Novice SwiftUI developer can't make network call
I'm trying to use URL structure in the foundation framework and it is failing to build, returning a nil value. Could it be trying to evaluate the string I am giving it as a variable for its argument at build time? Is there a test argument I can give URL to see if it can return a non-nil value? (of URL type)?

@State variable returns empty despite being set in .onAppear function
With the code below, JSON data is parsed and is stored in the variable data in the .onAppear function, however an empty set of data is passed to the Content view. How can that be fixed so that the JSON data passes to the DataView? struct ContentView: View { @State var data: [Data] @State var index: Int = 0 var body: some View { VStack { DataView(data: data[index]) } .onAppear { let filePath = Bundle.main.path(forResource: "data", ofType: "json") let url = URL(fileURLWithPath: filePath!) data = getData(url: url) } } func getData(url: URL) -> [Data] { do { let data = try Data(contentsOf: url) let jsonDecoded = try JSONDecoder().decode([Data].self, from: data) return jsonDecoded } catch let error as NSError { print("Fail: \(error.localizedDescription)") } catch { print("Fail: \(error)") } return [] } }

Testing In-App Purchases
Hi, I have a couple of questions in regards to testing in-app purchases. I tested the subscription on a device but I'm not sure how to reset so I can test again. I didn't see the subscription in device settings or in Debug -> StoreKit -> Manage Subscriptions window. Additionally, I was wondering if there was a way to detect the subscription being made. I implemented this, but I'm not sure if that will work: .onChange(of: Product.SubscriptionInfo.RenewalState.subscribed) { if Product.SubscriptionInfo.RenewalState.subscribed == .subscribed { } }

Video Playback on iOS 18 public release is seriously flawed
Video Playback on iOS 18 public release is asinine. I use video playback to show slow-motion video frame by frame to my students and the video can only be shown at like 3/5 of the screen size (just like Apple fouled up screenshot editing about a year ago) If you try to view video in the full screen you can’t scrub through and see time stamps or play frame by frame sliding left to right. It’s absolutely ridiculous. 2 out of 3x the video timeline finishes fully right and I haven’t watched the full clip. Here’s a video showing the issue how at the small default size I can see the entire timeline and play the full video from beginning to end, but when I go to full screen and/or zoom in or move the screen around the timeline doesn’t work and you can’t scroll through the full video! Need the video to not condense in size on the screen and play the full height / width of the screen. Also not have the text of the location showing above the screen. Way too much clutter. The reduced size of the video for editing issue started with photos several updates ago and now Apple idiotically brought a terrible flaw from photos to videos as well. Ugh.

Complex Swift Data Relationships...
I am struggling with exactly how to set up SwiftData relationships, beyond the single relationship model... Let's say I have a school. Each school offers a set of classes. Each class is taught by one teacher and attended by several students. Teachers may teach more than one class, but only at one school. Similarly students may attend more than one class, but only at one school. Classes themselves may be offered at more than one school. Can someone create a class for School, SchoolClass, Teacher, and Student with id, name, and relationships... I have tried it unsuccessfully about 10 different ways at this point. My most recent is below... I am struggling getting beyond a school listing in the app, and I'll cross that bridge next. I am just wondering if all the trouble I am having is because I am not smart with the class definitions. And wondering if this is to complex for SwiftData and CoreData is the requirement. This is not a real app, just my way of really trying to get a handle on Swift Data models and Navigation. I am very new to Swift, and will take any and all suggestions with enthusiasm! Thanks for taking the time. import Foundation import SwiftData @Model class School: Identifiable { var id: UUID = UUID() var name: String var mascot: String var teachers: [Teacher] var schoolClasses: [SchoolClass] init (name: String, mascot: String = "", teachers: [Teacher] = [], schoolClasses: [SchoolClass] = []) { self.name = name self.mascot = mascot self.teachers = teachers } class SchoolClass: Identifiable { var id: UUID = UUID() var name: String var teacher: Teacher? var students: [Student] = [] init (name: String, teacher: Teacher? = nil, students: [Student] = []) { self.name = name self.teacher = teacher self.students = students } } class Teacher: Identifiable { var id: UUID = UUID() var name: String var tenured: Bool var school: School? var students: [Student] = [] init (name: String, tenured: Bool = false, students: [Student] = []) { self.name = name self.tenured = tenured self.students = students } } class Student: Identifiable { var id: UUID = UUID() var name: String var grade: Int? var teacher: Teacher? init (name: String, grade: Int? = nil, teacher: Teacher? = nil) { self.name = name self.grade = grade self.teacher = teacher } } }

.onAppear and .task code not running
Hi, I have the following code, which for some reason is not working as expected. I have an .onAppear and a .task function that isn't running, which I can see isn't running because nothing is printing. Any guidance would be greatly appreciated. Thank you. struct ContentView: View { var body: some View { ZStack { switch view { case .view1: View1() case .view2: View2() case .view3: View3() case .view4: View4() case .view5: View5() default: SubscriptionStoreView(groupID: "") } } .onAppear() { view = .view6 print("test 1") } .task { print("test") await refreshPurchasedProducts() } } func refreshPurchasedProducts() async { // Iterate through the user's purchased products. for await verificationResult in Transaction.currentEntitlements { switch verificationResult { case .verified(let transaction): print("verified") case .unverified(let unverifiedTransaction, let verificationError): print("unverified") default: print("default") } } } }

Design Spam 4.3
Hello So I have an application which is in the Apple store. I wanted to fixe some issue therefore i created update build with the following: • Reworked Character Physics: Improved responsiveness and movement for smoother, more controlled gameplay. • Bug Fixes & Performance Enhancements: Fixed critical issues affecting gameplay consistency and stability. Players will now experience better performance and more accurate controls. • Mac Catalyst Fixes: Improved support for macOS, fixing issues related to UI scaling and responsiveness. The changes above are basically all there is. Now it seems that i am not able to pass review as it constantly marks design spam and not give anything in particular. Whats up with that ?

Subscriptions Not Displaying
I have a subscription group with two individual subscriptions configured but when trying to load the SubscriptionStoreView I get the error: "Subscription Unavailable: The subscription is unavailable in the current storefront." When I try to load the ProductView, it appears to be stuck in a loading screen. I am running the app on a device that is signed into a sandbox account. Any guidance would be greatly appreciated. Thank you.

Launch screen more vibrant in iOS18?
Hi! I've detected that in iOS18 launch screen colors differs from the defined ones, that is, if I create a launch screen with a color like #ff0000 (red) and the initial view controller is a view controller with the same color as background, I can see the transition between launch screen and the initial view controller because the launch screen color is different from the other one (dark in this case). I've tested it with several colors: left side is the launch screen and right side is the initial view controller. Both views created with IB using the same colors (it also happens with background images using colors) Is this an intentionall behavior? If so, theres a way to disable it? I need the transition between the launch screen and my initial view controller to be non perceptible... Thanks!

How can this be resolved - load_eligibility_plist: Failed to open //private/var/db/os_eligibility/eligibility.plist: Operation not permitted(1)
I'm programming my constraints in my video game, which is working good so far until I ran into my most important interactive storyboard. I have three buttons that move back and forth on the Y position each time they are hit. The buttons Y positions only change to view.safeAreaLayoutGuide.centerYAnchor, constant: 100 or view.safeAreaLayoutGuide.centerYAnchor, constant: 200 or view.safeAreaLayoutGuide.centerYAnchor, constant: 300 The strange part is the button that is in the Y 100 stays visible and I can hit the button that is in the Y 100. The buttons in the Y 200 and Y 300 positions are visible until after one or two hits, then the button that is in Y 300 position disappears, then after another hit or two the button that is in the Y 200 position disappears but the button that is in the Y 100 is still visible. I cleared all my constraints to narrow it down to clear view of the constraints that is causing the problem. I do not think this Log Noise. Below is the error log: load_eligibility_plist: Failed to open //private/var/db/os_eligibility/eligibility.plist: Operation not permitted(1) 1 Unable to simultaneously satisfy constraints.

Guideline 4.3(a) - Design - Spam - automatic rejection
I previously written here, and some advices were to appeal to rejection sending them message describing uniqueness of the app. Nothing is working. In short, i have a vpn app (of course by design shares some concept with other apps that are in the app store). But since the rejection i have completely changed the ui, added built in browser, p2p messenger so users could interact with each other without any interference. The app is completely free with no ads. I thought this is it, there's no way it would reject this time, but... i get a notification with rejection repeating the same old message. I'm extremely frustrated and don't know what to do. Tried changing the logo of the app, the name to "Incognito - Messenger, VPN", app store screenshots. I've already appealed with screenshots describing unique features that other vpn apps don't have, but the message just repeats from app review team. Submission ID: 1a49ee0b-c4e2-4a36-8372-e4d3b9a8b13f Does anybody have an advice what i can do?

Scrollview and a background image set to scaledToFill....
I've been beating my head against the wall over a scrollview issue where the top and bottom are cut off in landscape mode. Portrait mode - everything runs swimmingly. The moment I flip the iPad on its side, though, I lose about a quarter of the view on the top and bottom. I thought this was something to do with framing or such; I ran through a myriad of frame, padding, spacer, geometry...I set it static, I set it to dynamically grow, I even created algorithms to try to figure out how to set things to the individual device. Eventually, I separated the tablet and phone views as was suggested here and on the Apple dev forums. That's when I started playing around with the background image. Right now I have.... ZStack { Image("background") .resizable() .scaledToFill() .ignoresSafeArea() ScrollView { VStack(spacing: 24) {.... The problem is the "scaledToFill". In essence, whenever THAT is in the code, the vertical scrollview goes wonky in landscape mode. It, in essence, thinks that it has much more room at the top and the bottom because the background image has been extended at top and bottom to fill the wider screen of the iPad in landscape orientation. Is there any way to get around this issue? The desired behavior is pretty straightforward - the background image fills the entire background, no white bars or such, and the view scrolls against it.

CloudKit not storing or updating public data in real time.
My newly released App Snapshot-Chess-Move, #1592848671, is not creating a public database of chess moves as I expect. What steps do I need to do inorder for my App to be using a public database. It appears as if each of my iOS devices, iPhone, iPad and Mac mini each have a private database of chess moves. When I change my data on the iPad, I expect the new data to appear (with slight delays) on the Mac.. I do not know what to do next. Please help me. This was working in Development mode but not in Production when I submitted my App for release. UPDATE: The cloud data is copied locally to a @Quary variable and updated by using .insert, .delete and .save commands. So, I deleted and re-downloaded my apps on each device, iPad, iPhone, and Mac and obtained the same cloud data. So how do users get the most recent copy of the cloud. Do they need to delete their App and start over? Is there a .update command that can do this updating for me? Also, I pushed the App out of the background and restarted the App to obtain the updated cloud data.

iPad/iPhone - Display best practices….
So…I am hitting a wall here and could use some guidance towards best practice. I’ve developed an app in Xcode/SwiftUI that renders just fine on the iPhone - text, images, buttons, frames…everything is nicely centered on the screen or scrolls where and when I want. The iPad though…not so much. I’m having issues with tops and bottoms being cut off in scrollviews. These are just straight up text screens too - the ones with other elements/controls…they’re rendering fine. I’ve tried a mix of geometry, vstack, scrollview, padding, spacers…the lot of it. Nothing I seem to do works - the views do not want to fill and fit properly. And, of course, the issue becomes worse the moment you flip the iPad into landscape view. Or use the 13” models. I’d imagine others are battling these issues as well and found solutions, so I decided to hit up the brain trust.

IS THE SWiPE LEFT CAMERA MODE REALLY IMPORTANT?
I have really examined the swipe left Camera function mode and sincerely believe it is no more important especially when there no option in the settings to turn it on or off. I will highly recommend a total scrap in the iOS 26 or if possible a function to activate and deactivate it.

How to attribute/credit Apple Fonts added to app?
My app lets users create things with text, and I've included Apple fonts so users can format their text with them. These were fonts I found in the Font Book app that comes with macOS. My assumption is that these, like the San Francisco font, can be distributed with apps. Do I need to attribute these fonts to their creators and publish a license in my "About" page? If so, where do I find the license(s) and what is the proper way of publishing them? Is there anything else I should know? Please let me know if this should've been posted under a different topic and tag

Color folder and tags
I’m delighted with the introduction of new color folders. Although, I can’t help but wonder why we still need both color folders and tags. Aren’t the color folders sufficient for our needs?

Liquid Glass material behaviour question
I have two views I've applied Liquid Glass to in Swift UI. I've noticed that depending on the height of the view the material changes and I'm not sure why. See the attached screenshot. Both views add the liquidGlass style in the same way but behave very differently on the same background. Ideally I'd like them to look the same as the bottom one. Is that the same as the clear style?

Urgent Feature Request: Auto-Hide Home Bar in iOS 18.x Based on iOS 26 Beta Experience
Hello Apple Engineering Team and Fellow Developers, I’ve been using iOS 26 beta from day one and closely following all its improvements. One feature that significantly enhances the user experience is the automatic hiding of the Home Bar (the bottom navigation indicator) after a few seconds of inactivity in menus and apps. This subtle but powerful UI behavior not only increases immersion but also reduces distractions, making navigation smoother and visually cleaner. I strongly urge the Apple team to integrate this feature into the upcoming iOS 18.6 update. Bringing this polished interaction to iOS 18 users would greatly improve usability and keep the interface modern and elegant. Thank you for your continuous efforts in refining iOS. Looking forward to seeing this improvement officially adopted soon! Best regards, [ERFANEX]
