In beta 2 using layer.cornerRadius on a UIEffectView with the UIGlassEffect allowed you to change the corner radius of the view. In beta 3, this no longer works. WWDC videos indicate the right way to do this is to set the cornerConfiguration on the UIEffectView, but that API doesn't seem to be available yet. At this time it doesn't seem like theres a way to have a glass view that isn't pill shaped.

I have a few view controllers in a large UIKit application that previously started showing content right below the bottom of the top navigation toolbar.
When testing the same code on iOS 26, these same views have their content extend under the navigation bar and toolbar. I was able to fix it with:
if #available(iOS 26, *, *) {
self.edgesForExtendedLayout = [.bottom]
}
when running on iOS 26. I also fixed one or two places where the main view was anchored to self.view.topAnchor instead of self.view.safeAreaLayoutGuide.topAnchor.
Although this seems to work, I wonder if this was an intended change in iOS 26 or just a temporary bug in the beta that will be resolved.
Were changes made to the safe area and edgesForExtendedLayout logic in iOS 26? If so, is there a place I can see what the specific changes were, so I know my code is handling it properly?
Thanks!

All of these issues appear when the search controller is set on the view controller's navigationItem and the search controller's searchBar has its scopeButtonTitles set.
So far the following issues are affecting my app on iOS/iPadOS 26 as of beta 7:
When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to .integratedButton, and the searchBarPlacementAllowsToolbarIntegration is set to false (forcing the search icon to appear in the nav bar), on both iPhones and iPads, the scope buttons never appear. They don't appear when the search is activated. They don't appear when any text is entered into the search bar. FB19771313
I attempted to work around that issue by setting the scopeBarActivation to .manual. I then show the scope bar in the didPresentSearchController delegate method and hide the scope bar in the willDismissSearchController. On an iPhone this works though the display is a bit clunky. On an iPad, the scope bar does appear via the code in didPresentSearchController, but when any scope bar button is tapped, the search controller is dismissed. This happens when the app is horizontally regular. When the app on the iPad is horizontally compact, the buttons work but the search bar's text is not correctly aligned within the search bar. Quite the mess really. I still need to post a bug report for this issue. But if issue 1 above is fixed then I don't need this workaround.
When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to .stacked, and the hidesSearchBarWhenScrolling property of the navigationItem is set to false (always show the search bar), and this is all used in a UITableViewController, then upon initial display of the view controller on an iPhone or iPad, you are unable to tap on the first row of the table view except on the very bottom of the row. The currently hidden scope bar is stealing the touches. If you activate and then cancel the search (making the scope bar appear and then disappear) then you are able to tap on the first row as expected. The initially hidden scope bar also bleeds through the first row of the table. It's faint but you can tell it's not quite right. Again, this is resolved by activating and then canceling the search once. FB17888632
When the scopeBarActivation of UISearchController is set to .onSearchActivation, the preferredSearchBarPlacement of the navigationItem is set to integrated or .integratedButton, and the toolbar is shown, then on iPhones (where the search bar/icon appears in the toolbar) the scope buttons appear (at the top of the screen) the first time the search is activated. But if you cancel the search and then activate it again, the search bar never appears a second (or later) time. On an iPad the search bar/icon appears in the nav bar and you end up with the same issue as #1 above. FB17890125
Issues 3 and 4 were reported against beta 1 and still haven't been fixed. But if issue 1 is resolved on iPhone, iPad, and Mac (via Mac Catalyst), then I personally won't be affected by issues 2, 3, or 4 any more (but of course all 4 issues need to be fixed). And by resolved, I mean that the scope bar appears and disappears when it is supposed to each and every time the search is activated and cancelled (not just the first time). The scope bar doesn't interfere with touch events upon initial display of the view controller. And there are no visual glitches no matter what the horizontal size class is on an iPad.
I really hope the UIKit team can get these resolved before iOS/iPadOS 26 GM.
On iOS 18, while on a modal screen, if the scrolling starts on a button, that button gets pressed, outside of a modal this doesn't reproduce, also not reproducible on older iOS versions, neither on modals or outside of them.
The code to reproduce the issue:
import SwiftUI
struct ContentView: View {
@State var presentModal = false
var body: some View {
Button(action: {
presentModal = true
}, label: {
Text("open modal")
})
.sheet(isPresented: $presentModal, content: {
ScrollView {
ForEach(0..<100, id: \.self) { index in
Button(action: {
print("Button \(index) tapped!")
}) {
Text("Button \(index)")
.frame(maxWidth: .infinity)
.frame(height: 100)
.background(randomColor(for: index))
.padding(.horizontal)
}
}
}
})
}
func randomColor(for index: Int) -> Color {
let hue = Double(index % 100) / 100.0
return Color(hue: hue, saturation: 0.8, brightness: 0.8)
}
}
#Preview {
ContentView()
}

Zoom transition originating from inside tabViewBottomAccessory, when the binding passed to fullScreenCover's item is a Binding other than a "$-synthesized" binding, the animation fails with the following error (and crucially fails to perform the desired animation):
Starting a zoom transition from a nil view will trigger a fallback transition. To get the best possible teansition, be sure to provide a view that's visible and in a window.
What I want to do is pass a binding to a property inside an ObservableObject (or @Observable, but it doesn't matter) to hold the item representing the presentation. But this stopped working as of 26.1b4. It worked in 26.1b3 and in 26.0 (and 26.0.1)
Here's the gist of code that will reproduce the issue (I've omitted irrelevant details in the interest of brevity):
struct ContentView: View {
@Binding var presentation: PresentationDestination?
@Namespace private var animation
var body: some View {
// Omitted TabView stuff…
.tabViewBottomAccessory {
miniPlayer
.matchedTransitionSource(
id: "player",
in: animation
)
}
.fullScreenCover(
item: $presentation,
content: { _ in
fullScreenPlayer
.navigationTransition(
.zoom(
sourceID: "player",
in: animation
)
)
})
}
As you can see, ContentView takes a Binding to the presentation, but it matters how this binding is constructed.
This works:
@State private var presentation: PresentationDestination
…
ContentView(presentation: $presentation)
This fails (as does ObservableObject with @Published):
@Observable
class Router2 {
var presentation: PresentationDestination?
}
…
@State private var router2 = Router2()
…
ContentView(presentation: $router2.presentation)
Also, this fails:
@State private var presentation: PresentationDestination
…
ContentView(
presentation: .init(get: {
presentation
}, set: { newValue in
presentation = newValue
})
)
These differences are unexpected, of course. I consider this a regression in 26.1b4
I should add that if I move the source of the transition to somewhere outside tabViewBottomAccessory things seem to work fine.
In my visionOS app, I'm seeing this error in the console dozens of times. Anyone know what it means, or how to troubleshoot it?
Searching these forums and the usual other places hasn't come up with anything that seems relevant.
Hello,
I use CLGeocoder to get the CLLocationCoordinate2D and CLRegion for an address. Now that this is deprecated in OS 26, I don't see a replacement for that property on MKMapItem via MKMapItemRequest and PlaceDescriptor. I've filed FB19027378 on this issue.
Basically I have some addresses that have a street address, and others that just have a city. With CLGeocoder, when geocoding just the city, the CLRegion was set such that I could show my map zoomed out just right. I'm not sure how to do that now.
Thanks!
Our app was just rejected by Apple because they say the subscription management sheet never loads. It just spins indefinitely.
We're using StoreKit's manageSubscriptionsSheet view modifier to present the sheet, and it's always worked for us when testing in SandBox.
Has anyone else had this problem?
Given that it's Apple's own code that got us rejected, what's our path forward?
Hi! When building my app using Xcode 16, fast scrolling (using scrollViewProxy.scrollTo) a list would result in items not appearing even when scrolling stopped. This does not happen when the app is built with Xcode 15, even on iOS 18.
I'm also getting this error in the logs: List failed to visit cell content, returning an empty cell. - SwiftUICore/Logging.swift:84 - please file a bug report.
I have a simple example to demonstrate...
struct MyView: View {
var body: some View {
Text("WOW")
}
}
struct MyOtherView: View {
var body: some View {
NavigationStack {
Text("WOW")
}
}
}
On VisionOS, MyOtherView has a glass background effect that cannot be disabled. glassBackgroundEffect(displayMode: .never) .background(.clear), .foregroundColor(.clear), none of them work.
I then resorted to the SwiftUIIntrospect package to try set .clear on various child objects of the NavigationStack but nothing is working.
I am in control of my own glass containers. I have a couple with space between them, but with the NavigationStack it sets a background behind both of them ruining the effect.
This is what MyOtherView renders as:
I'm looking for it to be completely transparent except the text. Like the below layout.
For now I will have to roll my own navigation.
Hello, I have been trying for some time to change the color of native UITabBar in UITabBarController through UITabBarAppearance, but nothing works and the text is still black in the Xcode Beta 3 on iPadOS 26 while it works correctly in the previous OS versions.
Here is the code:
let color = UIColor.white
let stackedAppearance = UITabBarItemAppearance()
stackedAppearance.normal.iconColor = color
stackedAppearance.normal.titleTextAttributes = [
.foregroundColor: color
]
stackedAppearance.selected.iconColor = color
stackedAppearance.selected.titleTextAttributes = [
.foregroundColor: color
]
let inlineAppearance = UITabBarItemAppearance()
inlineAppearance.normal.iconColor = color
inlineAppearance.normal.titleTextAttributes = [
.foregroundColor: color
]
inlineAppearance.selected.iconColor = color
inlineAppearance.selected.titleTextAttributes = [
.foregroundColor: color
]
let tabAppearance = UITabBarAppearance()
tabAppearance.compactInlineLayoutAppearance = inlineAppearance
tabAppearance.inlineLayoutAppearance = inlineAppearance
tabAppearance.stackedLayoutAppearance = stackedAppearance
UITabBar.appearance().standardAppearance = tabAppearance
UITabBar.appearance().scrollEdgeAppearance = tabAppearance
Summary
In iOS 18, the UICollectionViewDelegate method
collectionView(_:targetIndexPathForMoveOfItemFromOriginalIndexPath:atCurrentIndexPath:toProposedIndexPath:)
is not being called when moving items in a UICollectionView. This method works as expected in iOS 17.5 and earlier versions.
Steps to Reproduce
Create a UICollectionView with drag and drop enabled.
Implement the UICollectionViewDelegate method:
func collectionView(_ collectionView: UICollectionView, targetIndexPathForMoveOfItemFromOriginalIndexPath originalIndexPath: IndexPath, atCurrentIndexPath currentIndexPath: IndexPath, toProposedIndexPath proposedIndexPath: IndexPath) -> IndexPath {
print("🐸 Move")
return proposedIndexPath
}
Run the app on iOS 18.
Attempt to drag and drop items within the collection view.
Expected Behavior
The method should be called during the drag and drop operation, and "🐸 Move" should be printed to the console.
Actual Behavior
The method is not called, and nothing is printed to the console. The drag and drop operation still occurs, but without invoking this delegate method.
Configuration
iOS Version: 18
Xcode Version: Xcode 16.0.0
In iOS 26, the Slider control no longer respects the step parameter. For example,
import SwiftUI
struct ContentView: View {
@State private var sliderValue: CGFloat = 16
var body: some View {
Slider(
value: $sliderValue,
in: 0...100,
step: 5,
onEditingChanged: { editing in
print(sliderValue)
}
)
}
}
In iOS 18, this prints values like 5, 35, 60, 95, etc. In iOS 26.0 (release version), this prints floats that are not rounded to the nearest 5, and the slider does not snap to values ending in 5.

I'm trying to apply a tinted glass effect to toolbar buttons in iOS 26, similar to what was shown in the WWDC25 videos, but none of the approaches I've tried produce the translucent tinted glass effect.
My code structure:
.toolbar {
ToolbarItem(placement: .navigationBarTrailing) {
TrailingToolbarContent(
selectedTab: $selectedTab,
showingAddBeneficiary: $showingAddBeneficiary
)
}
}
private struct TrailingToolbarContent: View {
@Binding var selectedTab: Int
@Binding var showingAddBeneficiary: Bool
@EnvironmentObject private var settingsViewModel: SettingsViewModel
var body: some View {
switch selectedTab {
case 1:
if #available(iOS 26.0, *) {
Button(action: { showingAddBeneficiary = true }) {
Image(systemName: "plus")
}
// What I've tried:
// .tint(Color("accentPrimary")) // Only changes icon color
// .glassEffect(.regular.tint(Color("accentPrimary"))) // No effect
// .buttonStyle(.glass).tint(Color("accentPrimary")) // No tint, but orange background
// .buttonStyle(.borderedProminent).tint(Color("accentPrimary")) // Works but seems opaque, not glass
}
// ... other cases
}
}
}
What's the correct way to achieve tinted glass effects on toolbar buttons?

On an iPad running iOS26, there is an issue with the numberPad keyboard
I have a UITextField with a keyboard type of .numberPad
When I first tap in the field, a new number pad with just numbers (similar to the one that shows up on iPhone) shows up.
When I tap again in the field, that number pad goes away.
When I tap in the field again, the full keyboard with numbers etc shows up (this is the one that used to always show up pre-iOS26)

I'm being faced with an issue when using SwiftUI's WebView on iOS 26. In many websites, the top/bottom content is unaccessible due to being under the app's toolbars. It feels like the WebView doesn't really understand the safe areas where it's being shown, because the content should start right below the navigation bar, and only when the user scrolls down, the content should move under the bar (but it's always reachable if the users scroll back up).
Here's a demo of the issue:
Here's a 'fix' by ensuring that the content of the WebView never leaves its bounds. But as you can see, it feels out of place on iOS 26 (would be fine on previous OS versions if you had a fully opaque toolbar):
Code:
struct ContentView: View {
var body: some View {
NavigationStack {
WebView(url: URL(string: "https://apple.com")).toolbar {
ToolbarItem(placement: .primaryAction) {
Button("Top content covered, unaccessible.") {}
}
}
}
}
}
Does anyone know if there's a way to fix it using some sort of view modifier combination or it's just broken as-is?
Hi!
We've recently done a big migration to Swift 6 language mode in our app and are now getting reports of crashes occurring due to closures in our SwiftUI code (most often the view builder in ForEach) not running on the main queue but instead running on the queue com.apple.SwiftUI.AsyncRenderer. One example of a call stack (ScheduleListView is our view that is in Swift 6 mode):
Thread 16
#0 (null) in _dispatch_assert_queue_fail ()
#1 (null) in dispatch_assert_queue$V2.cold.1 ()
#2 (null) in dispatch_assert_queue ()
#3 (null) in swift_task_isCurrentExecutorWithFlagsImpl(swift::SerialExecutorRef, swift::swift_task_is_current_executor_flag) ()
#4 (null) in closure #2 in closure #1 in closure #1 in ScheduleListView.body.getter ()
#5 (null) in closure #1 in ForEachState.item(at:offset:) ()
#6 (null) in partial apply for closure #1 in ForEachState.item(at:offset:) ()
#8 (null) in partial apply for closure #1 in _withObservation<A>(do:) ()
....
(We have many other crashes with similar crash reports but in other views)
Has anybody else run into something similar? Is there anything (other than simply reverting to Swift 5 mode again) that we can do to fix or at least reduce the amount of crashes? We're having a hard time finding anything out of the ordinary that we're doing in our views.
Regards

Try this simple code:
import SwiftUI
import StoreKit
struct ReviewView: View {
@Environment(\.requestReview) var requestReview
var body: some View {
Button("Leave a review") {
requestReview()
}
}
}
When the Review Alert shows, the "Not Now" button is disabled for some reason!? It was always tappable in all iOS versions that I remember. And there is no way to opt out, unless the user taps on the stars first. Is it a bug or a feature?
Thanks for looking into it!
I've discovered an issue with using iOS 16's Transferable drag-and-drop APIs for SwiftUI. The dropDestination modifier does not work when applied to a subview of a List.
This code below will not work, unless you replace the List with a VStack or any other container (which, of course, removes all list-specific rendering).
The draggable modifier will still work and the item will drag, but the dropDestination view won't react to it and neither closure will be called.
struct MyView: View {
var body: some View {
List {
Section {
Text("drag this title")
.font(.largeTitle)
.draggable("a title")
}
Section {
Color.pink
.frame(width: 400, height: 400)
.dropDestination(for: String.self) { receivedTitles, location in
true
} isTargeted: {
print($0)
}
}
}
}
}
Has anyone encountered this bug and perhaps found a workaround?
Hello, im getting popping / crackling sounds from my Macbook Pro (M4 2024) speakers.
This happens when you do many certain tasks like click buttons or toggling switches when xcode has a simulator open and any background audio is playing, like spotify.
The speakers go crazy especially when starting the simulator in xcode with music in background.
Ive tried:
Using blackhole, and changing audio output in the simulator app
Deleting both .plist files form preferences file.
"coreaudiod" trick in terminal
restarting many times
different xcode versions and simulators and swift files
Nothing has worked. Any help?
