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?

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.
The following WatchOs App example is very short, but already not functioning as it is expected, when using Digital Crown (full code):
import SwiftUI
struct ContentView: View {
let array = ["One","Two","Three","Four"]
@State var selection = "One"
var body: some View {
Picker("Array", selection: $selection) {
ForEach(array, id: \.self) {
Text($0)
}
}
}
}
The following 2 errors are thrown, when using Digital Crown for scrolling:
ScrollView contentOffset binding has been read; this will cause grossly inefficient view performance as the ScrollView's content will be updated whenever its contentOffset changes. Read the contentOffset binding in a view that is not parented between the creator of the binding and the ScrollView to avoid this.
Error: Error Domain=NSOSStatusErrorDomain Code=-536870187 "(null)"
Any help appreciated. Thanks a lot.
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?
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?

We have been having problems with our app clip not working when sharing through iMessage. The app and app clip are published and work correctly when scanning a QR code that points to the URL: https://www.coderus.com/locations?loc=1 however if this same URL is shared through the iMessage app, a link to the website displays and not the app clip card.
We have confirmed that:
AASA file is available and has the type application/json
Both devices are above iOS 14
Both devices are in each other's contacts
The website has the meta tag for the smart app clip banner
The website has a meta tag for the og:image
Launch experiences have been configured on AppStoreConnect - as said before, the QR codes work correctly
The link leads to a 404 page, I wasn't sure if there needs to be an actual page that the link points to as app clips seem to work fine without when scanning the QR code through the camera app.
Prior to iOS 26, it was possible to design an inputAccessoryView(Controller) that would integrate seamlessly with the system keyboard, by which I mean appearing as a natural extension of the system keyboard. For example, using CYRKeyboardButton https://github.com/tmcintos/CYRKeyboardButton.
To date, I have successfully used this to provide an enhanced numeric key row within my apps, which is a distinguishing feature of these apps. It took a lot of engineering and testing effort to perfect this design. However, with iOS 26 the design is completely broken due to the system keyboard UI change, which makes it impossible to display an inputAccessoryView seamlessly along the top of the system keyboard (see attached screenshots).
In my opinion, it is just plain reckless for Apple to make these kinds of trivial UI changes, which break existing app designs without adding any significant value to the user experience.
iOS ≤ 18.x:
iOS 26 beta:
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.

Using the iOS 26 beta simulator, I am experiencing a crash using the QLPreviewController. This is easily reproduced using a small sample app and a sample excel file in the bundle. It does work in prior Xcode 16.4 and simulators (18.5). I didn't find any mention of this in Xcode 26 or iOS 26 release notes but I could have missed something. I don't have a spare device to update to iOS 26 and try on a real device so it may just be a simulator issue? Any feedback would be helpful. Thanks.

When you touch down on a button in a scroll view, you can cancel the tap by scrolling. In SwiftUI, this works correctly when the scroll view is not inside a dismissible sheet.
However, if the scroll view is inside a sheet that can be dismissed with a drag gesture, scrolling does not cancel the button touch, and after scrolling, the button tap is activated.
This happens whether the modal is presented from SwiftUI using the sheet modifier, or wrapped in a UIHostingController and presented from UIKit.
This is a huge usability issue for modals with scrollable content that have buttons inside of them.
Video of behavior: https://youtube.com/shorts/w6eqsmTrYiU
Easily reproducible with this code:
import SwiftUI
struct ContentView: View {
@State private var isPresentingSheet = false
var body: some View {
ScrollView {
LazyVStack {
ForEach(0..<100, id: \.self) { index in
Button {
isPresentingSheet = true
} label: {
Text("Button \(index)")
.padding(.horizontal)
.padding(.vertical, 5)
.frame(maxWidth: .infinity, alignment: .leading)
}
}
}
.padding()
}
.sheet(isPresented: $isPresentingSheet) {
ContentView()
}
}
}
We are trying to implement live caller id lookup, there is lack of documentation and we would like to understand few blockers that we have:
Based on this documentation page: https://developer.apple.com/documentation/identitylookup/setting-up-the-http-endpoints-for-live-caller-id-lookup:
What exactly should accept/return these endpoints?. There is no detailed description of the response/request schema for any endpoint.
What are the usage scenarios of the "/key" method? If it is possible to get a more detailed explanation regarding Evaluation Key usage as it is not clear from the available documentation.
Based on this step by step implementation description: https://github.com/apple/live-caller-id-lookup-example/blob/main/Sources/PIRService/PIRService.docc/Authentication.md:
The 6th step: "Authentication server returns the list of public keys (potentially through a proxy)". What is the endpoint path and response format expected by the iOS system? This step refers to calling the '/config' endpoint ?
The 8th step: "Authentication server verifies the User Token and returns the public key that is associated with the User Tier. ..." What is the the endpoint path and request/response format expected by the iOS system?
The 9th step: "The system constructs a Privacy Pass token request using the specific public key. The token request is sent along with the User Token to the authentication server". What is the request/response format expected by the iOS system?
The 11th step: "When a PIR request is made, the system attached an unused Privacy Pass token to the request. The PIR node can use the public key to verify that the token is valid and that assures that the request is authorized". What is the request/response format expected by the iOS system?
On executing refreshPIRParameters fom app I get this error:
LiveCallerIDLookupManager.shared.refreshPIRParameters(forExtensionWithIdentifier: LiveCallerIdExtensionName)
Unable to query status due to errors: server error (Access DeniedAccess DeniedYou don't have permission to access "http://www.example.com/config" on this server.Reference #18.cdde00d4.1738074526.3a38870https://errors.edgesuite.net/18.cdde00d4.1738074526.3a38870)

When building with iOS 26 SDK beta 5 (23A5308f), onTapGesture is no longer being triggered on Map views. This appears to be a regression in beta 5 specifically, as this issue was not present in beta 4.
How to reproduce
Code
The following code demonstrates the issue, as seen in the videos below.
import MapKit
import SwiftUI
struct ContentView: View {
@State private var location = CGPoint.zero
var body: some View {
Map()
.onTapGesture { location in
self.location = location
}
.safeAreaInset(edge: .bottom) {
VStack(alignment: .center) {
Text("iOS \(UIDevice.current.systemVersion)")
.font(.largeTitle)
Text("Tapped Location")
Text("\(location.x), \(location.y)")
}
.frame(maxWidth: .infinity, alignment: .center)
.background(.background)
}
}
}
Demo
The gifs below show the behavior in iOS 18.5 (in which the tap gestures are recognized and tapped coordinate is displayed in the safe area inset) and iOS 26 beta 5 (in which the tap gestures have no effect):
iOS 18
iOS 26
Next steps?
Is there a recommended workaround for this issue?
The sample code provided in "Building a document-based app with SwiftUI" (https://developer.apple.com/documentation/swiftui/building-a-document-based-app-with-swiftui) does not work as expected.
The DocumentGroup/StoryView toolbar does not appear for documents opened in the App.
By removing the DocumentGroupLaunchScene block from the App the toolbar does appear and works as expected - but of course the App's DocumentGroupLaunchScene customizations are lost.
I've tested this on 18.0 devices, as well as production 18.0 and 18.1 beta 6 simulators.
If I modify the StoryView by wrapping the content in a NavigationStack I can make some progress - but the results are unstable and hard to pin down - with this change the first time a document is opened in the WritingApp the toolbar appears as expected. When opening a document subsequently the toolbar is corrupted.
Please is this a bug or is there a good example of incorporate both DocumentGroupLaunchScene customizations at the App level and retina the toolbar in documents presented via DocumentGroup?

Using an App Clip link encoded into a QR Code shows an error when scanning the encoded QR Code on an iPhone or iPad.
After being scanned, the App Clip's banner is visible, but a message says: "App Clip Unavailable".
Accessing the same App Clip URL via Safari works as expected.
I've filed a feedback with more details and screenshots of the issue here: FB17891015
Thanks!
Summary
As presented in the SwiftUI WWDC video, the new tabViewBottomAccessory should allow for unique contents for .inline. This is what was presented as being used for the Apple Music miniplayer. However, the functionality seems to be either missing or unintuitive. As seen in the photos attached, not only does .inline functionality not seem to do anything, but the inline accessory also has misaligned elements that cannot be fixed by conditionally modifying the contents.
Build Target
iOS 26.0
Details
This problem recurs on physical devices, simulators, and Xcode previews.
Here is a view I've constructed for use as a tabViewBottomAccessory:
struct FitnessToolbarAccessory: View {
@Environment(\.tabViewBottomAccessoryPlacement) var placement
var body: some View {
if (placement == .inline) {
Text("hello")
} else {
HStack {
HStack {
Image(systemName: "dumbbell.fill")
VStack(alignment: .leading) {
Text("Active Workout")
Text("Push Day - Chest")
.font(.system(size: 13))
}
Spacer()
Image(systemName: "pause.fill")
}
.padding()
}
}
}
}
Here is the result, working as expected in expanded mode:
And here is the result in inline mode after minimizing the tabViewBottomAccessory:
The content of this inline accessory is clearly incorrect, as it was specified to contain a Text view containing "hello". Additionally, the contents seem to have some incorrect alignment. This occurs regardless of the contents of the accessory, even plain text.
Hi everyone,
I've come across an issue on iOS that seems to affect many apps. Here's what happens:
A user logs in with correct credentials and proceeds to the OTP verification screen as part of multi factor authentication.
iOS presents the system password save prompt ("Would you like to save this password?").
Without selecting an option on this prompt, the user backgrounds the app (e.g., to check their email for the OTP).
Upon returning to the app, the keyboard becomes completely inaccessible on the OTP screen or any other screen.
From my testing, this behavior appears to be an OS-level bug, as it occurs consistently across various apps. Has anyone else encountered this? Any known workarounds or updates from Apple on this behavior would be greatly appreciated!
Thanks!

Hello,
I'm experiencing a navigation bar positioning issue with my UIKit iPad app on iPadOS 26 (23A340) using Xcode 26 (17A321).
The navigation bar positions under the status bar initially, and after orientation changes to landscape, it positions incorrectly below its expected location. This occurs on both real device (iPad mini A17 Pro) and simulator. My app uses UIKit + Storyboard with a Root Navigation Controller.
A stack overflow post has reproduce the bug event if it's not in the same configuration: https://stackoverflow.com/questions/79752945/xcode-26-beta-6-ipados-26-statusbar-overlaps-with-navigationbar-after-presen
I have checked all safe areas and tried changing some constraints, but nothing works.
Have you encountered this bug before, or do you need additional information to investigate this issue?
When I dismiss a view presented with .navigationTransition(.zoom), the source view gets a weird background (black or white depending on the appearance) for a couple of seconds, and then it disappears.
Here’s a simple code example.
import SwiftUI
struct NavigationTransition: View {
@Namespace private var namespace
@State private var isSecondViewPresented = false
var body: some View {
NavigationStack {
ZStack {
DetailView(namespace: namespace)
.onTapGesture {
isSecondViewPresented = true
}
}
.fullScreenCover(isPresented: $isSecondViewPresented) {
SecondView()
.navigationTransition(.zoom(sourceID: "world", in: namespace))
}
}
}
}
struct DetailView: View {
var namespace: Namespace.ID
var body: some View {
ZStack {
Color.blue
Text("Hello World!")
.foregroundStyle(.white)
.matchedTransitionSource(id: "world", in: namespace)
}
.ignoresSafeArea()
}
}
struct SecondView: View {
var body: some View {
ZStack {
Color.green
Image(systemName: "globe")
.foregroundStyle(Color.red)
}
.ignoresSafeArea()
}
}
#Preview {
NavigationTransition()
}
Right now, the traffic light buttons overlapped on my iPad app top corner on windows mode (full screen is fine).
How do I properly design my app to avoid the traffic light buttons? Detect that it is iPadOS 26?
