When i have TextField inside ScrollView and tap on it the keyboard is shown as expected. But it seems that the TextField is moved up just enough to show the input area but i want to be moved enough so that is visible in its whole. Otherwise it looks cropped. I couldn't find a way to change this behaviour. struct ContentView: View {   @State var text:String = ""   var body: some View {     ScrollView {       VStack(spacing: 10) {         ForEach(1...12, id: \.self) {           Text("\($0)…")             .frame(height:50)         }         TextField("Label..", text: self.$text)           .padding(10)           .background(.white)           .cornerRadius(10)           .overlay(             RoundedRectangle(cornerRadius: 10)               .stroke(.blue, lineWidth: 1)           )       }       .padding()       .background(.red)     }   }     }

Are there good examples of integrating SwiftUI, Coredata and Cloudkit working nicely together?

I have a simple SwiftUI application with CoreData and two views. One view displays all "Place" objects. You can create new places and you can show the details for the place. Inside the second view you can add "PlaceItem"s to a place. The problem is that, once a new "PlaceItem" is added to the viewContext, the @NSFetchRequest seems to forget about its additional predicates, which I set in onAppear. Then every place item is shown inside the details view. Once I update the predicate manually (the refresh button), only the items from the selected place are visible again. Any idea how this can be fixed? Here's the code for my two views: struct PlaceView: View { @FetchRequest(sortDescriptors: []) private var places: FetchedResults<Place> @Environment(\.managedObjectContext) private var viewContext var body: some View { NavigationView { List(places) { place in NavigationLink { PlaceItemsView(place: place) } label: { Text(place.name ?? "") } } } .toolbar { ToolbarItem(placement: .primaryAction) { Button { let place = Place(context: viewContext) place.name = NSUUID().uuidString try! viewContext.save() } label: { Label("Add", systemImage: "plus") } } } .navigationTitle("Places") } } struct PlaceItemsView: View { @ObservedObject var place: Place @FetchRequest(sortDescriptors: []) private var items: FetchedResults<PlaceItem> @Environment(\.managedObjectContext) private var viewContext func updatePredicate() { items.nsPredicate = NSPredicate(format: "place == %@", place) } var body: some View { NavigationView { List(items) { item in Text(item.name ?? ""); } } .onAppear(perform: updatePredicate) .toolbar { ToolbarItem(placement: .primaryAction) { Button { let item = PlaceItem(context: viewContext) item.place = place item.name = NSUUID().uuidString try! viewContext.save() } label: { Label("Add", systemImage: "plus") } } ToolbarItem(placement: .navigationBarLeading) { Button(action: updatePredicate) { Label("Refresh", systemImage: "arrow.clockwise") } } } .navigationTitle(place.name ?? "") } } struct ContentView: View { @Environment(\.managedObjectContext) private var viewContext var body: some View { NavigationView { PlaceView() } } } Thanks!

Hi, I'm embedding the QLPreviewController in a UIViewControllerRepresentable. When I view .usdz models I don't see the AR/Object selector at the top, nor the sharing button. I have tried presenting modally with a .sheet modifier and had the same result. What do I need to do to get the controls? Thanks, code attached. Code Spiff

Hi, I'm trying to make a weather menu bar app, and I want to have it so that the icon of the app in the menu changes with the actual weather, but the icon isn't showing up. There is still a space in the menu bar where I can click and open the app, it's just that the icon has disappeared. Any ideas to fix it?

Hi, In a Mac Catalyst app, I need to allow the user insert a passcode using a UITextField. The field is used to insert a one time passcode and I want to keep the content hidden. For this reason I set the isSecureTextEntry property to true. passcodeTextField.isSecureTextEntry = true By doing this, a button to allow the user to pick a password from the keychain is displayed: This option in my case should not appear because the password is a one time password that change every time. For that reason I set the textContentType to oneTimeCode. passcodeTextField.textContentType = .oneTimeCode This actually removes the password button, but introduce something weird. If the user type something and then delete everything, a big empty box appear under the field: I have no idea what this box is and why it appears. Does anyone know why it appears and how I can remove it? Thank you

Hi, I've implemented the FamilyActivityPicker and I also noticed that it is the same picker that we get when we go to Setttings > Screen Time > App Limits > Add Limit. When you tap on a given row, it will present all apps that are in that category. If you press the check mark on Category then on the Category row will be updated by showing the checkmark as selected and a "All" text to the right side, and on the app rows from that category the check marks will also be marked as selected. This behavior is not consistent when I implement the FamilyActivityPicker. If I go through the same process the app rows won't be shown as selected. Any suggestions on how to make this work? I'm attaching screen shots to illustrate my point. Settings App My FamilyActivityPicker Implementation

I have a NSRulerView with a vertical orientation. It works fine from macOS 10.13 to 11.x. In macOS Monterey (12.2.1 here), the ruler view is not receiving drawHashMarksAndLabelsInRect: messages when the associated NSTextView is scrolled vertically. When the parent NSScrollView is resized, the ruler view is correctly refreshed on all macOS versions. [Q] Is it a known bug in macOS Monterey?

Hi dear , I am a beginner developer I have an application idea , and I think its great idea 😎 I think the application needs to use Device activity frame work , and UIScreen class , even if the app is in background or terminated , the problem is I don't know how to use these classes and frameworks 🤷🏻‍♂️ the questions are : can I detect UITouch event on UIScreen object even if the app is in background or terminated How to get the current activity name of the device

Is there a way to optimize a List in SwiftUI? There is a problem with selection not working properly when the List has many rows. If you scroll to multi-select and up, some rows in the middle are not selected. I have an issue where selecting an unselected row deselects nearby rows. Is there any way for selection to work reliably even for a List of many rows? I would like to find a solution that is stable even when multiple lines are selected, like mail and note, which are the default apps in ios. ps. I am using CoreData. @State var selectedItem = Set<MyEntity>() List(selection: $selectItem){   ForEach(items, id: \.self){ item in     ContactsRow(contactsData: item)   } } .environment(\.editMode, $editMode)

Overview I am bit confused regarding drag and drop on SwiftUI I think there are 2 approaches but I am stuck with both approaches WWDC22 When using the new draggable, dropDestination, Transferable API, only single items are draggable. Multiple items in a list are not draggable. I have filed a feedback FB10128110 WWDC21 I have faced a couple of issues for drag and drop introduced in WWDC21 (onDrag, onDrop, itemIdentifier), the Feedback ids are FB9854301, FB9854569, FB9855245, FB9855532, FB9855567, FB9855575. It contains sample projects, would really appreciate if someone could have a look it. Note: All feedbacks include a sample project with detail steps and some even have screenshots and videos Questions: If my approach is wrong or if I am missing something? Unfortunately I didn't manage to get a SwiftUI lab session (got cancelled), so please help me with these issues.

After updating to NavigationStack with nested navigation links (with navigation links in a navigation destination), I see a lot of warnings in Xcode 14 beta: Update NavigationAuthority bound path tried to update multiple times per frame. Update NavigationAuthority possible destinations tried to update multiple times per frame. The app often freezes when navigated with a NavigationLink. Do others see these problems?

In TextKit 1, I can override drawBackground(forGlyphRange:at:) in NSLayoutManager to do custom background drawing. However, I'm not too sure what the designated way of doing background drawing is in TextKit 2. One thing I've tried is to do custom drawing in my own CALayer that's used in the configureRenderingSurface delegate callback, but I'm unsure if we are suppose to use this API and steal the textViewportLayoutController.delegate away from _UITextLayoutcanvasView?

struct ContentView: View {   @State var isPresented = false   var body: some View {     Button {       isPresented.toggle()     } label: {       Text("Button")     }     .sheet(isPresented: $isPresented) {       SubView()     }   } } struct SubView: View {   @State var text = ""   var body: some View {     NavigationStack {       TextEditor(text: $text)         .toolbar {           ToolbarItemGroup(placement: .bottomBar) {             Button("Click") {             }           }           ToolbarItemGroup(placement: .keyboard) {             Button("Click") {             }           }         }     }   } }

The Problem In our brand new SwiftUI project (Multiplatform app for iPhone, iPad and Mac) we are using a ScrollView with both .horizontal and .vertical axes enabled. In the end it all looks like a spreadsheet. Inside of ScrollView we are using LazyVStack with pinnedViews: [.sectionHeaders, .sectionFooters]. All Footer, Header and the content cells are wrapped into a LazyHStack each. The lazy stacks are needed due to performance reasones when rows and columns are growing. And this exactly seems to be the problem. ScrollView produces a real layout mess when scrolling in both axes at the same time. Tested Remedies I tried several workarounds with no success. We built our own lazy loading horizontal stack view which shows only the cells whose indexes are in the visible frame of the scrollview, and which sets dynamic calculated leading and trailing padding. I tried the Introspect for SwiftUI packacke to set usesPredominantAxisScrolling for macOS and isDirectionalLockEnabled for iOS. None of this works as expected. I also tried a workaround to manually lock one axis when the other one is scrolling. This works fine on iOS but it doesn't on macOS due to extreme poor performance (I think it's caused by the missing NSScrollViewDelegate and scroll events are being propagated via NotificationCenter). Example Screen Recordings To give you a better idea of what I mean, I have screenshots for both iOS and macOS. Example Code And this is the sample code used for the screenshots. So you can just create a new Multiplatform project and paste the code below in the ContentView.swift file. That's all. import SwiftUI let numberOfColums: Int = 150 let numberOfRows: Int = 350 struct ContentView: View { var items: [[Item]] = { var items: [[Item]] = [[]] for rowIndex in 0..<numberOfRows { var row: [Item] = [] for columnIndex in 0..<numberOfColums { row.append(Item(column: columnIndex, row: rowIndex)) } items.append(row) } return items }() var body: some View { Group { ScrollView([.horizontal, .vertical]) { LazyVStack(alignment: .leading, spacing: 1, pinnedViews: [.sectionHeaders, .sectionFooters]) { Section(header: Header()) { ForEach(0..<items.count, id: \.self) { rowIndex in let row = items[rowIndex] LazyHStack(spacing: 1) { ForEach(0..<row.count, id: \.self) { columnIndex in Text("\(columnIndex):\(rowIndex)") .frame(width: 100) .padding() .background(Color.gray.opacity(0.2)) } } } } } } .edgesIgnoringSafeArea([.top]) } .padding(.top, 1) } } struct Header: View { var body: some View { LazyHStack(spacing: 1) { ForEach(0..<numberOfColums, id: \.self) { idx in Text("Col \(idx)") .frame(width: 100) .padding() .background(Color.gray) } Spacer() } } } struct Item: Hashable { let id: String = UUID().uuidString var column: Int var row: Int } Can You Help? Okay, long story short... Does anybody knows a real working solution for this issue? Is it a known SwiftUI ScrollView bug? If there were a way to lock one scrolling direction while the other is scrolled, then I could deal with that. But at the moment, unfortunately, it is not usable for us. So any solution is highly appreciated! Ideally an Apple engineer can help. 😃 NOTE: Unfortunately Apple does not allow URLs to anywhere. I also have two screen recordings for both iOS and macOS. So, if you would like to watch them, please contact me.

We have been having problems with our app clip not working when sharing through iMessage. The app and app clip are published and work correctly when scanning a QR code that points to the URL: https://www.coderus.com/locations?loc=1 however if this same URL is shared through the iMessage app, a link to the website displays and not the app clip card. We have confirmed that: AASA file is available and has the type application/json Both devices are above iOS 14 Both devices are in each other's contacts The website has the meta tag for the smart app clip banner The website has a meta tag for the og:image Launch experiences have been configured on AppStoreConnect - as said before, the QR codes work correctly The link leads to a 404 page, I wasn't sure if there needs to be an actual page that the link points to as app clips seem to work fine without when scanning the QR code through the camera app.

I am currently running Xcode Version 14.0 beta (14A5228q) creating a Multiplatform app. I wanted to include a LaunchScreen so added a Launch Screen Storyboard to my project. To the the app to see it I went under Target for my app, General, and under App Icons and Launch Screen I set the Launch Screen File to my storyboard. This works perfectly when I run the app on iOS; however, when I run it on macOS I get an error:Launch Screen.storyboard error build: iOS storyboards do not support target device type "Mac". I see there's no way to differentiate between macOS and iOS with the file and there's only one target. Does anyone know a way to make the storyboard only launch when running the iOS app (and iPadOS) and not be seen when running macOS? Thanks

Facing issue of NSUserDefaults data got cleared on update new version from app store. so all data of user got cleared and user have to login again. I was having app in store with version 1.1.3 and then we have uploaded new version to store with version 1.1.4 but when user download app from store their data was cleared from UserDefaults.so this is big issue in update. need to help. is that apple updated any process on update. Question How Apple change version build in device when we update app from app store. is it uninstall old build and install new build ? Or it is install new version on old version ? Should UserDefaults.standard will delete on update ? Updating Provisioning profile from manual to automatically cause issue on UserDefaults.standard Like UserDefaults got cleared and uuid will change ? Do we have anythings that we can identify specific user as uniq user ? What is better solution to store login data into SQLite store or in UserDefaults as model ? Will appreciate for your help. this is very big issue and login again on update will make app user more effect

Hello 👋🏽 I am a new iOS developer and I am having a hard time understanding the behavior of the new UIPasteControl to avoid showing the system prompt. Does anyone has any example code I could look at to understand the behavior. Idk how to set the target of the button to the general pasteboard. also I am using objective-c . thanks cristian

Hi there, I'm currently using UIHostingController to display swift charts in uikit. The problem im facing is that the UIHostingController isn't outputting the intended theme. When the simulator/phone is on dark mode the view is still in light mode. Iv'e tried to force the view to use dark mode with: .environment(\.colorScheme, .dark) But it doesn't seem to help. Here's how I implement the UIHostingController to my view: let controller = UIHostingController(rootView: StatVC()) controller.view.translatesAutoresizingMaksIntoConstraints = false addChild(controller) controller.didMove(toParent: self) view.addSubview(controller.view) where StatVC() is the swiftui view which contains the swift chart.
