SWIFTU UI - Graph package similar to Neo4J GUI
Is there a good library / opensource package for Graph library similar to Neo4J GUI (pl.see attached) I tried few of the below, looking for something better https://medium.com/better-programming/building-a-graph-with-swiftui-b16dc48f7fe6 https://github.com/palle-k/Graphite

.contentMargins(.top, 0, for: .scrollContent) has no effect on .plain List with section headers (iOS 17 & 18)
I'm trying to remove the extra top padding from the first section of a SwiftUI List using .plain style. I applied: .contentMargins(.top, 0, for: .scrollContent) But it seems to have no effect on iOS 17 and iOS 18.5 when section headers are present. However, it does work correctly on iOS 26 (tested with the latest Xcode beta). Has anyone else run into this? Is this a known issue or regression in iOS 17/18? Is there any reliable workaround to remove or reduce the top padding in .plain list style when using section headers? I have screenshots comparing iOS 18.5 and iOS 26 if needed. Thanks in advance!

NavigationSplitView content column renders list in plain style – even on iPhone
Hi everyone, I’m building an iOS app that originally targeted iPhone using NavigationStack. Now I’m adapting it for iPad and switched to using NavigationSplitView to support a three-column layout. The structure looks like this: NavigationSplitView { A // Sidebar } content: { B // Middle column – this shows a list } detail: { C // Detail view } The issue is with the list shown in view B (the content column). It appears completely unstyled, as if it’s using .listStyle(.plain) — with no background material, and a very flat look. I can understand that this might be intentional on iPad to visually distinguish the three columns. However, the problem is that this same unstyled list also appears on iPhone, even though iPhone only shows a single column view at a time! I tried explicitly setting .listStyle(.insetGrouped) or .listStyle(.grouped) on the list in view B, but it makes no difference. When I go back to NavigationStack, the list in B is styled properly, just as expected — but then I lose the enhanced iPad layout. What I’m looking for: I’d like to keep using NavigationSplitView, but I want the list in the content column (view B) to use the default iOS list styling, at least on iPhone. Is there any way to achieve this? Thanks!

How is the transition effect in Apple’s Calendar app built (month → day view)?
Hi everyone, I’m trying to recreate the beautiful transition effect used in Apple’s built-in Calendar app — specifically the one where, when you tap on a month, you’re “pulled into” the next view, and when going from month to day, the views seem to slide vertically, almost as if one is pushing the other off-screen. It’s not the standard right-to-left slide you get with NavigationStack or NavigationLink, and it feels much more immersive and dynamic. I’ve been experimenting with .matchedGeometryEffect and .transition(.move(...)) in a ZStack, and while I can replicate some aspects, I’m still missing that fluid, directional pull that makes it feel like you’re diving deeper into the calendar. I’m also unsure how much the view structure between the source and destination needs to match for the matchedGeometryEffect to really shine. Does anyone know what APIs or techniques Apple might be using internally to build that kind of animation? Is there a clean way to achieve something similar using SwiftUI as of iOS 17 or 18? Would love to hear if someone here has successfully replicated this or has tips on best practices. Thanks in advance!

On macOS, how do you place a toolbar item on the trailing edge of the window's toolbar when an Inspector view is open?
Using SwiftUI on macOS, how can I add a toolbar item on the right-most (trailing) edge of the window's toolbar when an Inspector is used? At the moment, the toolbar items are all left-of (leading) the split view tracking separator. I want the inspector toolbar item to be placed similar to where Xcode's Inspector toolbar item is placed: always as far right (trailing) as possible. NavigationSplitView { // ... snip } detail: { // ... snip } .inspector(isPresented: $isInspectorPresented) { InspectorContentView() } .toolbar { // What is the correct placement value here? ToolbarItem(placement: .primaryAction) { Button { isInspectorPresented.toggle() } label: { Label("Toggle Inspector", systemImage: "sidebar.trailing") } } } See the attached screenshot. When the InspectorView is toggled open, the toolbar item tracks leading the split view tracking separator, which is not consistent with how Xcode works.

PresentationDetent to auto-size sheet to the height of the contained Views
(Also submitted as FB19359821) I suggest a PresentationDetent.sizeToFit or PresentationDetent.contentSize that automatically sizes the sheet to the height of the contained Views. This seems to be a common requirement for many app developers and it would be nice if this would be supported out of the box without fiddling around with the usual GeometryReader in background -> make available the height with a preference key -> .presentationDetents([.height(…)]) workarounds.

Scroll to Top gesture breaks when setting List or ScrollView background
When a ScrollView or List is nested in a TabView, you can press on the tab button and the scroll view will scroll to top. import SwiftUI struct SwiftUIView: View { let items = (1...100).map { "Item \($0)" } var body: some View { TabView { Tab("home", systemImage: "house") { ScrollView { ForEach(items, id: \.self) { item in Text(item) .frame(maxWidth: .infinity, alignment: .center) } } } } } } #Preview { SwiftUIView() } But if we add a background to the ScrollView, the scroll to top gesture breaks. import SwiftUI struct SwiftUIView: View { let items = (1...100).map { "Item \($0)" } var body: some View { TabView { Tab("home", systemImage: "house") { ScrollView { ForEach(items, id: \.self) { item in Text(item) .frame(maxWidth: .infinity, alignment: .center) } } // Set background on ScrollView. .background(Color.red) } } } } #Preview { SwiftUIView() } I made a similar post on StackOverflow, but haven't been able to find a proper solution. This feels like a bug of some sort in SwiftUI.

Change iOS Keyboard Language without adding to Settings > Keyboards
The first-party Apple Translate app will switch the on-screen keyboard to the selected language, even when the keyboard for that language is NOT added in Settings > General > Keyboards. We'd like to mirror this behavior and switch the keyboard for input based on a user-selected language from a drop-down without the user needing to add that language to Keyboards I'm struggling to find if this behavior is achieved via a public API. Any insights here?

iOS 26 AttributedString TextEditor bold and italic
Is there a way to constrain the AttributedTextFormattingDefinition of a TextEditor to only bold/italic/underline/strikethrough, without showing the full Font UI? struct CustomFormattingDefinition: AttributedTextFormattingDefinition { struct Scope: AttributeScope { let font: AttributeScopes.SwiftUIAttributes.FontAttribute let underlineStyle: AttributeScopes.SwiftUIAttributes.UnderlineStyleAttribute let strikethroughStyle: AttributeScopes.SwiftUIAttributes.StrikethroughStyleAttribute } var body: some AttributedTextFormattingDefinition<Scope> { ValueConstraint(for: \.font, values: [MyStyle.defaultFont, MyStyle.boldFont, MyStyle.italicFont, MyStyle.boldItalicFont], default: MyStyle.defaultFont) ValueConstraint(for: \.underlineStyle, values: [nil, .single], default: .single) ValueConstraint(for: \.strikethroughStyle, values: [nil, .single], default: .single) } } If I remove the Font attribute from the scope, the Bold and Italic buttons disappear. And if the Font attribute is defined, even if it's restricted to one typeface in 4 different styles, the full typography UI is displayed.

Animate colours in a SwiftUI Canvas
Pseudo-code: PhaseAnimator([false,true], trigger: foo) { flash in ZStack { Capsule() .foregroundStyle(flash ? .red : .green) Canvas { context, size in context.draw(image: Image(name: "foo"), toFitRect: some_rectangle); context.draw(text: Text("foo"), toFitRect: another_rectangle); } .foregroundStyle(flash ? .black : .white) } } animation: { flash in return .linear(duration: 0.5); } The Capsule's colour animates, but the Canvas's doesn't. The Canvas drawing code is only ever called with flash==false. What do I have to do to the Canvas so that it redraws with the intermediate colours during the animation?

When removing a ToolbarItem from the navigation bar, how do I make the remaining ToolbarItems resize correctly?
Because .searchable does not allow for customizing buttons in the search bar, I've manually had to recreate the search bar as shown below. However, when removing one of the items in the search bar, the TextField does not resize correctly and effectively inserts padding on the leading edge. When the TextField is focused, it resizes and fills the entire space. If the "Compose" button was already hidden when the search bar is presented, it lays out correctly. How do I resize the TextField after removing the "Compose" button automatically? Thanks, jjp struct ContentView: View { @State var isSearchBarVisible = false @State var isComposingMessage = false @State var searchText = "" let items: [String] = ["hey", "there", "how", "are", "you"] var searchItems: [String] { items.filter { item in item.lowercased().contains(searchText.lowercased()) } } var body: some View { NavigationStack { VStack { List { if !searchText.isEmpty { ForEach(searchItems, id: \.self) { item in Text(item) } } else { ForEach(items, id: \.self) { item in Text(item) } } } } .toolbar { if isSearchBarVisible { ToolbarItem(placement: .principal) { TextField("Search", text: $searchText) .padding(8) .background(Color.gray.opacity(0.2)) } ToolbarItem(placement: .topBarTrailing) { Button(action: { isSearchBarVisible = false },[![enter image description here][1]][1] label: { Text("Cancel") }) } if !isComposingMessage { ToolbarItem(placement: .topBarTrailing) { Button(action: { isComposingMessage.toggle() }, label: { Text("Compose") }) } } } else { ToolbarItem(placement: .topBarLeading) { Button(action: { isSearchBarVisible = true }, label: { Text("Search") }) } ToolbarItem(placement: .principal) { Text("Title") } ToolbarItem(placement: .topBarTrailing) { Button(action: { isComposingMessage.toggle() }, label: { Text("Compose") }) } } } } } }

[iOS 26] iOS App Does Not Receive Deep Link from Widget When Using widgetAccentedRenderingMode on Image
Summary When a SwiftUI widget uses a Link containing an Image modified with .widgetAccentedRenderingMode (using any mode except .fullColor), tapping the image on the widget launches the app but does not pass the expected deep link URL to the SceneDelegate. Steps to Reproduce Create a SwiftUI Widget View with a Link: struct ImageView: View { var image: UIImage var body: some View { Link(URL(string: "myapp://image")!) { Image(uiImage: image) .resizable() .widgetAccentedRenderingMode(.accentedDesaturated) // or any mode other than .fullColor .scaledToFill() .clipped() } } } Add Custom URL Scheme in Info.plist: <dict> <key>CFBundleURLName</key> <string>com.company.myapp</string> <key>CFBundleURLSchemes</key> <array> <string>myapp</string> </array> </dict> Implement Deep Link Handling in SceneDelegate: func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) { if let url = connectionOptions.urlContexts.first?.url { handle(url) } } func scene(_ scene: UIScene, openURLContexts urlContexts: Set<UIOpenURLContext>) { if let url = urlContexts.first?.url { handle(url) } } private func handle(_ url: URL) { // Process URL here } Run the application on a device or simulator. Add the widget to the Home Screen. Tap the image inside the widget. Expected Result The application launches and receives the URL in SceneDelegate, as expected. Actual Result The application launches, but the URL is not passed to SceneDelegate. Both connectionOptions.urlContexts and openURLContexts are empty.

SwiftUI Navigation - Top toolbar breaks and app is unusable
We've been trying to track down a non-reproducible issue for the past few months, and I'm wondering if anybody has encountered the same one. Screenshots of the issue attached here. As you can see, the toolbar isn't respecting the safe area; there are many more issues that occur when this bug happens as well, such as the app being extremely laggy and sheets not opening. Anecdotally, this seems to happen if the app is opened after not having been opened in a while (say, a day or so). It tends to happen first thing in the morning when I open the app, but as I mentioned, it's been very hard to reproduce. I'm also wondering if it's a known SwiftUI navigation issue or if anyone has encountered this.

Tinting/Coloring tabs when using SidebarAdaptableTabViewStyle like List
SwiftUI.List allows for customization using .listItemTint, .tint, or .foregroundStyle. This can be used to color individual items in the list, other than the app's specified accent color. Is there an equivalent feature to customize individual Tab's icon or label, when using TabView's SidebarAdaptableTabViewStyle, and its in the sidebar style. From what I understand, there needs to be a modifier applied directly to Tab unlike List, and not just the label. Since there isn't any color/tint modifiers, is it not possible?

NavigationSplitView not fully supported on smaller (SE) iPhones
My SwiftUI code runs fine on macOS, iOS(iPad) and larger iPhones, but will not display the detail view on smaller iPhones. Is there a way to force the smaller iPhones to display the detail view? And if not, When I put the App on the Apple store, for sale, will the Apple store be smart enough to flag the App as not appropriate for smaller iPhones, such as the SE (2nd and 3rd gen.) and prevent downloads? Thanks in advance for any guidance.

ProductView failed to trigger purcahse flow.
Hi, My app has an IAP and the view that let user to purchase is simply a ProductView. The purchase flow should be handled by the ProductView itself. I have tested the app with xcode storekit configuration, xcode run with sandbox account and also TestFlight environment as well. The purchase is triggered and the app feature is unlocked after purchase. However, I keep getting app review team feedback with the following problem: Bug description: the purchase button is greyed out after we tapped on it, however, there's no purchase flow popped up I have tried multiple things. Building with xcode cloud, removing the storekit configuration from the build scheme. But none can get the app review team to get through the problem. The IAP is not available in certain region. In that case, the app will show a message. However, the app review attached an screenshot which shows the product view. The view that allow users to purchase if let product = store.products.first(where: { $0.id == "com.xxx.xxxxxxx" }) { // If the product is available, show the ProductView ProductView(id: product.id) .productViewStyle(.compact) } else { // If the product is not available, show a message Text("In-app purchase is not available in your region.") } The store class @Published private(set) var products: [Product] = [] ... init() { //To handle the parental approval flow getUpdateTransaction() } func getUpdateTransaction() { updates = Task { for await update in StoreKit.Transaction.updates { if let transaction = try? update.payloadValue { await fetchActiveTransactions() await transaction.finish() } } } } Does anyone what can go wrong with ProductView? As this is part of the StoreKit API, I don't know what can go wrong. At least the purchase flow should be covered by it. Also, is sandbox and TestFlight a good way to test IAP? Thanks!
