My listView is simplestruct ListView: View { var body: some View { NavigationView { List(myList) { element in NavigationLink(destination: NextView()) { Text(element.name) } } } } }Thought I could set a background Image for the whole View with.background(Image("ImageName"))modifier. But the lists background is still white. I don't want to set an image for each row only once for the whole view.Can anyone help?

I'm new to SwiftUI and tried my first project on it.So I want to make an iOS app which is showing some data from Firestore in a list. The list is empty because MonsterT is empty. How can I call the init of Class MonsterC?In my SceneDelegate I added following line in func scene and added this variable:class SceneDelegate: UIResponder, UIWindowSceneDelegate { var window: UIWindow? var monsterT = MonsterC() func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionIf using a storyboard, the `window` property will automatically be initialized and attached to the scene. // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead). // Create the SwiftUI view that provides the window contents. let contentView = ContentView().environmentObject(monsterT) // Use a UIHostingController as window root view controller. if let windowScene = scene as? UIWindowScene { let window = UIWindow(windowScene: windowScene) window.rootViewController = UIHostingController(rootView: contentView) self.window = window window.makeKeyAndVisible() } }...My Listimport SwiftUI struct ContentView: View { @EnvironmentObject var monsterT: MonsterC var body: some View { List(monsterT.monsters, id: \.self) { monster in Text(monster.name) } } }My MonsterC Class with MonsterObjimport SwiftUI import FirebaseFirestore import FirebaseFirestoreSwift struct MonsterObj: Identifiable, Equatable, Hashable { var id = UUID() var name: String var element: String var immune: String var size: String var twoStarWeakness: String var threeStarWeakness: String #if DEBUG static let exampleMonster = MonsterObj(id: UUID(), name: "Test Monster", element: "Test Element", immun: "Test immune", groesse: "Test size", twoStarWeakness: "Test 2 Weakness", threeStarWeakness: "Test3 Weakness") #endif } class MonsterC: ObservableObject { var db = Firestore.firestore() @Published var monsters = [MonsterObj]() init() { var monsterCount: [String] = [""] monsterCount.remove(at: 0) db.collection("Monster").getDocuments() { (querySnapshot, err) in if let err = err { print(err) } else { for document in querySnapshot!.documents { monsterCount.append(document.documentID) } } } for monsterName in monsterCount { print(monsterName) db.collection("Monster").document(monsterName).getDocument { (document, error) in if let document = document, document.exists { let elementGetter = document.get("element") as! String let immuneGetter = document.get("immune") as! String let sizeGetter = document.get("size") as! String let twoStarWeaknessGetter = document.get("2 Star Weakness") as! String let threeStarWeaknessGetter = document.get("3 Star Weakness")as! String self.monsters.append(MonsterObj.init(name: monsterName, element: elementGetter, immune: immuneGetter, size: sizeGetter, twoStarWeakness: twoStarWeaknessGetter, threeStarWeakness: threeStarWeaknessGetter)) } } } }What am I doing wrong or missing?Thanks in advance 🙂

I'm new to swiftUI.There must be a way to make this better.For example if I add an Item (for example: "name5") to names I have to add a new HStack Block in my Code.How can I do this more efficient?import SwiftUI struct name: View { let names = ["name1", "name2", "name3", "name4"] var body: some View { List { VStack { HStack { Image(names[0]) Text(names[0]) } HStack { Image(names[1]) Text(names[1]) } HStack { Image(names[2]) Text(names[2]) } HStack { Image(names[3]) Text(names[3]) } } } } } struct monsterList_Previews: PreviewProvider { static var previews: some View { name() } }Maybe something like this.Pseudocode: foreach i in names.count: HStack { Image(names[i]) Text(names[i]) }if I add an Item to names it should automatically increase the list by the new element.thanks in advance

Hey,I'm a beginner hobby dev who tried cloud storage for first time using SwiftUI.I wanted to make a simple app which only needs to retrieve some values of a Database.I'm using Firebase RealTime Database.My Database structure looks like this:monsterhunter-e8167 Velkhana HP: 12000element: IceRath HP: 8000element: FireMy Code looks like this:import SwiftUI import FirebaseDatabase struct ContentView: View { var ref: DatabaseReference = Database.database().reference() var body: some View { Button(action: { self.ref.child("monsterhunter-e8167").child("Velkhana") .observeSingleEvent(of: .value, with: { (snapshot) in let value = snapshot.value as? NSDictionary let hp = value?["HP"] as? Int ?? 0 print(hp) // ... }) { (error) in print(error.localizedDescription) } }) { Text("print") } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } }However it is printing out0the expected output should be:12000I figured out "value" is nil but I don't know why."childpath" should be correctCan anyone tell me what I'm doing wrong?

Hello,I'm learning CoreData but my Tutorial is about one year old so not everything is up to date and I don't understand where the problem is. My Project includes an TableViewController with an bar button item. Here is the codeCoreDataResource.swift:import UIKit import CoreData class CoreDataResource { // /Document var documentDir : URL { let allUrls = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask) return allUrls[0] } let appDelegate = UIApplication.shared.delegate as! AppDelegate private var managedObjectModel: NSManagedObjectModel { guard let url = Bundle.main.url(forResource: "Listen", withExtension: "momd") else { fatalError("fix me: not found?") } guard let model = NSManagedObjectModel(contentsOf: url) else { fatalError("error in the model?") } return model } private var storeCoordinator: NSPersistentStoreCoordinator { let coordinator = NSPersistentStoreCoordinator(managedObjectModel: self.managedObjectModel) let url = self.documentDir.appendingPathComponent("Listen.sqlite") do { try coordinator.addPersistentStore(ofType: NSSQLiteStoreType, configurationName: nil, at: url, options: nil) } catch { print(error) } return coordinator } var managedContext: NSManagedObjectContext { let context = NSManagedObjectContext(concurrencyType: .mainQueueConcurrencyType) context.persistentStoreCoordinator = self.storeCoordinator return context } func saveContext() { if managedContext.hasChanges { do { try managedContext.save() } catch { print(error) } } } func loadLists() -> [Liste] { let request: NSFetchRequest = Liste.fetchRequest() var listen = [Liste]() do{ listen = try managedContext.fetch(request) } catch { print(error) } return listen } func newList(_ name: String) { let newList = NSEntityDescription.insertNewObject(forEntityName: "Liste", into: managedContext) as! Liste newList.name = name saveContext() } }ListTableViewController.swift:import UIKit class ListTableViewController: UITableViewController { let appDelegate = UIApplication.shared.delegate as! AppDelegate var listen = [Liste]() override func viewDidLoad() { super.viewDidLoad() reloadList() } private func reloadList() { listen = appDelegate.coreDataResource.loadLists() } @IBAction func addDummyData(_ sender: Any) { appDelegate.coreDataResource.newList("Test entry") appDelegate.coreDataResource.saveContext() reloadList() } // MARK: - Table view data source override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "listCell", for: indexPath) let liste = listen[indexPath.row] cell.textLabel?.text = liste.name return cell } override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { // #warning Incomplete implementation, return the number of rows return listen.count } }If I press in Simulator on the addDummyData button the following error occurs:CoreData: error: Mutating a managed object 0x6000026b25c0 <x-coredata:///Liste/t8A4529E8-BD3B-4157-B3AF-E8B011B6C46E2> (0x6000005b6300) after it has been removed from its context.I can't find the mistake. Please help me it's frustrating 😀
