Does causing a swiftui view refresh via modifying observed properties while an alert is visible allowed?
I am seeing a warning
'Presenting view controller <SwiftUI.PlatformAlertController> from detached view controller is not supported, and may result in incorrect safe area insets and a corrupt root presentation. Make sure <SwiftUI.PlatformAlertController> is in the view hierarchy before presenting from it. Will become a hard exception in a future release.'
and the warning
'Attempt to present <SwiftUI.PlatformAlertController> on (from ) while a presentation is in progress'.
The second warning occurs more often.

Hello everyone,
I am currently working on a project that requires me to programmatically manage keyboard layouts on both iOS and macOS devices. I'm looking for a comprehensive list of KeyboardLayout ID values for all the native keyboard layouts available in both iOS and macOS. While I can extract some of this information from the /System/Library/Keyboard Layouts/ directory on macOS, I cannot extract all without adding every keyboard layout active, having a complete and pre-compiled list would be immensely helpful.
Does anyone here have such a list or know where I might find one? Any guidance on this matter would be greatly appreciated.
Thank you in advance for your assistance!

Hi,
I have noticed a major uptick in crash reports, ever since I updated my app for macOS Sequoia. All of them have to do with NSOutlineView, and they all have a similar internal API in the crash log, which shows that the issue is something to do with the framework. They all have references to NSConcreteMapTable and _TtCs12_SwiftObject isEqual.
The issue isn't reproducible, but it's reported by many different users, all on macOS15+, and it was never an issue with macOS14 or below, so I'm not sure what to do about it.
Here's a couple of examples of the new crash reports:

I just created a Feedback FB15625970. Please let me know if this is a known issue, and/or if there's any ideas out there on how I can do to avoid this. It's causing a lot of instability in my app, that wasn't there before macOS15, so something changed in the internal APIs, and hopefully there's a way to work around it.
Our Apple TV provides UIImages with renderingMode forced to .alwaysTemplate (the images are also configured with "Render As" to "Template image" in the Asset catalog) to UIActions as UIMenuElement when building a UICollectionView UIContextMenuConfiguration.
Problem: these images are not displayed with vibrancy effect by the system.
The issue does not occur with system images (SVG from SF Catalog).
Here is a screenshot showing the issue with custom images ("Trailer" and "Remove from favourites"):
I don't know the underlying implementation of the context menu items image but UIImageView already implements the tintColorDidChange() method and the vibrancy should work if the UIImage is rendered as template.
According to my tests, the vibrancy is correctly applied when using Symbols sets instead of Images sets but I understand that custom images rendered as template should support it as-well, shouldn't they?
When I toggle a panel like navigationsidebar, I get a message in the console. I guess it's not a big issue, but is there a way to fix this message? because it appears in every project.

Hello team i notice that we have a problem in our app that every time the user opens a Textfield the app freezes when the keyboard appears, this behavior was tracked down and it's a UI breaking design on a UIView
[this view it's expandable and is original size is 80]
[when it gets expanded 206.33]
this is the view code I change the colors to easy check the other's views created inside
private lazy var sharedUIPlaybackView: UIView = {
let containerView = UIView().withAutoLayout()
let propertySearchCriteria = PropertySearchCriteriaBuilder(hotelSearchParameters: viewModel.hotelSearchParameters).criteria
var swiftUIView: SwiftUIView<LodgingPlaybackWrapper>! = nil
swiftUIView = SwiftUIView(
LodgingPlaybackWrapper(propertySearchCriteria: propertySearchCriteria,
playbackUpdateNotificationSender: playbackUpdateNotificationSender,
componentHandler: { [weak self] componentId in
self?.componentReady(componentId)
}),
viewDidLayoutSubviewsCallback: { [weak self] in
let extraPadding = self?.playbackViewExtraPadding ?? Spacing.spacing8x
let newHeight = swiftUIView.frame.size.height + extraPadding
// if newHeight != self?.sharedUIPlaybackViewHeightConstraint?.constant {
// self?.sharedUIPlaybackViewHeightConstraint?.constant = 206.33
// }else {
// self?.sharedUIPlaybackViewHeightConstraint?.constant = 80
// }
}
).withAutoLayout().withAccessibilityIdentifier("test")
// sharedUIPlaybackViewHeightConstraint = containerView.heightAnchor.constraint(equalToConstant: 0)
// sharedUIPlaybackViewHeightConstraint?.isActive = true
containerView.backgroundColor = .blue
swiftUIView.backgroundColor = .red
containerView.addSubview(swiftUIView)
containerView.addConstraints([
swiftUIView.topAnchor.constraint(equalTo: containerView.topAnchor, constant: playbackViewTopConstant),
swiftUIView.leadingAnchor.constraint(equalTo: containerView.leadingAnchor, constant: Spacing.spacing4x),
swiftUIView.trailingAnchor.constraint(equalTo: containerView.trailingAnchor, constant: -Spacing.spacing4x),
swiftUIView.bottomAnchor.constraint(equalTo: containerView.bottomAnchor, constant: -Spacing.spacing3x),
swiftUIView.heightAnchor.constraint(equalToConstant: 206.33)
])
return containerView
}()
old devs created this function viewDidLayoutSubviewsCallback to connect user interaction on the wrapper and used on UIKit.
this is the part where the math on the function gets weird and messed up the code by crashing the view
viewDidLayoutSubviewsCallback: { [weak self] in
let extraPadding = self?.playbackViewExtraPadding ?? Spacing.spacing8x
let newHeight = swiftUIView.frame.size.height + extraPadding
if newHeight != self?.sharedUIPlaybackViewHeightConstraint?.constant {
self?.sharedUIPlaybackViewHeightConstraint?.constant = newHeight
}
}
).withAutoLayout().withAccessibilityIdentifier("test")
sharedUIPlaybackViewHeightConstraint = containerView.heightAnchor.constraint(equalToConstant: 0)
sharedUIPlaybackViewHeightConstraint?.isActive = true
I commented this math because is crashing the app and instead of giving a dynamical height I placed as a constant constraint as default height this is how I solved the problem of the UI, but I still need to update the view each time the user clicks and gets call by the method viewDidLayoutSubviewsCallback
what can I do?
I tried to add like a conditional on the method
if newHeight == 80 {
containerView.addConstraints([
swiftUIView.heightAnchor.constraint(equalToConstant: 80.0)
])
containerView.layoutIfNeeded()
}
else {
containerView.addConstraints([
swiftUIView.heightAnchor.constraint(equalToConstant: 206.33)
])
containerView.layoutIfNeeded()
}
like this but it didn't work
[this is how it looks with the constant value of 206.33]
[when it gets open looks good]
I have a UIKit app with a UIHostingController embedded as a child controller.
In this UIHostingController there's a SwiftUI view which expands and collapses with an animation to show/hide content within it.
The hosting controller uses .intrinsicContentSize sizing option.
This all works fine, and the animation of the expand/collapse looks good so far as the SwiftUI view, in a preview for example.
But running the app the hosting controller doesn't animate its view's size alongside the SwiftUI view animating its size.
Instead the hosting controller jumps from the correct start/end sizes without any animation.
So technically although it has the right size when the SwiftUI view is expanded/collapsed, this not a nice UX as the hosting controller jumps immediately from its small size to its larger one on expanding and vice versa for collapsing while the SwiftUI contents animates nicely.
I'm assuming there's somewhere I should be calling (in some form or another) a:
UIView.animate(withDuration: 0.4) {
hostingController.view.layoutIfNeeded()
}
alongside the SwiftUI animations - but I can't see any hook between my SwiftUI view .animation(value:) function and somewhere that hosting controller could jump in alongside this animation and animate its view's frame.

In order to setup a preview, I need to create a Book; to do that, I need to await a function – however, one cannot await inside a Preview:
import SwiftUI
struct BookView: View {
let book: Book
var body: some View {
VStack {
Image(book.thumbnail, scale: 1.0,
label: Text(book.title))
}
}
}
#Preview {
let url = URL(filePath: "/Users/dan/Documents/Curs confirmare RO.pdf")!
// 👇 here, `createBook` should be awaited; but how?
let book = createBook(for: url, of: CGSize(width: 254, height: 254), scale: 1.0)
BookView(book: book)
}
I recently updated my 16 pro to the latest software 18.4 developer beta. One issue i have encounter is that my always on display is not on or running in the background even tho the toggle option is ON. To fix this I have to go back to the setting and toggle the option back off and on.
I am using the standard SwiftUI component for subscription management, and on one device it is showing the user as unsubscribed when their sub is still in service.
The subscribe button is active but inert, doesn't do anything.
Ideas?
Hi. I thought the purpose of UndoManager.setActionIsDiscardable() was for this purpose - but the document still shows as edited.
These changes like changing the zoom/viewing area should not cause the document to be considered edited - but you'd still like to be able to undo them.
The documentation here https://developer.apple.com/documentation/foundation/undomanager/1415261-undoactionisdiscardable?changes=_6 even describes using it for just this purpose.
If this isn't the method, how can I do this? Thanks.

Hi,
I have few questions regarding the widgets.
I would like to know whether widget and app extensions are same ? This link(https://developer.apple.com/app-extensions/) says widget is type of app extension but I am not quite sure as few link in web says they are different. so need to confirm here :)
Can a widget share same bundle id as the main app ? so basically can we use the same provisioning profile as the main app?
If we use the same bundle id and provisioning profile, will there be any issue during the app store submission process.?
I am trying to discover how to display my application’s calculated Solar Information values in a chart.
My application identifies a selected location in MapKit.
The application identifies the location’s longitude, latitude, and current time of day.
The application calculates the selected location’s NOAA [SOLAR ELEVATION], and the [SOLAR AZIMUTH] for the time of day.
The application calculates the data, then stores the calculated values as a [Plist] file within my application’s Document Directory.
For the moment, complete with repeated scouring of the Internet, I am not sure how to properly convert, transfer, or create a Structure, required by the chart to display the calculated values. I would like to create the chart once the calculations are complete, but I introduced a Plist to store the calculations for future use, too.
The calculated values coincide with the NOAA Solar Calculations, complete to the displayed [h : m : s], whereas I also designed the application to create the [Array of Dictionary Objects] to store the calculated values for each subsequent six minute interval, until the end of the selected location’s day. The calculated values are properly appended to the [Array of Dictionary Objects] after each completed calculation, with data transfer constants. There are 240 calculations per day from [00:06:00 to 23:54:00], presented as a [STRING], complete with the [Elevation] presented as a [DOUBLE].
For example :: The application generates the following [Calculated Array of Dictionary Objects], then recreates, and appends a new Plist in the Document Directory.
mySolarElevationDataArrayOfDictionaries :: [(theRequiredTimeOfDay: "00:06:00", theCalculatedElevation: -62.60301082991259), (theRequiredTimeOfDay: "00:12:00", theCalculatedElevation: -62.94818095051292), (theRequiredTimeOfDay: "00:18:00", theCalculatedElevation: -63.245198186807215), (theRequiredTimeOfDay: "00:24:00", theCalculatedElevation: -63.49236786176319), (theRequiredTimeOfDay: "00:30:00", theCalculatedElevation: -63.688223890934175), (theRequiredTimeOfDay: "00:36:00", theCalculatedElevation: -63.831564163806945), (theRequiredTimeOfDay: "00:42:00", theCalculatedElevation: -63.921486675739004), (theRequiredTimeOfDay: "00:48:00", theCalculatedElevation: -63.95741610687708), to the end of the data :: ===> (theRequiredTimeOfDay: "23:54:00", theCalculatedElevation: -60.69355458181633)]
The application presents the initial data as follows ::
Then presents a compass view to illustrate the results ::
I modified the Chart’s [MOCK DATA] from the calculated values to test the Chart’s display in a [SwiftUI Hosting Controller].
For example :: The following Chart Mock Data in a [HourlySunElevation_MockChartData.swift] file is called by the application’s [Content View].
import Foundation
struct Value {
let theRequiredTimeOfDay: String
let theCalculatedElevation: Double
static func theSunElevationMockData() -> [Value] {
return [Value(theRequiredTimeOfDay: "00:06:00", theCalculatedElevation: -62.60301082991259), Value(theRequiredTimeOfDay: "00:12:00", theCalculatedElevation: -62.94818095051292), Value(theRequiredTimeOfDay: "00:18:00", theCalculatedElevation: -63.245198186807215), Value(theRequiredTimeOfDay: "00:24:00", theCalculatedElevation: -63.49236786176319), Value(theRequiredTimeOfDay: "00:30:00", theCalculatedElevation: -63.688223890934175), Value(theRequiredTimeOfDay: "00:36:00", theCalculatedElevation: -63.831564163806945), Value(theRequiredTimeOfDay: "00:42:00", theCalculatedElevation: -63.921486675739004), Value(theRequiredTimeOfDay: "00:48:00", theCalculatedElevation: -63.95741610687708), to the end of the data :: ===> Value(theRequiredTimeOfDay: "23:54:00", theCalculatedElevation: -60.69355458181633)]
The Chart illustrates the Mock Data as follows ::
I also created a Struct within the [MySunElevationChart_ViewController] to try to append the calculated data, using the same logic with the Plist data transfer constants, as employed by the [Array of Dictionary Objects] ::
struct ChartSolarElevationValues {
var theRequiredTimeOfDay: String
var theCalculatedElevation: Double
// Structs have an implicit [init]. This is here for reference.
init(theRequiredTimeOfDay: String, theCalculatedElevation: Double) {
self.theRequiredTimeOfDay = theRequiredTimeOfDay
self.theCalculatedElevation = theCalculatedElevation
//mySolarElevationChartData.append(self)
} // End of [init(theRequiredTimeOfDay: String, theCalculatedElevation: Double)]
} // End of [struct ChartSolarElevationValues]
Unfortunately, the result did not append each subsequent calculation, but continued to create the same calculation as a new distinct object ::
NOTE :: I only called three calculations with the Struct test.
// NOTE :: To prevent an [ERROR] at [var mySolarElevationChartData = [ChartSolarElevationValues]] since it has an init.
// Therefore you must add () at the end of [var mySolarElevationChartData = [ChartSolarElevationValues]]
let theData = [ChartSolarElevationValues]()
//print("theData :: \(theData)\n")
let someData = ChartSolarElevationValues(theRequiredTimeOfDay: TheTimeForDaySunElevation.theTheTimeForDaySunElevation, theCalculatedElevation:VerifyCityLocationSearchRequestCorrectedSolarElevation.theVerifyCityLocationSearchRequestCorrectedSolarElevation)
var theData_New = theData
theData_New.append(someData)
print("theData_New :: \(theData_New)\n")
// Prints :: theData_New :: [My_Map.ChartSolarElevationValues(theRequiredTimeOfDay: "00:06:00", theCalculatedElevation: -61.11000735370401)]]
// Prints :: [theData_New :: [My_Map.ChartSolarElevationValues(theRequiredTimeOfDay: "00:12:00", theCalculatedElevation: -61.315092082911875)]]
// Prints :: [theData_New :: [My_Map.ChartSolarElevationValues(theRequiredTimeOfDay: "00:18:00", theCalculatedElevation: -61.47403413313205)]]
So, I am misintepreting the required coding structure to properly append the Elevation Chart, and the Azimuth Chart with the calculated data.
I know something is amiss, but for the moment, I do not know how to address this issue.
Your suggestions would be welcome ... :]

TLDR: Applying a clipShape in a hoverEffect closure is preventing taps from getting through to buttons nested within an ornament.
I need to make a custom ornament menu, similar to the stock ornament available via TabView but with some visual tweaks. It displays icons, and then expands to display a label as the user hovers. Example:
I've put together a piece of sample code, following guidance from WWDC docs:
VStack {
}
.ornament(attachmentAnchor: .scene(.leading)) {
VStack {
ForEach(0...7, id:\.self) { index in
Button(action: {
print(index) // <---- This will not print
}) {
HStack {
Text("\(index)")
Text(" button")
}
}
}
}
.padding(12)
.glassBackgroundEffect()
.hoverEffect { effect, isActive, proxy in
effect
.clipShape(RoundedRectangle(cornerRadius: 36)
.size(width: isActive ? proxy.size.width : 72, height: proxy.size.height, anchor: .leading)
)
}
}
}
The buttons in this code cannot be interacted with, as the print statement never executes. What am I missing here? I've managed to get some weird behavior, sometimes a specific clipShape (like a circle) will allow a tap on a single button, but not others.
I am developing an app that's near release. I changed the minimum deployment from iOS 16.X to 17.0 in order to be able to use the TipKit Framework.
Making that change generated a ton of compiler warnings:
.onChange(of:perform:)' was deprecated in iOS 17.0: Use onChange with a two or zero parameter action closure instead.
After I fixed dozens of the warnings without issue, each subsequent attempt to fix a warning generated a compiler error:
The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions.
I decided to focus on just one file that had 13 different .onChange invocations. Nine were successfully converted to the new call, four were still deprecated. I tried to trace any possible source of type-check error for some of the simplest .onChange cases but nothing other than commenting out the .onChange in its entirety "fixed" the error.
I tried commenting out one of the fixed/converted .onChange calls first and then fixing one of the problematic ones and that worked, no type-check error. The bottom line seems to be that I can only have nine of the new .onChange calls in that file, the other four have to be in the deprecated format or commented out.
I tried upping the minimum deployment from 17.0 to 17.5 and that didn't work. I tried using a clean build folder and that also didn't work.
Right now, I'm running Xcode 15.4 on Sonoma 14.7.2. I'm trying to avoid updating to the latest Xcode to avoid adding confounding variables and/or other possible issues. I am aware that for submission and release I will have to do so, I want to do it "on my terms" when everything is working properly.
Any help would be appreciated.

In macOS 15.4 (24E5238a) and Xcode 16.2, the NSStatus images appear to be missing.
To reproduce, add an NSImageView to a Nib or StoryBoard and set the default image to any of the NSStatus images: NSStatusAvailable, NSStatusPartiallyAvailable, etc. Instead of the expected Green, Yellow dots, no image is displayed. The same occurs when setting images programatically.
Is the plan to remove these images, or is this just temporary?
I’m having a weird UIKit problem. I have a bunch of views in a UIScrollView and I add a UIContextMenuInteraction to all of them when the view is first loaded. Because they're in a scroll view, only some of the views are initially visible.
The interaction works great for any of the views that are initially on-screen, but if I scroll to reveal new subviews, the context menu interaction has no effect for those.
I used Xcode's View Debugger to confirm that my interaction is still saved in the view's interactions property, even for views that were initially off-screen and were then scrolled in.
What could be happening here?
To add a background to the tab content I implement the following background, nesting another modifier equal within this one.

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!
Hi, I'm working on visionOS and find I can't get onDisappear event just on the first window after app launch. It comes like that:
WindowGroup(id:"WindowA"){
MyView()
.onDisappear(){
print("WindowA disappear")
}
}
WindowGroup(id:"WindowB"){
MyView()
.onDisappear(){
print("WindowB disappear")
}
}
WindowGroup(id:"WindowC"){
MyView()
.onDisappear(){
print("WindowC disappear")
}
}
When the app first launch, it will open WindowA automatically
And then I open WindowB and WindowC programatically.
Then I tap the close button on window bar below window.
If I close WindowB/WindowC, I can receive onDisappear event
If I close WindowA, I can't receive onDisappear event
If I reopen WindowA after it is closed and then close it again by tap the close button below window, I can receive onDisappear event
Is there any logic difference for the first window on app launch? How can I get onDisappear Event for it.
I'm using Xcode 16 beta 2
