Given Apple's new .limited contact authorization introduced in ios18, I want to be able to present the ContactAccessPicker directly from my app, via ionic capacitor. I present the .contactAccessPicker view via a UIHostingController, and I manage the view controller's dismissal accordingly when the ContactAccessPicker completes and is no longer presented.
Bug: After a few searches or interactions with the Contact Access Picker (ex. searching, selecting contacts, clicking the "show selected" button), the contact access picker crashes and the overlay remains. Any interaction with my app is then blocked because I can't detect that the contact access picker has disappeared when it crashes so I can't dismiss the viewController.
Is there a way for me to prevent the contact access picker from crashing, and how can I detect if it does crash, so I can at least dismiss the view controller if that happens?
struct ContactAccessPickerView: View {
@Binding var isPresented: Bool
let completion: @MainActor ([String]) -> Void
var body: some View {
Group {
if #available(iOS 18.0, *) {
Color.clear
.contactAccessPicker(isPresented: $isPresented) { result in
Task { @MainActor in
completion(result)
}
}
} else {
}
}
}
}
@objc func selectMoreContacts(_ call: CAPPluginCall) {
guard isContactsPermissionGranted() else {
call.resolve(["success": false])
return
}
// Save the call to ensure it's available until we finish
self.bridge?.saveCall(call)
DispatchQueue.main.async { [weak self] in
guard let self = self else { return }
var isPresented = true
let picker = ContactAccessPickerView(isPresented: .init(get: { isPresented }, set: { isPresented = $0 })) { contacts in
call.resolve(["success": true])
self.dismissAndCleanup(call)
}
let hostingController = UIHostingController(rootView: picker)
hostingController.modalPresentationStyle = .overFullScreen
self.bridge?.viewController?.present(hostingController, animated: true)
}
}

I have an NSSplitViewController with three columns:
sidebar
full-height content view with NSScrollView/NSTableView
detail view.
There's no (visible) titlebar and no toolbar.
This layout has worked fine for years, but in Tahoe an unwanted overlay (~30-50px high) appears at the top of any column containing a scroll view with table content. Xcode suggests it's an NSScrollPocket.
My research suggests it...
Only affects columns with NSScrollView
Plain NSView columns are unaffected
Overlay height varies (~50px or ~30px depending on how I mess with title / toolbar settings)
Disabling titlebar/toolbar settings reduces but doesn't eliminate the overlay
The overlay obscures content and there doesn't appear to be any API
to control its visibility. Is this intended behavior, and if so, is
there a way to disable it for applications that don't need this UI
element?
If it helps visualise the desired result, the app is https://indigostack.app
Any guidance would be appreciated!

Help,I have encountered a thorny problem! In systems with iOS 16.5 and above, there is a probability that the keyboard will not disappear after it appears. And once it appears, unless the app is restarted, all places where the keyboard is used cannot be closed.
I have tried using the forced shutdown method [UIView endEditing:YES], but it didn't work. When this exception occurs, I notice that there will be two UITextEffectsWindow at the same time.
Does anyone know how to solve it?
I am encountering a critical issue where a custom background image on a UIToolbar fails to display when the app is built with Xcode 26 and run on iOS 26 beta. The exact same implementation works perfectly on iOS 18 and earlier versions.
We first attempted to use the legacy setBackgroundImage method, which fails to render the image on iOS 26:
// 1. Get Navigation Bar and set basic properties
UINavigationBar* navBar = self.navigationBar;
navBar.hidden = NO;
navBar.translucent = NO;
// 2. Setup the UIToolbar instance
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:navBar.bounds];
toolBar.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
// 3. Set the resizable image (This image does not appear on iOS 26)
UIImage* imagePortrait = [UIImage imageNamed:@"nav_bg"];
UIEdgeInsets insets = UIEdgeInsetsMake(0.f, 6.f, 0.f, 6.f);
[toolBar setBackgroundImage:[imagePortrait resizableImageWithCapInsets:insets]
forToolbarPosition:UIToolbarPositionAny
barMetrics:UIBarMetricsDefault];
We then migrated to the recommended modern UIToolbarAppearance to solve this, but the issue persists:
// 1. Prepare Image
UIImage* imagePortrait = [UIImage imageNamed:@"nav_bg"];
// Insets are applied via resizableImageWithCapInsets: (not shown in this snippet but implied)
// 2. Configure UIToolbarAppearance
UIToolbarAppearance *appearance = [[UIToolbarAppearance alloc] init];
appearance.backgroundImage = imagePortrait; // The image is correctly loaded (not nil)
// 3. Apply the Appearance
toolBar.standardAppearance = appearance;
// We also applied to scrollEdgeAppearance and compactAppearance.
Any information or recommended workarounds for displaying a custom background image on UIToolbar in the latest iOS 26 would be highly appreciated.
I have something that looks like:
NavigationStack {
List(self.items, id: \.self, selection: self.$selectedItems) { item in
NavigationLink {
ItemView(item: item)
.environment(\.managedObjectContext, self.viewContext)
} label: {
LabelWithMenuView(object: item) { ptr in
self.labelHandler(item: item, newName: ptr)
}
}
}
if self.editMode?.wrappedValue == .active {
editButtons
} else {
TextField("Add Item", text: self.$newItem)
.onSubmit {
self.addItem()
self.newItem = ""
}
.padding()
}
}
#if os(iOS)
.toolbar {
EditButton()
}
.onChange(of: self.editMode?.wrappedValue) { old, new in
print("editMode \(old) -> \(new)")
}
#endif
With that layout, the edit button doesn't show up at all; if I put it as part of the List, it does show up, but the first click doesn't do anything; after that, it works, but the onChange handler doesn't show it getting changed, and the editButtons don't go away.

I have find out that a UIViewRepresentable, even with a simples UIView, seems to never be dismantled when deleted from a ForEach and this can cause serious crashes.
In the following example you can observe this behavior by deleting a row from the list. The dismantleUIView function of SomeUIViewRepresentable or the deinit of SomeUIView are never called.
Has anyone faced this and found a solution for it?
I have also filled a Feedback: FB11979117
class SomeUIView: UIView {
deinit {
print(#function)
}
}
struct SomeUIViewRepresentable: UIViewRepresentable {
func makeUIView(context: Context) -> SomeUIView {
let uiView = SomeUIView()
uiView.backgroundColor = .systemBlue
return uiView
}
func updateUIView(_ uiView: SomeUIView, context: Context) { }
static func dismantleUIView(_ uiView: SomeUIView, coordinator: Coordinator) {

UITextView crash when setting attributed text that contains substring ffi and attributedText contains NSFontAttributeName, NSForegroundColorAttributeName
Reproducible case:
UITextView *textView = [[UITextView alloc] init];
textView.attributedText = [[NSAttributedString alloc] initWithString:@"ffi" attributes:@{
NSParagraphStyleAttributeName: [self createParagraphOfLineHeight:20],
NSFontAttributeName: [UIFont systemFontOfSize:fontSize weight:UIFontWeightRegular],
NSForegroundColorAttributeName: UIColor.black
}];
Hi community:
I noticed that each closure is counted as lines in code coverage (unit tests) (Xcode 14.1.0) in a swiftUI File. I mean, If you coded and VStack that involves another HStack, and HStack contains 4 lines, and the VStack contains 6 lines counting the HStack. The total executable lines should be 6 (6 lines in the file). But Xcode count 10, counting twice the HStack lines.
Is it a bug, or is it correct? You know, I don't know if Apple has another concept about executable lines.
Also, Is it possible to remove previews with any configuration from code coverage or constant files?
Thanks for all.
It seems like it is no longer possible to open the main window of an app after the app has been launched by the system if the "Auto Start" functionality has been enabled.
I am using SMAppService.mainApp to enable to auto start of my app. It is shown in the macOS system settings and the app is automatically started - but the main window is not visible.
How can I change this behaviour so the main window of the app is always visible when started automatically?
I have not noticed this behaviour before the release of macOS Sequoia. My app is using Swift 6 and the latest version of macOS and Xcode.
Regards

When I add a TextField with @FocusState to a toolbar, I noticed that setting focus = false doesn't cause the form to lose focus
If I move the TextField out of the toolbar setting focus = false works fine. How can I unfocus the text field when the cancel button is tapped?
Minimal example tested on Xcode Version 26.0 beta 6 (17A5305f):
import SwiftUI
struct ContentView: View {
@State private var text: String = ""
@FocusState private var focus: Bool
var body: some View {
NavigationStack {
List {
Text("Test List")
}
.toolbar {
ToolbarItem(placement: .bottomBar) {
TextField("Test", text: $text)
.padding(.horizontal)
.focused($focus)
}
ToolbarItem(placement: .bottomBar) {
Button(role: .cancel) {
focus = false // THIS DOESN'T WORK!
}
}
}
}
}
}
#Preview {
ContentView()
}```
Hi everyone,
I have the following issue that I have tried to tweak every possible modifier of ScrollView and still got the same result in iOS 26.
Description:
Create a SwiftUI ScrollView with scrollTargetBehavior of paging, also create a bottom UI view below the ScrollView.
If the starting index is not 0, the position of current page will be off with part of previous page shown above it.
It only happens on iOS 26, not on iOS 18.
Also if bottom UI view (text view in this case) is removed, it also works fine.
I want to see if there is a solution for it or it's an iOS 26 bug. Thanks!

Is there a way to access an Icon Composer .icon file in Swift or Objective-C? Any way to get this in an NSImage object that I can display in an image view? Thanks.
Given a sheet with [.medium] detents, that contains a native ColorPicker in SwiftUI:
struct SheetView: View {
@State var color: Color = .white
var body: some View {
ColorPicker(
"Color",
selection: $color,
supportsOpacity: false
)
.padding()
}
}
struct ContentView: View {
@State var isSheetOpen = false
var body: some View {
Button("Open Sheet") {
isSheetOpen = true
}
.sheet(isPresented: $isSheetOpen) {
SheetView()
.presentationDetents([.medium])
}
}
}
When I tap the ColorPicker's color indicator button, it presents the color picker sheet with a layout glitch.
During the color picker presentation animation, the original sheet (SheetView) is rapidly pushed up and back down.
It is a wild guess but I think it has to do something with keyboard avoidance.
Unfortunately, this makes it impossible to use the picker in my app....
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 trying to understand a design pattern for accessing the isolated state held in an actor type from within a SwiftUI view.
Take this naive code:
actor Model: ObservableObject {
@Published var num: Int = 0
func updateNumber(_ newNum: Int) {
self.num = newNum
}
}
struct ContentView: View {
@StateObject var model = Model()
var body: some View {
Text("\(model.num)") // <-- Compiler error: Actor-isolated property 'num' can not be referenced from the main actor
Button("Update number") {
Task.detached() {
await model.updateNumber(1)
}
}
}
}
Understandably I get the compiler error Actor-isolated property 'num' can not be referenced from the main actor when I try and access the isolated value. Yet I can't understand how to display this data in a view. I wonder if I need a ViewModel that observes the actor, and updates itself on the main thread, but get compile time error Actor-isolated property '$num' can not be referenced from a non-isolated context.
class ViewModel: ObservableObject {
let model: Model
@Published var num: Int
let cancellable: AnyCancellable
init() {
let model = Model()
self.model = model
self.num = 0
self.cancellable = model.$num // <-- compile time error `Actor-isolated property '$num' can not be referenced from a non-isolated context`
.receive(on: DispatchQueue.main)
.sink { self.num = $0 }
}
}
Secondly, imagine if this code did compile, then I would get another error when clicking the button that the interface is not being updated on the main thread...again I'm not sure how to effect this from within the actor?
Hello,
I have been receiving crash reports on iOS 26 related to a view containing a UITextField. Although I have not been able to reproduce the issue locally and the exact reproduction steps are unknown, the call stack suggests the crash may be related to language or input method changes.
If anyone has encountered a similar crash on iOS 26 or has any insights regarding language/input-related issues impacting UITextField behavior, your help would be greatly appreciated. The call stack from the reports is attached below.

I'm trying to create a List that allows multiple selection. Each row can be edited but the issue is that since there's a tap gesture on the Text element, the list is unable to select the item.
Here's some code:
import SwiftUI
struct Person: Identifiable {
let id: UUID
let name: String
init(_ name: String) {
self.id = UUID()
self.name = name
}
}
struct ContentView: View {
@State private var persons = [Person("Peter"), Person("Jack"), Person("Sophia"), Person("Helen")]
@State private var selectedPersons = Set<Person.ID>()
var body: some View {
VStack {
List(selection: $selectedPersons) {
ForEach(persons) { person in
PersonView(person: person, selection: $selectedPersons) { newValue in
// ...
}
}
}
}
.padding()
}
}
struct PersonView: View {
var person: Person
@Binding var selection: Set<Person.ID>
var onCommit: (String) -> Void = { newValue in }
@State private var isEditing = false
@State private var newValue = ""
@FocusState private var isInputActive: Bool
var body: some View {
if isEditing {
TextField("", text: $newValue, onCommit: {
onCommit(newValue)
isEditing = false
})
.focused($isInputActive)
.labelsHidden()
}
else {
Text(person.name)
.onTapGesture {
if selection.contains(person.id), selection.count == 1 {
newValue = person.name
isEditing = true
isInputActive = true
}
}
}
}
}
Right now, you need to tap on the row anywhere but on the text to select it. Then, if you tap on the text it'll go in edit mode.
Is there a way to let the list do its selection? I tried wrapping the tap gesture in simultaneousGesture but that didn't work.
Thanks!
In a TabView with the .sidebarAdaptable style, including TabSection elements prevents the default back swipe on the remote from revealing the sidebar. Removing all TabSection elements and using only Tab elements makes it work as expected:
import SwiftUI
struct ContentView: View {
var body: some View {
TabView {
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
TabSection("Section") {
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
Tab("Tab", systemImage: "square.fill") { Button(action: {}) { Text("Button") } }
}
}.tabViewStyle(.sidebarAdaptable)
}
}
Am I using it wrong, or is this a bug?
It appears that hidesBottomBarWhenPushed no longer works in iOS 26 Beta 1.
Is it supposed to work, is it going away or is there a alternate behavior we should be using?
