Hi community, I have a question regarding MusicKit, is it necessary to follow a design guideline to integrate this framework into my App? Also, when no music is reproducing in MusicKit which placeholder we should show, do you provide the resource? Or can we create our own placeholder? Thanks for all, David.

Hello, My app was rejected because of App Review Guideline 4.3 – Design Spam. The response I received states: “We noticed your app shares similar features, interface design, and functionality with other apps available on the App Store. Apps that duplicate content or functionality from other apps without adding significant value or unique user experiences are considered spam and will not be approved for distribution.” I developed Plinking Platform Rise, a reaction and accuracy game where players control a platform to balance a ball while avoiding obstacles. The game becomes more challenging with each level, and a dark mode adds an exciting element by reducing visibility and requiring greater precision. I’ve tried multiple times to understand the exact reasons for this rejection and made several updates to address potential issues, but all my efforts have been ignored by App Review. None of the changes I implemented led to a resolution. This is the first app I’ve submitted to the App Store, and I developed it independently. I haven’t copied any design, functionality, or gameplay from existing apps. While my app uses Unity, which might result in some similarities, I’ve worked hard to create a unique experience with original gameplay, visuals, and mechanics. I can’t identify any apps that closely resemble mine, but the rejection suggests otherwise. I would appreciate any advice on how to resolve this issue and demonstrate the originality of my app. Kind regards, Ihor Koval

My app, Plinco, was rejected under App Review Guideline 4.3 – Design Spam, stating that it shares similarities with other apps available on the App Store. However, Plinco is a completely unique entertainment experience, designed with original assets, mechanics, and features. It allows users to customize various elements, including risk levels and configurations, ensuring a personalized and engaging experience. Special features like triple elements and the legendary golden mode introduce an extra layer of excitement and strategy. The app also offers high-quality visuals, immersive sound, and dynamic interactions, making each session feel fresh and unique. I conducted extensive research on the App Store and found no similar apps in the Entertainment category that match Plinco's concept and functionality. My app is built from scratch, without using pre-existing templates or duplicated content. Despite implementing multiple updates to address potential concerns, I have not received specific feedback clarifying the exact issue. I am fully committed to delivering a high-quality and original app and kindly request a more detailed explanation of the rejection, as well as a fair review of my submission. I appreciate your time and consideration.

In Apple's Maps app, an annotation is made up of a circle shape or rounded rectangles with a glyph-image. When selecting an annotation, the annotation animates into a balloon marker (see attached GIF). How does Apple Maps solve this - from custom annotation to balloon marker with spring animation? I switched my Maps implementation from SwiftUI to UIKit with a UIViewRepresentable to support annotation clustering - and it works beautifully. But how to subclass an MKAnnotationView (or MKMarkerAnnotationView <- the balloon) to enable selection and animation as in Apple Maps? MKMarkerAnnotationView only show balloon markers and I tried everything inside MKAnnotationView (CALayer, etc.)

I tried to create a Text View using attributedString. I want to set the line height using paragraphStyle and return the Text, but paragraphStyle is not being applied. Why is that? extension Text { init?(_ content: String, font: StyleType, color: Color = .ppBlack) { var attributedString = AttributedString(content) attributedString.font = Font.custom(font.fontWeight, fixedSize: font.fontSize) attributedString.foregroundColor = color let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.minimumLineHeight = 16 paragraphStyle.maximumLineHeight = 16 paragraphStyle.lineSpacing = 0 attributedString.mergeAttributes(.init([.paragraphStyle: paragraphStyle])) self = Text(attributedString) } }

I am developing an app that requires calling the iPhone's Face ID module to scan users' facial data. Where can I find Apple's design resources and guidelines for Face ID? The Face ID resources available in Figma are incomplete, and I need more support. For example, in the iPhone settings, the scenario: the UI interface for scanning the user's face to collect data, specifically the circular design in the "How to Set Up Face ID" screen.

We are trying to write an iOS app that supports regular and constrained widths using a TabView with .tabViewStyle(.sidebarAdaptable). On the surface this seems like a great way to write an app that supports all the different widths that your app may run in. Especially since Stage Manager and Apple Vision have made it easy for users to resize your apps window while it is running. We are facing many challenges though. I will give a brief one liner of each below, but to truly experience them you need to run the sample app, or watch the sample videos included. Issues Basic TabView Issues Double Navigation Bar: When tabs are collapsed into a "More" tab, there's an unwanted double navigation bar Selection Sync: Tab selection gets out of sync when switching between narrow/wide layouts through the "More" tab TabView Crash Fatal crash occurs when resizing window to narrow width while Tab 5 is selected Error: SwiftUI/SidebarAdaptableTabViewStyle_iOS.swift:482: Fatal error: Tried to update with invalid selection value Section Handling Issues Section Display Bug: Bottom tabs incorrectly show section names instead of tab names in narrow width Tab Selection Mismatch: Tab identifiers don't match selected tabs in narrow width mode Customization Issues Inconsistent "Edit" button behavior in More tab Unable to properly disable tab customization Sample app and video https://github.com/copia-wealth-studios/swiftui-tabview-sample

In macOS application, we are using SwiftUI as an entry point to our application and attaching appdelegate using NSApplicationDelegateAdaptor. We are using NSViewControllerRepresentable to add a View Controller to the hiracrchy so that we can store intance of viewcontroller and add content to it programatically . @main struct TWMainApp: App { @NSApplicationDelegateAdaptor private var appDelegate: TWAppDelegate internal var body : some Scene { TWInitialScene () } } TWInitialScene : public struct TWInitialScene : Scene { public var body : some Scene { WindowGroup { TWInitialView () } } } TWInitialView : struct TWInitialView : View { @Environment(\.scenePhase) private var scenePhase var body : some View { TWAppKitToSwiftUIBridge () } } TWAppKitToSwiftUIBridge : struct TWNSKitToSwiftUIBridge : NSViewControllerRepresentable { func makeNSViewController(context: Context) -> TWNSViewController { let view_hierarchy : TWNSViewController view_hierarchy = TWStaticContext.sViewController return view_hierarchy } func updateNSViewController(_ nsViewController: TWNSViewController, context: Context) { } } @objc public class TWStaticContext : NSObject { public static let sViewController = TWNSViewController () public override init () {} @objc public static func GetViewController () -> TWNSViewController { return TWStaticContext.sViewController } } public class TWNSViewController : NSViewController { override public func viewDidLoad () { super.viewDidLoad () } } To add content to the hirarchy we are accessing viewcontroller's intance and adding content to it like this : public func PaintInitialScreen () { let label = NSTextField(labelWithString: "TW window") label.frame = NSRect(x: 100, y: 200, width: 200, height: 200) // Adding content to viewcontroller TWStaticContext.sViewController.view.addSubview(label) } We are using this approach because we have a contraint in our application that we have to update UI programatically and on compile time we dont know what we want to show . We will be adding content on runtime based on how many button we want, what label we want , where to place it etc. When we were using purely appKit application, doing things programatically was simple but since SwiftUI is a declarative application we have to use above approach. Rational for shifting to SwiftUI entry point is that we want our application to be future safe and since apple is more inclined to SwiffUI, we want to design our entry flow to use SwiftUI entry point . And SwiftUI being declarative, we are using appKit to add content to hiracrchy programtically. We have used similar apprach in iOS also , where are using UIApplicationDelegateAdaptor inplace of NSApplicationAdaptor . And UIViewControllerReprestable in place of NSViewControllerRepresentable. Is this right approach to use ?

I want to add a tool bar (setting search )to my app just like the apple file app using pure swiftUI, is it possible, if not, can i using a UIKit to implement it. struct MainView: View { var body: some View { TabView { Tab("View 1", systemImage: "square.grid.3x2") { View1() } Tab("View 2", systemImage: "square.grid.2x2") { View2() } } .tabViewStyle(.sidebarAdaptable) }

How can I put one list item at the top and another one at the bottom, retaining the NavigationView functionality? Here is a simple app: struct ContentView: View { var body: some View { NavigationView { Sidebar() } } } struct Sidebar: View { @State private var isActive = true var body: some View { List { NavigationLink(isActive: $isActive) { HomeView() } label: { Text("Home") } NavigationLink { SettingsView() } label: { Text("Settings") } } } } struct HomeView: View { var body: some View { VStack {} .navigationTitle("Home") } } struct SettingsView: View { var body: some View { VStack {} .navigationTitle("Settings") } } Which looks like this: My initial though was to put a Spacer() between each NavigationLink, but it results in an unexpected view: What i can do: Place an empty VStack between each NavigationLink with a hard-coded height like this: VStack {}.frame(height: 275) Which looks like this: But it wouldn't work if a user would want to increase the height of a window. I could disable window resizing which is kind of fine, but not the most optimal. Another obvious option was to replace the List with a VStack, but with this approach the styling of the NavigationLink gets broken and it does not get highlighted when I click on it. It looks like this: P.S. I know that NavigationView is deprecated, but i want to support macOS 12.0.

Hello! We can animate Text color via foregroundStyle very nicely in SwiftUI like so: Text("Some text here") .foregroundStyle(boolValue ? Color.green : Color.blue) withAnimation { boolValue.toggle() } However, if the foregroundStyle is a gradient, the color of the Text view changes immediately without animation. The code below works to animate a gradient foregroundStyle on an SF Symbol, but it does not work when applied to a Text view. Is it possible to animate a Text view foregroundStyle between gradient values? Image(systemName: "pencil.circle.fill") .foregroundStyle(boolValue ? .linearGradient(colors: [.red, .orange], startPoint: .top, endPoint: .bottom) : .linearGradient(colors: [.green, .blue], startPoint: .top, endPoint: .bottom)) Thanks for your help!

Hello everyone, I am developing an app that focuses on self-reflection, journaling, and personal insights. Users can write their thoughts, receive guided suggestions, and engage in meaningful interactions. Over time, I have refined the app to emphasize well-being and mindfulness. Initially, I categorized it under Lifestyle, then tried Entertainment, but I am unsure which category best fits its purpose. I would appreciate any insights on choosing the right category or refining the app’s positioning to better align with platform guidelines. Has anyone faced a similar challenge? Looking forward to your thoughts. Thank you!

I'm seeing a build failure when archiving for TestFlight due to removing landscape support from the project. I see tons of apps that lock portrait in the app store. Is this a new requirement for apps compatible with both iPhone and iPad? What is the best approach if I am focused on portrait? Make the app iPhone only?

Hello, Appeal Ticket: APL149985 Thank you for your patience as we considered your appeal. The App Review Board determined that the original rejection feedback was valid. Your app does not comply with: 4.3(a) - Design During our review, we found that this app duplicates the content and functionality of other apps submitted to the App Store, which is considered a form of spam and not appropriate for the App Store. Apps submitted to the App Store should be unique and should not duplicate other apps. We encourage you to create a unique app to submit to the App Store. For more information about developing apps for the App Store, visit the Develop section of the Apple Developer website. We appreciate your efforts to resolve this issue and look forward to reviewing your revised submission. Best regards, Leo App Review Board BlockQuote a Blockchain based slg game got 4.3 a, I think the reviewer should know some thing about blockchain. 您好，我已经重新提交了一个版本的应用，和之前版本已经不同了，目前游戏的所有代码都是我自己写的，第三方的所有代码都被我移除了，所以代码上重复了其他游戏的是完全不存在的。 至于游戏玩法上，新的自定义技能冲榜系统，玩家可以通过“抽卡-编辑阵容-连续挑战”的方式，在遇到瓶颈时自定义技能突破关卡，这个玩法绝对是开创性的，因为已知的所有slg游戏的技能都是官方设计决定的，但是在我设计的这个玩法上，理论上所有的技能都将由玩家设计出来，这差别之大，正如区块链开创了一种崭新的去中心化的时代，和原有中心化的模式是完全不同的，据我所知，目前市面上不存在任何一款去中心化的slg游戏。但是您，尊贵的审核人员居然认为这样一款开创性的游戏是和其他中心化游戏是一样的，类同的，我相信苹果作为全球最伟大的科技公司，官方工作人员都是很专业的，都是很有见识的，都是主张创新的，主张玩家能获得独特的高质量的体验，但是这个拒绝让我疑惑。

Scenario is when keyboard is opened within the app being developed then switch to other app, for instance, Notes app and create a note to enable keyboard from there. While the Notes app keyboard is active switch back to the developed app the keyboard in it is dismissed. Any thoughts?Thanks

My app is being rejected and all I'm being told is that it is spam. I've tried improving various aspects of the game, but I just receive the same copy and paste rejection message each time. I have no idea if I'm moving in the right direction or what part of my game needs to be changed or improved. Is there a game quality benchmark document or some kind of resource I can use to better understand why my game is being rejected and how to bring it to a level that meets apple's standards.

I'm observing that when a silent push notification is sent to our app, is is started up in the background for 30 seconds before being suspended until the app is launched by the user. This causes data to persist from the silent push notification to the user app launch. I couldn't find documentation on this behavior for silent push notifications, and was wondering if it's possible to have the app terminate after handling the silent push notification. Is there documentation on the general flow of silent push notifications as well? I'm able to handle the edge cases if the app has to be suspended until user launch, but just want to confirm that this is the expected behavior before I go about handling it this way.
