A method in my app now requires the override keyword when compiling with Xcode 26 beta / iOS 26 SDK, but if I add it, the current official Xcode 16.4 (iOS 18 SDK) throws a compile error. It's about 'toggleSidebar(_:)' in UIViewController.
The problem is:
Apple expects our apps to be ready for iOS 26 launch this fall, so I need to be actively developing and testing in the Xcode 26 beta now.
At the same time, I still need to submit updates to the App Store using the current official Xcode 16.4 until iOS 26 officially launches.
I'm using a single .xcodeproj file and can't keep manually adding/removing -DIOS_SDK_26_OR_LATER in Build Settings multiple times a day.
How to fix it and why isn't there a straightforward #if sdk(>=26.0) type of check for compile-time in Swift?
It's really frustrating to manage this override conflict.

I have discovered a gap in my understanding of user selected URLs in iOS, and I would be grateful if someone can put me right please.
My understanding is that a URL selected by a user can be accessed by calling url.startAccessingSecurityScopedResource() call. Subsequently a call to stopAccessingSecurityScopedResource() is made to avoid sandbox memory leaks.
Furthermore, the URL can be saved as a bookmark and reconstituted when the app is run again to avoid re-asking permission from the user.
So far so good.
However, I have discovered that a URL retrieved from a bookmark can be accessed without the call to url.startAccessingSecurityScopedResource(). This seems contrary to what the documentation says here
So my question is (assuming this is not a bug) why not save and retrieve the URL immediately in order to avoid having to make any additional calls to url.startAccessingSecurityScopedResource?

You can copy and paste the code below into a new iOS project to illustrate this. Having chosen a folder, the 'Summarise folder without permission' button fails as expected, but once the 'Retrieve URL from bookmark' has been pressed, it works fine.
import SwiftUI
import UniformTypeIdentifiers
struct ContentView: View {
@AppStorage("bookmarkData") private var bookmarkData: Data?
@State private var showFolderPicker = false
@State private var folderUrl: URL?
@State private var folderReport: String?
var body: some View {
VStack(spacing: 20) {
Text("Selected folder: \(folderUrl?.lastPathComponent ?? "None")")
Text("Contents: \(folderReport ?? "Unknown")")
Button("Select folder") {
showFolderPicker.toggle()
}
Button("Deselect folder") {
folderUrl = nil
folderReport = nil
bookmarkData = nil
}
.disabled(folderUrl == nil)
Button("Retrieve URL from bookmark") {
retrieveFolderURL()
}
.disabled(bookmarkData == nil)
Button("Summarise folder with permission") {
summariseFolderWithPermission(true)
}
.disabled(folderUrl == nil)
Button("Summarise folder without permission") {
summariseFolderWithPermission(false)
}
.disabled(folderUrl == nil)
}
.padding()
.fileImporter(
isPresented: $showFolderPicker,
allowedContentTypes: [UTType.init("public.folder")!],
allowsMultipleSelection: false
) { result in
switch result {
case .success(let urls):
if let selectedUrl = urls.first {
print("Processing folder: \(selectedUrl)")
processFolderURL(selectedUrl)
}
case .failure(let error):
print("\(error.localizedDescription)")
}
}
.onAppear() {
guard folderUrl == nil else { return }
retrieveFolderURL()
}
}
func processFolderURL(_ selectedUrl: URL?) {
guard selectedUrl != nil else { return }
// Create and save a security scoped bookmark in AppStorage
do {
guard selectedUrl!.startAccessingSecurityScopedResource() else { print("Unable to access \(selectedUrl!)"); return }
// Save bookmark
bookmarkData = try selectedUrl!.bookmarkData(options: .minimalBookmark, includingResourceValuesForKeys: nil, relativeTo: nil)
selectedUrl!.stopAccessingSecurityScopedResource()
} catch {
print("Unable to save security scoped bookmark")
}
folderUrl = selectedUrl!
}
func retrieveFolderURL() {
guard let bookmarkData = bookmarkData else {
print("No bookmark data available")
return
}
do {
var isStale = false
let url = try URL(
resolvingBookmarkData: bookmarkData,
options: .withoutUI,
relativeTo: nil,
bookmarkDataIsStale: &isStale
)
folderUrl = url
} catch {
print("Error accessing URL: \(error.localizedDescription)")
}
}
func summariseFolderWithPermission(_ permission: Bool) {
folderReport = nil
print(String(describing: folderUrl))
guard folderUrl != nil else { return }
if permission { print("Result of access requrest is \(folderUrl!.startAccessingSecurityScopedResource())") }
do {
let contents = try FileManager.default.contentsOfDirectory(atPath: folderUrl!.path)
folderReport = "\(contents.count) files, the first is: \(contents.first!)"
} catch {
print(error.localizedDescription)
}
if permission { folderUrl!.stopAccessingSecurityScopedResource() }
}
}
This happens when trying to connect to my development web server. The app works fine when connecting to my production server.
The production server has a certificate purchased from a CA.
My development web server has a locally generated certificate (from mkcert).
I have dragged and dropped the rootCA.pem onto the Simulator, although it doesn't indicate it has been loaded the certificate does appear in the Settings app and is checked to be trusted.
I have enabled "App Sandbox" and "Outgoing connections (Client)".
I have tested the URL from my local browser which is working fine.
What am I missing?
I have been trying for almost a week to get my app approved. It is like the Submission team doesn't even read my notes. The first complaint is that my app was for a specific business and shouldn't be for the general public. This is true, so I put in the notes that I had requested private distribution and I filled out the request for the app to be distributed privately. The review notes say that I need to distribute my app privately. This is very frustrating.
Also, they say the login button doesn't work. It works for everyone that uses it in the Test Flight. One nuance we have is that our servers will not respond to IP addresses that orginate outside of the US. I have this in caps in the notes. They still say that the Login button doesn't work. The app was written for iPhones, yet they keep testing it on an iPad.
There doesn't seem to be any way to communicate with the submission team other than through the test notes and they don't seem to be reading these. Can anyone direct me to where I can get some help on this?
Thanks,
Jim

I have a transformation function that takes in data, executes some instructions, and returns an output. This function is dynamic and not shipped with the binary. Currently, I’m executing it using JavaScriptCore.JSContext, which works well, but the function itself is written in JavaScript.
Is there a way to achieve something similar using Swift – such as executing a dynamic Swift script, either directly or through other means? I know this is possible on macOS, but I’m not sure about iOS. I’ve also heard that extensions might open up some possibilities here. Any insights or alternative approaches would be appreciated.

Hi I have attempted to find a fix for my issue via documentation online and one phone support ( not code level support ) call to no end. I could continue to try various things but would like to see if someone else has encountered this issue and a fix for it.
Background: My Game app is live on App Store and has 1 classic leaderboard . I am now getting ready to submit an update to the app and it also entails adding a new recurring leaderboard. I added the leaderboard in App Store. I however have NOT uploaded my new build yet. I have also not added my leaderboards ( currently live and not live ) to any set.
When I try to submit scores using
GKLeaderboard.submitScore(_:context:player:leaderboardIDs:completionHandler:) to the new non-live leaderboard it works ( gives me no error )
When I try to load the scores from the new non-live leaderboard
GKLeaderboard.loadLeaderboards(IDs:completionHandler:)
loadEntries(for:timeScope:range:completionHandler:)
it fails. Error: "leaderboardID not found"
I could try ( and will )
uploading the new build to AppStore connect and associating the new leaderboard to it before testing again.
try associating each leaderboard to a set
Is there anything else that I should be aware of ?
Thanks in advance
Before I file a bug report I wanted to verify that I'm not missing something.
If I setup a view controller in a navigation controller and I add a view with a constraint that lines it up with the view controller's view's layoutMarginsGuide (leadingAnchor or trailingAnchor), in several cases the view will not line up with buttons added in the navigation bar. Under iOS 18 everything lines up as expected.
To demonstrate, create a new iOS project based on Swift/Storyboard. Setup the storyboard to show a UINavigationController with one UIViewController. Then in ViewController.swift (the one embedded in the navigation controller), use the following code:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .yellow
title = "Layout Margins"
let leftCancel = UIBarButtonItem(systemItem: .cancel)
navigationItem.leftBarButtonItem = leftCancel
let rightCancel = UIBarButtonItem(systemItem: .cancel)
navigationItem.rightBarButtonItem = rightCancel
let leftView = UIView()
leftView.backgroundColor = .blue
leftView.translatesAutoresizingMaskIntoConstraints = false
self.view.addSubview(leftView)
let rightView = UIView()
rightView.backgroundColor = .red
rightView.translatesAutoresizingMaskIntoConstraints = false
self.view.addSubview(rightView)
NSLayoutConstraint.activate([
leftView.widthAnchor.constraint(equalToConstant: 80),
leftView.heightAnchor.constraint(equalToConstant: 80),
leftView.leadingAnchor.constraint(equalTo: self.view.layoutMarginsGuide.leadingAnchor),
leftView.topAnchor.constraint(equalTo: self.view.layoutMarginsGuide.topAnchor),
rightView.widthAnchor.constraint(equalToConstant: 80),
rightView.heightAnchor.constraint(equalToConstant: 80),
rightView.trailingAnchor.constraint(equalTo: self.view.layoutMarginsGuide.trailingAnchor),
rightView.topAnchor.constraint(equalTo: self.view.layoutMarginsGuide.topAnchor),
])
}
}
This adds a "Cancel" button to both ends of the navigation bar and it adds two little square views lined up with the leading and trailing layout margins.
Here's the results:
iPad running iPadOS 26 beta 3 (note the misalignment). This is really jarring when trying to align another glass button below the cancel button:
iPad running iPadOS 18.5 (aligned just fine):
iPhone in portrait running iOS 26 beta (aligned just fine):
iPhone in landscape running iOS 26 beta (no alignment at all):
iPhone in portrait running iOS 18.5 (aligned just fine):
iPhone in landscape running iOS 18.5 (aligned just fine):
Under iOS 26 on an iPhone (simulator at least) in portrait, the cancel buttons line up with the colored squares. That's good. In landscape, the colored squares have much larger margins as expected (due to the larger safe areas caused by the notch), but the cancel buttons in the navigation bar are not using the same margins. This one is debatable. Under iOS 18 the cancel buttons use larger margins to match the larger safe area. But I can see why under iOS 26 they changed this since the navigation bar doesn't interfere with the notch. But it's inconsistent.
Under iOS 26 on an iPad (simulator at least), it's wrong in any orientation. Despite the lack of any notch or need for a larger safe area, the colored squares are indented just a bit more than the buttons in the navigation bar. I see no reason for this. Under iOS 18 everything lines up as expected.
My real question at this point: Is the mismatched margins on an iPad under iOS 26 between the buttons in the navigation bar and other views added to the view controller a likely bug or am I missing something?
I installed the third beta of Xcode 26 with Xcode 16.4 installed on my machine. Once Xcode 26 was installed, all of my previous simulators were wiped out, leaving only the default iOS 26 simulators. I cannot create new simulators for iOS versions below 26. Here are my failed attempts to fix the issue:
Restarted Xcode 16.4 and my machine
Reinstalled the iOS 18.5 runtime
Uninstalled Xcode 26 and iOS 26 runtime
Reinstalled Xcode 16.4
Now, I literally cannot use a simulator in Xcode 16.4. Here is what I see when I try to create a new simulator in Xcode 16.4:
According to Xcode, the iOS 18.5 runtime is installed, so I have no idea what is going on. Is this a known issue? And how do I get Xcode 16.4 working with the iOS simulator?
I'm working on an app where a user needs to select a video from their Photos library, and I need to get the original, unmodified HEVC (H.265) data stream to preserve its encoding.
The Problem
I have confirmed that my source videos are HEVC. I can record a new video with my iPhone 15 Pro Max camera set to "High Efficiency," export the "Unmodified Original" from Photos on my Mac, and verify that the codec is MPEG-H Part2/HEVC (H.265).
However, when I select that exact same video in my app using PHPickerViewController, the itemProvider does not list public.hevc as an available type identifier. This forces me to fall back to a generic movie type, which results in the system providing me with a transcoded H.264 version of the video.
Here is the debug output from my app after selecting a known HEVC video:
⚠️ 'public.hevc' not found. Falling back to generic movie type (likely H.264).
What I've Tried
My code explicitly checks for the public.hevc identifier in the registeredTypeIdentifiers array. Since it's not found, my HEVC-specific logic is never triggered.
Here is a minimal version of my PHPickerViewControllerDelegate implementation:
import UniformTypeIdentifiers
// ... inside the Coordinator class ...
func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
picker.dismiss(animated: true)
guard let result = results.first else { return }
let itemProvider = result.itemProvider
let hevcIdentifier = "public.hevc"
let identifiers = itemProvider.registeredTypeIdentifiers
print("Available formats from itemProvider: \(identifiers)")
if identifiers.contains(hevcIdentifier) {
print("✅ HEVC format found, requesting raw data...")
itemProvider.loadDataRepresentation(forTypeIdentifier: hevcIdentifier) { (data, error) in
// ... process H.265 data ...
}
} else {
print("⚠️ 'public.hevc' not found. Falling back to generic movie type (likely H.264).")
itemProvider.loadFileRepresentation(forTypeIdentifier: UTType.movie.identifier) { url, error in
// ... process H.264 fallback ...
}
}
}
My Environment
Device: iPhone 15 Pro Max
iOS Version: iOS 18.5
Xcode Version: 16.2
My Questions
Are there specific conditions (e.g., the video being HDR/Dolby Vision, Cinematic, or stored in iCloud) under which PHPickerViewController's itemProvider would intentionally not offer the public.hevc type identifier, even for an HEVC video?
What is the definitive, recommended API sequence to guarantee that I receive the original, unmodified data stream for a video asset, ensuring that no transcoding to H.264 occurs during the process?
Any insight into why public.hevc might be missing from the registeredTypeIdentifiers for a known HEVC asset would be greatly appreciated. Thank you.
In TabView, when I open a view in a Tab, and I switch to another Tab, but the View lifecycle of the view in the old Tab is still not over, and the threads of some functions are still in the background. I want to completely end the View lifecycle of the View in the previously opened tab when switching Tab. How can I do it? Thank you!
We are preparing builds using Xcode 16.0 given we have a large set of users on iOS 12.
Now we have doubts wether we will run into issues if we ship using it (even if it compiles, archives and uploads successfully) given the table columns and content has changed since the last time we checked this table: https://developer.apple.com/support/xcode/.
1- Is the Deployment Targets range for Xcode 16 value correct for iOS? (On the 24th of February it had iOS 12-18, now it has iOS 15-18)
2- Are we OK to ship for iOS 12 using xcode 16.3?
Thanks,
Joao Garcia
I need a layout where I have a ScrollView with some content, and ScrollView has full screen background image. Screen is pushed as detail on stack.
When my screen is pushed we display navigation bar. We want a new scrollEdgeEffectStyle .soft style work. But when we scroll the gradient blur effect bellow bars is fixed to top and bottom part of the scroll view background image and is not transparent. However when content underneath navigation bar is darker and navigation bar changes automatically to adapt content underneath the final effect looks as expected doesn't use background image.
Expected bahaviour for us is that the effect under the navigation bar would not use background image but would be transparent based on content underneath.
This is how it is intialy when user didn't interact with the screen:
This is how it looks when user scrolls down:
This is how it looks when navigation bar adapts to dark content underneath:
Minimal code to reproduce this behaviour:
import SwiftUI
@main
struct SwiftUIByExampleApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
struct ContentView: View {
var body: some View {
NavigationStack {
ScrollView(.vertical) {
VStack(spacing: 0.0) {
ForEach(1 ..< 101, id: \.self) { i in
HStack {
Text("Row \(i)")
Spacer()
}
.frame(height: 50)
.background(Color.random)
}
}
}
.scrollEdgeEffectStyle(.soft, for: .all)
.scrollContentBackground(.hidden)
.toolbar {
ToolbarItem(placement: .title) {
Label("My Awesome App", systemImage: "sparkles")
.labelStyle(.titleAndIcon)
}
}
.toolbarRole(.navigationStack)
.background(
ZStack {
Color.white
.ignoresSafeArea()
Image(.sea)
.resizable()
.ignoresSafeArea()
.scaledToFill()
}
)
}
}
}
extension Color {
static var random: Color {
Color(
red: .random(in: 0...1),
green: .random(in: 0...1),
blue: .random(in: 0...1)
)
}
}
We've also tried using ZStack instead of .background modifier but we observed the same results.
We want to basically achieve the same effect as showcased here, but with the static background image:

Hello Team,
I try to delete photo from Photos for that i used this method,
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
[PHAssetChangeRequest deleteAssets:@[assetToDelete]];
completionHandler:^(BOOL success, NSError *error) {
}];
This method pops up a dialog with Don't Allow or Delete. But some time in some iPhones not respond PHAssetChangeRequest deleteAssets method that's why that completionHandler not called because of that i can't perform any operation of PHPhotoLibrary then after.
If I restart my iPhone then it works. Many users of my app complained about this issue. I have an iPhone 11 with iOS 15.3. But some iOS 12,14,16 users also face the same issue.
So what exact issue is there? Is it related to iOS or a method?
Thanks,
Ankur

Hi I recently installed iOS 26 but did not make a backup, how can I get iOS 18 without losing any data?
I present a view in a sheet that consists of a navigation stack and a scroll view which has a photo pushed to the top by setting .ignoresSafeArea(edges: .top). The problem is the top of the photo is blurry due to the scroll edge effect. I would like to hide the scroll edge effect so the photo is fully visible when scrolled to the top but let the effect become visible upon scrolling down. Is that possible?
struct ContentView: View {
@State private var showingSheet = false
var body: some View {
VStack {
Button("Present Sheet") {
showingSheet = true
}
}
.sheet(isPresented: $showingSheet) {
SheetView()
}
}
}
struct SheetView: View {
@Environment(\.dismiss) private var dismiss
var body: some View {
NavigationStack {
ScrollView {
VStack {

.resizable()
.scaledToFill()
}
}
.ignoresSafeArea(edges: .top)

Hello Developer Forums Team,
I’ve seen that some banking apps prevent screenshots on certain sensitive screens. I’m working on a similar feature in my SDK and want to confirm if my implementation complies with App Store guidelines.
Since there’s no public API to block screenshots, I’m using a workaround based on the secure rendering behavior of UITextField (isSecureTextEntry = true). I embed my custom content (e.g., a UITableView) inside the internal secure container of a UITextField, which results in blank content being captured during screenshots—similar to what some banking apps do.
Approach Summary
I create a UITextField
I detect its internal secure container by matching UIKit internal class names as strings
I embed my real UI content into that container
I do not use or call any private APIs, just match view class names via strings.
ScreenshotPreventingView.swift
final class ScreenshotPreventingView: UIView {
private let textField = UITextField()
private let recognizer = HiddenContainerRecognizer()
private var contentView: UIView?
public var preventScreenCapture = true {
didSet {
textField.isSecureTextEntry = preventScreenCapture
}
}
public init(contentView: UIView? = nil) {
super.init(frame: .zero)
self.contentView = contentView
setupUI()
}
private func setupUI() {
guard let container = try? recognizer.getHiddenContainer(from: textField) else { return }
addSubview(container)
NSLayoutConstraint.activate([
container.topAnchor.constraint(equalTo: topAnchor),
container.bottomAnchor.constraint(equalTo: bottomAnchor),
container.leadingAnchor.constraint(equalTo: leadingAnchor),
container.trailingAnchor.constraint(equalTo: trailingAnchor)
])
if let contentView = contentView {
setup(contentView: contentView, in: container)
}
DispatchQueue.main.async {
self.preventScreenCapture = true
}
}
private func setup(contentView: UIView) {
self.contentView?.removeFromSuperview()
self.contentView = contentView
guard let container = hiddenContentContainer else { return }
container.addSubview(contentView)
container.isUserInteractionEnabled = isUserInteractionEnabled
contentView.translatesAutoresizingMaskIntoConstraints = false
let bottomConstraint = contentView.bottomAnchor.constraint(equalTo: container.bottomAnchor)
bottomConstraint.priority = .required - 1
NSLayoutConstraint.activate([
contentView.leadingAnchor.constraint(equalTo: container.leadingAnchor),
contentView.trailingAnchor.constraint(equalTo: container.trailingAnchor),
contentView.topAnchor.constraint(equalTo: container.topAnchor),
bottomConstraint
])
}
}
HiddenContainerRecognizer.swift
struct HiddenContainerRecognizer {
private enum Error: Swift.Error {
case unsupportedOSVersion(version: Float)
case desiredContainerNotFound(_ containerName: String)
}
func getHiddenContainer(from view: UIView) throws -> UIView {
let containerName = try getHiddenContainerTypeInStringRepresentation()
let containers = view.subviews.filter { subview in
type(of: subview).description() == containerName
}
guard let container = containers.first else {
throw Error.desiredContainerNotFound(containerName)
}
return container
}
private func getHiddenContainerTypeInStringRepresentation() throws -> String {
if #available(iOS 15, *) {
return "_UITextLayoutCanvasView"
}
if #available(iOS 14, *) {
return "_UITextFieldCanvasView"
}
if #available(iOS 13, *) {
return "_UITextFieldCanvasView"
}
if #available(iOS 12, *) {
return "_UITextFieldContentView"
}
let currentIOSVersion = (UIDevice.current.systemVersion as NSString).floatValue
throw Error.unsupportedOSVersion(version: currentIOSVersion)
}
}
How I use it in my Screen
let container = ScreenshotPreventingView()
override func viewDidLoad() {
super.viewDidLoad()
container.preventScreenCapture = true
container.setup(contentView: viewContainer) //viewContainer is UIView in storyboard, in which all other UI elements are placed in e.g. UITableView
self.view.addSubview(container)
container.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
container.topAnchor.constraint(equalTo: self.view.topAnchor),
container.bottomAnchor.constraint(equalTo: self.view.bottomAnchor),
container.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),
container.trailingAnchor.constraint(equalTo: self.view.trailingAnchor)
])
}
What I’d Like to Confirm
Is this approach acceptable for App Store submission?
Is there a more Apple-recommended approach to prevent screen capture of arbitrary UI?
Thank you for your help in ensuring compliance.
I'm trying to update one of my apps to the new Liquid Glass effects using Xcode 26. Came across a weird issue in that I reproduced in an empty project on its own with a storyboard with a single segmented control on the initial viewController
I have a UISegmentedControl with 3 options. If I click index 2, while index 0 is selected, everything works as normal
However if I select index 1, and then index 2, it jumps back to index 0 instead of selecting 2. All the events fire as though I tapped index 0
I have a More button in my nav bar that contains a Delete action, and when you tap that I want to show a confirmation dialog before performing the deletion. In order words, I have a toolbar containing a toolbar item containing a menu containing a button that when tapped needs to show a confirmation dialog.
In iOS 26, you're supposed to add the confirmationDialog on the view that presents the action sheet so that it can point to the source view or morph out of it if it's liquid glass. But when I do that, the confirmation dialog does not appear. Is that a bug or am I doing something wrong?
struct ContentView: View {
