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 []
}
}

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)?
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 {
}
}
I have some questions about Liquid Glass and iOS 26 on the iPhone.
Routine scrolling transactions in any view are causing the title to change from Light Mode colors to Dark Mode colors. Is this now standard operation? The column headers are also displaying a black stripe across the top of the screen when scrolling. So why doesn't the display shift when in Dark Mode to Light mode?
Scrolling is causing everything in the header (navigation title, time, battery status, and wi-fi status) to change from black to white.
Is this an accessibility action that I may have turned on by accident?
I'm not very thrilled by this behavior!
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] = []

Running iOS 26.4 and now the smart display zoom feature is no longer showing on my 2024 RAM Uconnect 5 12” radio. Is there anyway to fix this issue?
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")
}
}
}
}
hi, i have an objc ipad application that use xib with zooming for adapt to the screen (until ios18) but with ipad os 26 will be displayed wrong
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.
Hello!
I'm currently working on Liquid Glass support for my app. I understand that starting with iOS 26, standard buttons like "Close" or "Done" have shifted from text buttons to using SF Symbols, as mentioned in the Human Interface Guidelines under "Icons".
However, on iOS 18 and earlier, the flat text button style remains the standard. I am unsure about the best approach for backward compatibility:
Branch by OS version: Keep text buttons for older OS versions and use SF Symbols for iOS 26+.
Concern: This increases the number of conditional branches, potentially reducing code readability and maintainability.
Adopt SF Symbols universally: Use SF Symbols for all versions.
Concern: I feel that SF Symbols do not fit well (look inconsistent or out of place) with the flat design language of iOS 18 and earlier.
What would be the recommended approach in this situation?
Hello everyone,
I’ve reached out to Apple’s review team multiple times, but unfortunately, I haven’t received any clear or specific guidance on why my app was rejected. My app has been rejected several times with the reason “Spam” under guideline 4.3, and I still don't understand exactly which part of the app is problematic.
Even after providing the necessary information about the data, I resubmitted the app, and after a few days, it quickly moved into "In Review" status, but then was rejected within seconds with the same “Spam” message.
I have sent over 13 messages asking for specific feedback, and all I get are vague responses saying “It’s spam, refer to 4.3, fix your app, and resubmit.” However, when I review the guidelines, I don’t see any specific reasons for rejection that apply to my app.
I’m particularly confused because my app is a VPN, and when I check the guidelines, I see that apps in categories like dating and others are saturated, but VPN apps are not. My app uses completely dedicated servers, and the IP addresses are not found in any other apps.
Still, my app keeps getting rejected. If anyone has encountered a similar issue or has any insight into what might be causing this, I would greatly appreciate it if you could provide detailed guidance on what specifically needs to be changed to get the app approved.
Thank you!
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)

Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(

Hi,
I would like to make an educational app for helping my students to learn about malaria diagnosis and need to put some animal icon.
In the tabview, is it possible to use system images like monkey, bird, mouse. I cannot see these animals in SF symbol list.
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?
I have many Apple devices, such as macbook, iPad and iPhone. It's very convenient for me to transfer files between devices. However, when I want to send files to my own device in public places, I often click on the wrong recipient because the list avatar keeps changing. I hope the list of recipients can be grouped One group is my own device (or the one I often send to), and the other group is other devices. When the user is about to send, the mouse will be in a relatively fixed and mentally expected area. I feel that this can reduce the probability of sending wrongly
We use SwiftUI's .tabViewBottomAccessory in our iOS apps for displaying an Audio MiniPlayer View (like in the Apple Music App).
TabView(selection: $viewModel.selectedTab) {
// Tabs here
}
.tabViewBottomAccessory {
if viewModel.showAudioMiniPlayer {
MiniPlayerView()
}
}
The Problem
This code works perfectly on iOS 26.0. When 'viewModel.showAudioMiniPlayer' is 'false', the accessory is completely hidden.
However, on iOS 26.1 (23B5059e), when 'viewModel.showAudioMiniPlayer' is 'false', the MiniPlayerView disappears, but an empty container remains, leaving a blank space above the tab bar.
Is this a known Bug in iOS 26.1 and are there any effective workarounds or should I just wait until Apple fixed it?
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.
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.
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]
I'm looking for a way to display a notification badge without showing a number—essentially, just an empty badge to indicate the presence of notifications. From my research, it seems like this functionality isn't available . Is there any workaround or method to achieve this?
