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.

I opened a feedback ticket (FB16508762) but maybe someone in the community already found a workaround while the feedback reaches the maintainers.
When I put a Button inside a ScrollView, the tap animation stops working reliably and works only when the user taps and holds the button for a short time. The reasons, I believe is related to the fact that isPressed of configuration does not change and the default button styles use it to animate the tap.
import SwiftUI
struct DebuggingButtonStyle: ButtonStyle {
func makeBody(configuration: Configuration) -> some View {
configuration.label
.onChange(of: configuration.isPressed, { oldValue, newValue in
print("Is pressed: \(oldValue) -> \(newValue)")
})
}
}
struct ContentView: View {
var body: some View {
VStack {
Text("Buttons inside scroll view respond to taps as expected, however isPessed value of the configuration do not change unless the user press and hold it. Try to press the promiment button quickly or use the debug button and observe the console log.")
ScrollView {
VStack {
Button("Button Inside ScrollView") {
print("Button tapped")
}
.buttonStyle(.borderedProminent)
Button("Button Inside ScrollView (printing isPressed)") {
print("Button tapped")
}
.buttonStyle(DebuggingButtonStyle())
}
}
.border(FillShapeStyle(), width: 2)
Spacer()
Text("For reference, here is a button outside of a ScrollView. Tap the promiment button to observe how the button is expected to animate in respnse to a press.")
VStack {
Button("Button Outside ScrollView") {
print("Button tapped")
}
.buttonStyle(.borderedProminent)
Button("Button Outside ScrollView (printing isPressed)") {
print("Button tapped")
}
.buttonStyle(DebuggingButtonStyle())
}
}
.padding()
}
}
My app uses the SwiftUI Map control to display annotations. When annotations contain buttons AND the map has an .onTapGesture modifier, annotation button taps aren’t always recognized.
Given the following ContentView, run it on an iOS device or simulator. Tap the buttons. Since iOS 18.0, some of the buttons won't respond to tap. I've also tried using the onTapGesture instead of a button, and that shows the same issue.
This was not a problem under iOS 17.x: it has only shown up for my users since updating to iOS 18. Additionally, this issue does not occur when running on either macOS 15.0 or visionOS 2.0 when running in "designed for iPad" mode.
Note that there was previously a tap issue on VisionOS 1.x (designed for iPad), where no tap gestures were received by annotations. I'm curious if this issue could be related.
I have filed a report in Feedback Assistant (FB15273909).

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!

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?

Hello there!
I wanted to give a native scrolling mechanism for the Swift Charts Graph a try and experiment a bit if the scenario that we try to achieve might be possible, but it seems that the Swift Charts scrolling performance is very poor.
The graph was created as follows:
X-axis is created based on a date range,
Y-axis is created based on an integer values between moreless 0-320 value.
the graph is scrollable horizontally only (x-axis),
The time range (x-axis) for the scrolling content was set to one year from now date (so the user can scroll one year into the past as a minimum visible date (.chartXScale).
The X-axis shows 3 hours of data per screen width (.chartXVisibleDomain).
The data points for the graph are generated once when screen is about to appear so that the Charts engine can use it (no lazy loading implemented yet).
The line data points (LineMark views) consist of 2880 data points distributed every 5 minutes which simulates - two days of continuous data stream that we want to present. The rest of the graph displays no data at all.
The performance result:
The graph on the initial loading phase is frozen for about 10-15 seconds until the data appears on the graph.
Scrolling is very laggy - the CPU usage is 100% and is unacceptable for the end users.
If we show no data at all on the graph (so no LineMark views are created at all) - the result is similar - the empty graph scrolling is also very laggy.
Below I am sharing a test code:
@main
struct ChartsTestApp: App {
var body: some Scene {
WindowGroup {
ContentView()
Spacer()
}
}
}
struct LineDataPoint: Identifiable, Equatable {
var id: Int
let date: Date
let value: Int
}
actor TestData {
func generate(startDate: Date) async -> [LineDataPoint] {
var values: [LineDataPoint] = []
for i in 0..<(1440 * 2) {
values.append(
LineDataPoint(
id: i,
date: startDate.addingTimeInterval(
TimeInterval(60 * 5 * i) // Every 5 minutes
),
value: Int.random(in: 1...100)
)
)
}
return values
}
}
struct ContentView: View {
var startDate: Date {
return endDate.addingTimeInterval(-3600*24*30*12) // one year into the past from now
}
let endDate = Date()
@State var dataPoints: [LineDataPoint] = []
var body: some View {
Chart {
ForEach(dataPoints) { item in
LineMark(
x: .value("Date", item.date),
y: .value("Value", item.value),
series: .value("Series", "Test")
)
}
}
.frame(height: 200)
.chartScrollableAxes(.horizontal)
.chartYAxis(.hidden)
.chartXScale(domain: startDate...endDate) // one year possibility to scroll back
.chartXVisibleDomain(length: 3600 * 3) // 3 hours visible on screen
.onAppear {
Task {
dataPoints = await TestData().generate(startDate: startDate)
}
}
}
}
I would be grateful for any insights or suggestions on how to improve it or if it's planned to be improved in the future.
Currently, I use UIKit CollectionView where we split the graph into smaller chunks of the graph and we present the SwiftUI Chart content in the cells, so we use the scrolling offered there. I wonder if it's possible to use native SwiftUI for such a scenario so that later on we could also implement some kind of lazy loading of the data as the user scrolls into the past.
Hello,
I'm using LongPressGesture to provide haptic & color change feedback on a long press action. This fails to call the .updating(_:body:) method on every iOS 18.0 beta. It works fine on iOS 17.
The following code, taken directly from Apple's documentation illustrates the problem. The .updating() closure is never called, while the .onEnded() closure is called correctly. Instead of a gradual color transition the example code generates a delayed sharp switch from Red to Blue, preventing interactive user feedback.
struct LongPressGestureView: View {
@GestureState private var isDetectingLongPress = false
@State private var completedLongPress = false
var longPress: some Gesture {
LongPressGesture(minimumDuration: 3)
.updating($isDetectingLongPress) { currentState, gestureState,
transaction in
gestureState = currentState
transaction.animation = Animation.easeIn(duration: 2.0)
}
.onEnded { finished in
self.completedLongPress = finished
}
}
var body: some View {
Circle()
.fill(self.isDetectingLongPress ?
Color.red :
(self.completedLongPress ? Color.green : Color.blue))
.frame(width: 100, height: 100, alignment: .center)
.gesture(longPress)
}
}
Can anyone share tips on a workaround or potential fix application-side?

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.
I have installed the iOS 26 Beta on my device and conducted a comprehensive functionality test of my iOS application, which I designed and developed. The application includes a feature that allows users to share images directly to X (formerly Twitter) and Facebook.
During testing, I encountered an issue where the icons for X (formerly Twitter) and Facebook do not appear in the share dialog, despite both apps being installed on the device. This issue prevents users from sharing images to these platforms directly from the app.
Steps to Reproduce:
1.Install iOS 26 Beta on a compatible device.
2.Ensure that both the X (formerly Twitter) and Facebook apps are installed and logged in on the device.
3.Open the iOS application and navigate to the image sharing feature.
4.Attempt to share an image using the share dialog.
5.Observe that the icons for X (formerly Twitter) and Facebook are missing from the share options.
Expected Behavior:
The share dialog should display icons for X (formerly Twitter) and Facebook, allowing users to share images directly to these platforms.
Actual Behavior:
The icons for X (formerly Twitter) and Facebook do not appear in the share dialog, preventing direct sharing to these platforms.
Code Implementation:
I have not implemented any code to exclude X (formerly Twitter) and Facebook from the share options. Below is the relevant code for controlling the share screen:
let activityViewController = UIActivityViewController(activityItems: activityItems, applicationActivities: applicationActivities)
let excludedTypes = [
UIActivity.ActivityType.assignToContact,
UIActivity.ActivityType.print,
]
activityViewController.excludedActivityTypes = excludedTypes
activityViewController.completionWithItemsHandler = completion
self.present(activityViewController, animated: true, completion: nil)
As shown in the implementation, there is no exclusion of X (formerly Twitter) and Facebook, yet their icons do not appear in the share dialog.
With the introduction of the new matchedTransitionSource from iOS 18, we can apply a zoom transition in the navigation view using .navigationTransition(.zoom) This works well for zoom animations.
However, when I try to apply a matched geometry effect to views that are similar in the source and destination views, the zoom transition works, but those views don't transition seamlessly as they do with a matched geometry effect.
Is it possible to still use matched geometry for subviews of the source and destination views along with the new navigationTransition?
Here’s a little demo that reproduces this behaviour:
struct ContentView: View {
let colors: [[Color]] = [
[.red, .blue, .green],
[.yellow, .purple, .brown],
[.cyan, .gray]
]
@Namespace() var namespace
var body: some View {
NavigationStack {
Grid(horizontalSpacing: 50, verticalSpacing: 50) {
ForEach(colors, id: \.hashValue) { rowColors in
GridRow {
ForEach(rowColors, id: \.self) { color in
NavigationLink {
DetailView(color: color, namespace: namespace)
.navigationTransition(
.zoom(
sourceID: color,
in: namespace
)
)
.edgesIgnoringSafeArea(.all)
} label: {
ZStack {
RoundedRectangle(cornerRadius: 5)
.foregroundStyle(color)
.frame(width: 48, height: 48)
Image(systemName: "star.fill")
.foregroundStyle(Material.bar)
.matchedGeometryEffect(id: color,
in: namespace,
properties: .frame, isSource: false)
}
}
.matchedTransitionSource(id: color, in: namespace)
}
}
}
}
}
}
}
struct DetailView: View {
var color: Color
let namespace: Namespace.ID
var body: some View {
ZStack {
color
Image(systemName: "star.fill")
.resizable()
.foregroundStyle(Material.bar)
.matchedGeometryEffect(id: color,
in: namespace,
properties: .frame, isSource: false)
.frame(width: 100, height: 100)
}
.navigationBarHidden(false)
}
}

Hello Apple Developer Community: I have a problem with the fullscreencover. I can see the Things, that shouldn’t be visible behind it.
I’m currently developing with iOS 26 and only there it happens.
I hope you can help me :)
Have a nice day
I'm trying to do something so seemingly basic, yet I can't get it to work and I'm flummoxed.
In a basic, vanilla SwiftUI app for tvOS, embed a single Text element with a very long string (hundreds of lines) in it:
struct ContentView: View {
var body: some View {
ScrollView(.vertical) {
Text(veryLargeString)
.focusable()
}
}
}
Then fire up the app on tvOS, and it will not scroll. No matter what I do. Pressing arrow keys, swiping fast with my thumb, and nothing. It will not move. Ironically, in the Xcode SwiftUI Preview window—it does scroll, so that's always a fun tease.
What I do know is that the focus engine is throwing a few errors, so it's leading me to believe the issue is with how I have the focusable element attached. I'm using a combination of -UIFocusLoggingEnabled YES as well as listening for UIFocusSystem.movementDidFailNotification.
Unfortunately since this is SwiftUI, the notification failure and debugging logs aren't really all that actionable. Help appreciated!
We're seeing a sharp uptick in BaseBoard/FrontBoardServices crashes since we migrated from UIApplicationDelegate to UIWindowSceneDelegate. Having exhausted everything on my end short of reverse engineering BaseBoard or making changes without being able to know if they work, I need help. I think all I need to get unstuck is an answer to these questions, if possible:
What does -[BSSettings initWithSettings:] enumerate over? If I know what's being enumerated, I'll know what to look for in our app.
What triggers FrontBoardServices to do this update? If I can reproduce the crash--or at least better understand when it may happen--I will be better able to fix it
Here's two similar stack traces:
App_(iOS)-crashreport-07-30-2025_1040-0600-redacted.crash
App_(iOS)-crashreport-07-30-2025_1045-0600-redacted.crash
Since these are private trameworks, there is no documentation or information on their behavior that I can find.
There are other forum posts regarding this crash, on here and on other sites. However, I did not find any that shed any insight on the cause or conditions of the crash. Additionally, this is on iPhone, not macOS, and not iPad. This post is different, because I'm asking specific questions that can be answered by someone with familiarity on how these internal frameworks work. I'm not asking for help debugging my application, though I'd gladly take any suggestions/tips!
Here's the long version, in case anyone finds it useful:
In our application, we have seen a sharp rise in crashes in BaseBoard and FrontBoardServices, which are internal iOS frameworks, since we migrated our app to use UIWindowSceneDelegate. We were using exclusively UIApplicationDelegate before. The stack traces haven't proven very useful yet, because we haven't been able to reproduce the crashes ourselves.
Upon searching online, we have learned that Baseboard/Frontsoardservices are probably copying scene settings upon something in the scene changing. Based on our crash reports, we know that most of our users are on an iPhone, not an iPad or macOS, so we can rule out split screen or window resizing. Our app is locked to portrait as well, so we can also rule out orientation changes. And considering the stack trace is in the middle of an objc_retain_x2 call, which is itself inside of a collection enumeration, we are assuming that whatever is being enumerated probably was changed or deallocated during enumeration. Sometimes it's objc_retain_x2, and sometimes it's a release call. And sometimes it's a completely different stack trace, but still within BaseBoard/FrontBoardServices. I suspect these all share the same cause.
Because it's thread 0 that crashed, we know that BaseBoard/FrontBoardServices were running on the main thread, which means that for this crash to occur, something might be changing on a background thread. This is what leads me to suspect a race condition.
There are many places in our app where we accidentally update the UI from a background thread. We've fixed many of them, but I'm sure there are more. Our app is large. Because of this, I think background UI are the most likely cause. However, since I can't reproduce the crash, and because none of our stack traces clearly show UI updates happening on another thread at the same time, I am not certain.
And here's the stack trace inline, in case the attachments expire or search engines can't read them:

I'm running into a persistent problem with the iOS 18.5 simulator in Xcode 26 beta 2. I have built a very simple test app with a storyboard that includes only a toolbar added to the ViewController scene in the storyboard. The test app runs fine in iOS 26 simulators.When I try to run it in the iOS 18.5 simulator for iPhone Pro or iPad (16), it fails while unarchiving the storyboard (as far as I can tell) with this error message in the Xcode console:
*** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView because no class named TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)'

I'd love a simple workaround for this.

I noticed that trying to access safeAreaInsets from the active window causes an infinite run loop.
This issue appeared after updating to Beta 3.
Here’s an example of the code:
extension UIDevice {
var safeAreaInsets: UIEdgeInsets {
guard let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene,
let window = windowScene.windows.first(where: { $0.isKeyWindow }) else {
return .zero
}
return window.safeAreaInsets
}
}
The return doesn’t happen because it ends up in some kind of recursion.
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
Hi,
I'm seeing an issue in iOS 26 beta related to UINavigationBar rendering in landscape.
When a background color is set for the navigation bar and the device is rotated to landscape, an unexpected gap appears above the navigation bar.
This also happens in the official sample project provided in Apple’s documentation:
https://developer.apple.com/documentation/uikit/customizing-your-app-s-navigation-bar
Is this a bug in the beta, or is there a workaround to avoid this behavior?
Thanks in advance!
Why is the UIKeyboard implementation still holding a reference to this UITextField, thus keeping it from being deallocated?
The memory debugger shows:
UIKeyboardImpl -> UIKBAutofillController -> NSMutableDictionary -> NSMutable...(Storage) -> UITextField
Any idea what's going on there?
