Swifui Realmdatabase Listview crashes - xcode

Question

Good evening,
I'm implementing a Realm Database with SwiftUI.
The Database is made of a table containing "Projects" and a table containing "Measures" (relation one-to-many).
The main view displays the project list and "Measureview" displays the measures related to the project selected.
When I select a project, the measures list is displayed and then impossible to go back, the app crashes (simulator and real device).
Xcode points AppDelegate file : Thread 1: EXC_BAD_ACCESS (code=2, address=0x7ffedfd5cfd8)
I know that 4/5 months ago, some developers experienced this issue but I suppose that currently Apple fix the problem.
Please find below the relevant code :
Realm part :
import Foundation
import RealmSwift
import Combine
class Project : Object, Identifiable {
#objc dynamic var ProjectName = "" // primary key
#objc dynamic var ProjectCategorie = ""
#objc dynamic var ProjectCommentaire = ""
let Measures = List<Measure>() // one to many
override static func primaryKey() -> String? {
return "ProjectName"
}
}
class Measure : Object, Identifiable {
// #objc dynamic var id_Measure = UUID().uuidString // primary key
#objc dynamic var MeasureName = ""
#objc dynamic var MeasureDetail = ""
#objc dynamic var MeasureResult = ""
override static func primaryKey() -> String? {
return "MeasureName"
}
}
func createProject (_ title:String,_ categorie:String, _ commentaire:String) {
let realm = try! Realm()
let proj = Project()
proj.ProjectName = title
proj.ProjectCategorie = categorie
proj.ProjectCommentaire = commentaire
try! realm.write {
realm.add(proj)
}
}
//****************************************************************
class BindableResults<Element>: ObservableObject where Element: RealmSwift.RealmCollectionValue {
let didChange = PassthroughSubject<Void, Never>()
let results: Results<Element>
private var token: NotificationToken!
init(results: Results<Element>) {
self.results = results
lateInit()
}
func lateInit() {
token = results.observe { _ in
self.didChange.send(())
}
}
deinit {
token.invalidate()
}
}
Contentview :
struct ContentView : View {
#ObservedObject var Proj = BindableResults(results: try! Realm().objects(Project.self))
var body: some View {
NavigationView{
List(Proj.results) { item in
NavigationLink(destination: MeasureView(Pro: item) ){
ContenRowUI(Proj :item)
}
}
}
.navigationBarTitle(Text("Project List"))
}
}
Measure view :
struct MeasureView: View {
var Pro = Project() //= Project()
var body: some View {
NavigationView {
List(Pro.Measures) { item in
Text("Detail: \(item.MeasureDetail)")
}
.navigationBarTitle(Text("Measure"))
}
}
}
Additional information, if I replace Measureview by a simple textview, the behaviour is very weird :
I select a Project, the application shows the textview and goes back automatically to the main list (project list)
If someone could help me, I would be grateful.
Thanks a lot for your support.
