.isFavorite {
NavigationLink(
destination: LegalDetail(legal: legal)
.environmentObject(self.userData)
) {
LegalRow(legal: legal)
}
}
}
}
.navigationBarTitle("4. Overview", displayMode: .inline)
}
}LegalDetail.swift file is structured as follows:struct LegalDetail: View {
@EnvironmentObject var userData: UserData
var legal: Legal
var legalIndex: Int {
userData.legals.firstIndex(where: { $0.id == legal.id })!
}
var body: some View {
List {
VStack {
HStack(alignment: .top) {
Text(legal.name).bold().underline()
}
.padding()
.foregroundColor(Color.green)
Spacer()
VStack(alignment: .leading) {
Text(legal.place)
Divider()
}
Text("Penalty").bold().underline()
.padding()
.foregroundColor(Color.orange)
VStack(alignment: .leading) {
Text(legal.penalty)
Divider()
}
}
}.navigationBarTitle(legal.name)
.navigationBarItems(trailing:
Button(action: {
self.userData.legals[self.legalIndex]
.isFavorite.toggle()
}) {
if self.userData.legals[self.legalIndex]
.isFavorite {
Image(systemName: "star.fill")
.foregroundColor(Color.yellow)
} else {
Image(systemName: "star")
.foregroundColor(Color.gray)
}
}.font(.system(size: 27))
)
}LegalRow.swift file is structured as follows:struct LegalRow: View {
var legal: Legal
var body: some View {
HStack {
Text(legal.name)
Spacer()
if legal.isFavorite {
Image(systemName: "star.fill")
.imageScale(.medium)
.foregroundColor(.yellow)
}
}
}
}The question now is how to make a seperate view for Category one, two and three, with the list of only the legal provisions of that category.Regarding the question of the allElements, this was a suggestion of Claude31.My apologies for the long post and again thanks in advance

In my "Data.swift" file:struct Legal: Hashable, Codable, Identifiable { var name: String var place: String var category: Category var isFavorite: Bool var penalty: String enum Category: String, CaseIterable, Codable, Hashable { case categoryone = "category One" case categorytwo = "category Two" case categorythree = "category Three" }}In my "legalData.json" file there a several legal provisions following this structure.I want to sort the legal provisions of categoryone in a separate view:Import SwiftUIstruct CategoryoneList: View { @published var legals = legalData var allElements: [Legal] = [] var body: some View { NavigationView { List { ForEach(...) { legal in if !self.userData.showFavoritesOnly || legal.isFavorite { NavigationLink(destination: LegalDetail(legal: legal) .environmentObject(self.userData) ) { LegalRow(legal: legal } } } }}I want to know what I have to type in (...) to have only the legal provisions in this view.Thanks in advance
