Hey all — I’ve been building out my first set of Game Center Achievements for a game I’m working on, and I’ve run into something odd with the image quality. The specs say to upload icons at 512x512 or 1024x1024@2x. I’ve been uploading 1024x1024 PNGs (without explicitly naming them “@2x” since there’s only one upload slot), assuming that Game Center would just handle the scaling automatically — kind of like how a lot of things are getting more streamlined across platforms lately. But in testing, the icons are showing up a bit blurry, especially in the Game Center interface. It’s not horrible, but it’s definitely softer than I expected — more like low-res than Retina. All my test devices (outside the Simulator) are running iOS 26, so I’m also wondering if this might be a beta-related display bug? Has anyone else run into this? Curious if I’m missing a best practice here, or if I really do need to ensure I’m uploading it with the @2x suffix, or maybe something else entirely? Thanks!

Been messing with this for a while... And cannot figure things out... Have a basic router implemented... import Foundation import SwiftUI enum Route: Hashable { case profile(userID: String) case settings case someList case detail(id: String) } @Observable class Router { var path = NavigationPath() private var destinations: [Route] = [] var currentDestination: Route? { destinations.last } var navigationHistory: [Route] { destinations } func navigate(to destination: Route) { destinations.append(destination) path.append(destination) } } And have gotten this to work with very basic views as below... import SwiftUI struct ContentView: View { @State private var router = Router() var body: some View { NavigationStack(path: $router.path) { VStack { Button("Go to Profile") { router.navigate(to: .profile(userID: "user123")) } Button("Go to Settings") { router.navigate(to: .settings) } Button("Go to Listings") { router.navigate(to: .someList) } .navigationDestination(for: Route.self) { destination in destinationView(for: destination) } } } .environment(router) } @ViewBuilder private func destinationView(for destination: Route) -> some View { switch destination { case .profile(let userID): ProfileView(userID: userID) case .settings: SettingsView() case .someList: SomeListofItemsView() case .detail(id: let id): ItemDetailView(id: id) } } } #Preview { ContentView() } I then have other views named ProfileView, SettingsView, SomeListofItemsView, and ItemDetailView.... Navigation works AWESOME from ContentView. Expanding this to SomeListofItemsView works as well... Allowing navigation to ItemDetailView, with one problem... I cannot figure out how to inject the Canvas with a router instance from the environment, so it will preview properly... (No idea if I said this correctly, but hopefully you know what I mean) import SwiftUI struct SomeListofItemsView: View { @Environment(Router.self) private var router var body: some View { VStack { Text("Some List of Items View") Button("Go to Item Details") { router.navigate(to: .detail(id: "Test Item from List")) } } } } //#Preview { // SomeListofItemsView() //} As you can see, the Preview is commented out. I know I need some sort of ".environment" added somewhere, but am hitting a wall on figuring out exactly how to do this. Everything works great starting from contentview (with the canvas)... previewing every screen you navigate to and such, but you cannot preview the List view directly. I am using this in a few other programs, but just getting frustrated not having the Canvas available to me to fine tune things... Especially when using navigation on almost all views... Any help would be appreciated.

how to save the state of my APP when I open another APP so that It can restore when I re-open it? my app will use over 10mb memory so if I open another APP(my app will go background) it will closed at all. when I re-open it it will restart. but I do not want it I want if I open Page A and then it go background and when I re-open it it still is Page A and do not restart.

I’m not seeing Liquid Glass on any standard components. A month ago around July 17th I ran our app and saw Liquid Glass on our tab view and various standard components. Those components have not been changed and yet I’m no longer seeing Liquid Glass in our app at all. Components that were previously liquid glass but now are not include TabView and back navigation buttons. I set the UIDesignRequiresCompatibility key explicitly to false but no luck. I was seeing this in Beta 7 and Beta 8 on a real device and on a sim.

Yesterday on Explore the biggest updates from WWDC Curt Clifton shared .background(.tint, in: .rect(corner: .containerConcentric)). XCode26 beta 3 don‘t recognize it. how when we can use it??

I want to be able to write a cross-platform screensaver that works on both Windows and macOS using the Pygame 2D graphics library in Python. On Windows, this is super easy - you just write your program with three possible command line arguments: /p for preview mode, /c for the configuration dialog mode, and /s for the actual full-screen screensaver mode. Then you just use pyinstaller to build an .exe file and rename the extension to .scr, and you're good to go. However, it seems that making a screensaver on macOS is a pretty convoluted process, and there was stuff about specific Objective-C functions that you had to write, and I didn't really understand the documentation. Could you please tell me if there is any way to simply get my Python Pygame program to build as a proper .saver file? Thanks!

Someone smarter than me please tell me if this will work... I want to have an edit screen for a SwiftData class. Auto Save is on, but I want to be able to revert changes. I have read all about sending a copy in, sending an ID and creating a new context without autosave, etc. What about simply creating a second set of ephemeral values in the actual original model. initialize them with the actual fields. Edit them and if you save changes, migrate that back to the permanent fields before returning. Don't have to manage a list of @State variables corresponding to every model field, and don't have to worry about a second model context. Anyone have any idea of the memory / performance implications of doing it this way, and if it is even possible? Does this just make a not quite simple situation even more complicated? Haven't tried yet, just got inspiration from reading some medium content on attributes on my lunch break, and wondering if I am just silly for considering it.

I am trying to create a menu picker for two or three text items. Small miracles, but I have it basically working. Problem is it uses a set, and I want to pass arrays. I need to modify PickerView so the Bound Parameter is an [String] instead of Set. Have been fighting this for a while now... Hoping for insights. struct PickerView: View { @Binding var colorChoices: Set<String> let defaults = UserDefaults.standard var body: some View { let possibleColors = defaults.object(forKey: "ColorChoices") as? [String] ?? [String]() Menu { ForEach(possibleColors, id: \.self) { item in Button(action: { if colorChoices.contains(item) { colorChoices.remove(item) } else { colorChoices.insert(item) } }) { HStack { Text(item) Spacer() if colorChoices.contains(item) { Image(systemName: "checkmark") } } } } } label: { Label("Select Items", systemImage: "ellipsis.circle") } Text("Selected Colors: \(colorChoices, format: .list(type: .and))") } } #Preview("empty") { @Previewable @State var colorChoices: Set<String> = [] PickerView(colorChoices: $colorChoices) } #Preview("Prefilled") { @Previewable @State var colorChoices: Set<String> = ["Red","Blue"] PickerView(colorChoices: $colorChoices) } My Content View is suppose to set default values the first time it runs, if no values already exist... import SwiftUI struct ContentView: View { @State private var viewDidLoad: Bool = false var body: some View { HomeView() .onAppear { // The following code should execute once the first time contentview loads. If a user navigates back to it, it should not execute a second time. if viewDidLoad == false { viewDidLoad = true // load user defaults let defaults = UserDefaults.standard // set the default list of school colors, unless the user has already updated it prior let defaultColorChoices: [String] = ["Black","Gold","Blue","Red","Green","White"] let colorChoices = defaults.object(forKey: "ColorChoices") as? [String] ?? defaultColorChoices defaults.set(colorChoices, forKey: "ColorChoices") } } } } #Preview { ContentView() } PickLoader allows you to dynamically add or delete choices from the list... import SwiftUI struct PickLoader: View { @State private var newColor: String = "" var body: some View { Form { Section("Active Color Choices") { // we should have set a default color list in contentview, so empty string should not be possible. let defaults = UserDefaults.standard let colorChoices = defaults.object(forKey: "ColorChoices") as? [String] ?? [String]() List { ForEach(colorChoices, id: \.self) { color in Text(color) } .onDelete(perform: delete) HStack { TextField("Add a color", text: $newColor) Button("Add"){ defaults.set(colorChoices + [newColor], forKey: "ColorChoices") newColor = "" } } } } } .navigationTitle("Load Picker") Button("Reset Default Choices") { let defaults = UserDefaults.standard //UserDefaults.standard.removeObject(forKey: "ColorChoices") let colorChoices: [String] = ["Black","Gold","Blue","Red","Green","White"] defaults.set(colorChoices, forKey: "ColorChoices") } Button("Clear all choices") { let defaults = UserDefaults.standard defaults.removeObject(forKey: "ColorChoices") } } } func delete(at offsets: IndexSet) { let defaults = UserDefaults.standard var colorChoices = defaults.object(forKey: "ColorChoices") as? [String] ?? [String]() colorChoices.remove(atOffsets: offsets) defaults.set(colorChoices, forKey: "ColorChoices") } #Preview { PickLoader() } And finally HomeView is where I am testing from - to see if binding works properly... import SwiftUI struct HomeView: View { //@State private var selection: Set<String> = [] //@State private var selection: Set<String> = ["Blue"] @State private var selection: Set<String> = ["Blue", "Red"] var body: some View { NavigationStack { List { Section("Edit Picker") { NavigationLink("Load Picker") { PickLoader() } } Section("Test Picker") { PickerView(colorChoices: $selection) } Section("Current Results") { Text("Current Selection: \(selection, format: .list(type: .and))") } } .navigationBarTitle("Hello, World!") } } } #Preview { HomeView() } If anyone uses this code, there are still issues - buttons on Loader don't update the list on the screen for one, and also dealing with deleting choices that are in use - how does picker deal with them? Probably simply add to the list automatically and move on. If anyone has insights on any of this also, great! but first I just need to understand how to accept an array instead of a set in pickerView. I have tried using a computed value with a get and set, but I can't seem to get it right. Thanks for any assistance! Cheers!

Hello, My app was rejected because of App Review Guideline 4.3 – Design Spam. I developed Dynasty of Sic Bo, an exciting game that combines elements of roulette and dice rolling. Players can bet on different dice combinations, testing their luck and strategy to win virtual riches. The game is designed to be simple and enjoyable for beginners while still engaging for experienced players. I’ve tried multiple times to understand the exact reasons for this rejection, but all my efforts have been ignored by App Review. None of the changes I implemented resolved the issue, and I still don’t know what specifically needs to be addressed. The app’s concept, gameplay, and design are entirely original, and I haven’t copied or reused content from other apps. While the game shares a general theme of dice-based gambling, I worked hard to create a unique experience with polished visuals, engaging mechanics, and a dynamic atmosphere. I don’t understand how to proceed or demonstrate the originality of my app, as I can’t identify any apps that are identical to mine. I would really appreciate any advice or insights on how to resolve this issue. Kind regards, Nick Bohdan Malashina

I've been experimenting with Liquid Glass quite a bit and watched all the WWDC videos. I'm trying to create a glassy segmented picker, like the one used in Camera: however, it seems that no matter what I do there's no way to recreate a truly clear (passthrough) bubble that just warps the light underneath around the edges. Both Glass.regular and Glass.clear seem to add a blur that can not be evaded, which is counter to what clear ought to mean. Here are my results: I've used SwiftUI for my experiment but I went through the UIKit APIs and there doesn't seem to be anything that suggests full transparency. Here is my test SwiftUI code: struct GlassPicker: View { @State private var selected: Int? var body: some View { ScrollView([.horizontal], showsIndicators: false) { HStack(spacing: 0) { ForEach(0..<20) { i in Text("Row \(i)") .id(i) .padding() } } .scrollTargetLayout() } .contentMargins(.horizontal, 161) .scrollTargetBehavior(.viewAligned) .scrollPosition(id: $selected, anchor: .center) .background(.foreground.opacity(0.2)) .clipShape(.capsule) .overlay { DefaultGlassEffectShape() .fill(.clear) // Removes a semi-transparent foreground fill .frame(width: 110, height: 50) .glassEffect(.clear) } } } Is there any way to achieve the above result or does Apple not trust us devs with more granular control over these liquid glass elements?

Hi all. I have tried using UIDesignRequiresCompatibility YES & NO for an application. Running on iOS 26 BETA 5 makes no difference to the UI. Running on Simulator MacOSS 26 BETA 5 makes no difference to the UI. Anyone had luck with this info plist setting?

Hello everyone. I'm building a simple Form in a Multiplatform App with SwiftUI. Originally I had something like this. import SwiftUI struct OnboardingForm: View { @State var firstName: String = "" @State var lastName: String = "" @State var email: String = "" @State var job: String = "" @State var role: String = "" var body: some View { Form { TextField("First Name", text: $firstName, prompt: Text("Required")) TextField("Last Name", text: $lastName, prompt: Text("Required")) TextField("Email", text: $email, prompt: Text("Required")) TextField("Job", text: $job, prompt: Text("Required")) TextField("Role", text: $role, prompt: Text("Required")) } } } #Preview { OnboardingForm() } In macOS it looks ok but then in iOS it looks like this: and it's impossible to know what each field is for if all the prompts are the same. I tried adding LabeledContent around each text field and that solves it for iOS but then on macOS it looks like this: The labels are shown twice and the columns are out of alignment. I think I could get around it by doing something like this: #if os(iOS) LabeledContent { TextField("First Name", text: $firstName, prompt: Text("Required")) } label: { Text("First Name") } #else TextField("First Name", text: $firstName, prompt: Text("Required")) #endif but it seems to me like reinventing the wheel. Is there a "correct" way to declare TextFields with labels that works for both iOS and macOS?

Dear Apple Developer Relations Team, We are currently reviewing the documentation for the UIDesignRequiresCompatibility Info.plist key. In the documentation, there is a warning that states: "Temporarily use this key while reviewing and refining your app’s UI for the design in the latest SDKs." However, in the adoption guide for Liquid Glass: Adopting Liquid Glass, we did not see any explicit requirement to force adoption of the Liquid Glass design. We have the Gojek app, which currently uses the UIDesignRequiresCompatibility key. To ensure long-term stability, we would like clarification on the following points: Future Support of the Key: Is it safe to continue using the UIDesignRequiresCompatibility key? Can you confirm whether this key will remain supported or if there are plans for it to be deprecated/removed in future iOS versions? Liquid Glass Adoption: Our app’s design guidelines do not align with the Liquid Glass style. Can you confirm that adoption of Liquid Glass is not mandatory, and that apps can continue to use their existing custom design guidelines without any restrictions? Compatibility with iOS 26: Are there any required changes we need to make to our existing views to ensure that the UI will continue to render as it does today on iOS 26 and beyond? We want to make sure we provide the best user experience while remaining compliant with Apple’s guidelines. Your clarification would help us plan our design and development roadmap accordingly. Thank you for your support and guidance.

The most recent update included coloured icons for grouping of emails anybody previously needing to group emails we’re able to achieve this alphabetically by simply searching for what you were looking for. These icons clutter the page with totally unnecessary screen pollution. if you want to persist with this folly can you please provide a classic display option for those of us who have happily survived using email for 30 years without this fluff.

I have an iPhone 15 pro with IOS 18.1 beta 5 and I don’t see in my settings Apple Intelligence & Siri. please help

The new "elevated" tab bar in iPadOS 18 covers the Navigation-/Toolbar of views within. A very simple example: import SwiftUI @main struct SampleApp: App { @State var selection: Int? var body: some Scene { WindowGroup { TabView { NavigationSplitView { List(0..<10, selection: $selection) { item in Text("Item \(item)") .tag(item) } } detail: { if let selection { Text("Detail for \(selection)") .navigationTitle("Item \(selection)") .navigationBarTitleDisplayMode(.inline) } else { Text("No selection") } }.tabItem { Label("Items", systemImage: "list.bullet") } Text("Tab 2") .tabItem { Label("Tab 2", systemImage: "list.bullet") } Text("Tab 3") .tabItem { Label("Another Tab", systemImage: "list.bullet") } } } } } I've tried using .safeAreaInset/.safeAreaPadding for the detail views, but they don't affect the NavigationBar, only the content within. Is there a way to move the NavigationBar down, so its items stay visible?

I already have an opinion ( I should never release to a platform without testing on a physical platform device ) on this but wanted to learn from experience and expertise and see if there were any viable options. My hybrid casual puzzle game is released on the App Store for iOS. (Whew!) Apparently it is compatible to both Mac OS and VisionOS I would love to make it available everywhere however, I am not sure it is best to do so without testing on these physical devices. Which could also mean making the design adjustments for those devices, having test devices ready etc. and I would have to update my Laptop to silicon. Has anyone tried this without testing on physical devices? What are your thoughts/best suggestions? Thanks in advance!

Hi, I have created a line graph using LineMark in Charts, which by default includes grid lines and axes lines. My requirement is to remove the grid lines but retain the axes lines and the values. I have tried the following code: .chartXAxis { AxisMarks(preset: .extended, values: .stride(by: 2), stroke: StrokeStyle(lineWidth: 0)) } This is removing grid lines as well as axes lines. How to retain axes lines while removing grid lines ?

How to create a beautiful fire animation using Swift? Which API is better to use?

Hi, I am trying to use a flag image inside a picker like this: Picker("Title: ", selection: $selection){ ForEach(datas, id: \.self){ data in HStack{ Text(data.name) if condition { Image(systemName: "globe") }else { Image(img) } } .tag(data.name) .padding() } } All images are loading successfully but only system images are resized correctly. Images loaded from Assets are appearing in their default size. I have tried to size the images with frames, etc but with no luck. Any idea, help will be much appreciated. Thanks in advance!
