.onAppear and .task code not running
Hi, I have the following code, which for some reason is not working as expected. I have an .onAppear and a .task function that isn't running, which I can see isn't running because nothing is printing. Any guidance would be greatly appreciated. Thank you. struct ContentView: View { var body: some View { ZStack { switch view { case .view1: View1() case .view2: View2() case .view3: View3() case .view4: View4() case .view5: View5() default: SubscriptionStoreView(groupID: "") } } .onAppear() { view = .view6 print("test 1") } .task { print("test") await refreshPurchasedProducts() } } func refreshPurchasedProducts() async { // Iterate through the user's purchased products. for await verificationResult in Transaction.currentEntitlements { switch verificationResult { case .verified(let transaction): print("verified") case .unverified(let unverifiedTransaction, let verificationError): print("unverified") default: print("default") } } } }

Rendering Multi-Page PDF with SwiftUI View
I have the following code that renders a one-page PDF: func render() -> URL { let renderer = ImageRenderer(content: pdfView()) let url = URL.documentsDirectory.appending(path: "filename.pdf") renderer.render { size, context in var document = CGRect(x: 0, y: 0, width: 2550, height: 3300) guard let pdf = CGContext(url as CFURL, mediaBox: &document, nil) else { return } pdf.beginPDFPage(nil) context(pdf) pdf.endPDFPage() pdf.closePDF() } return url } func pdfView() -> some View { Text("View") } How can this be modified so that it renders a PDF with more than one page?

IS THE SWiPE LEFT CAMERA MODE REALLY IMPORTANT?
I have really examined the swipe left Camera function mode and sincerely believe it is no more important especially when there no option in the settings to turn it on or off. I will highly recommend a total scrap in the iOS 26 or if possible a function to activate and deactivate it.

New to macOS Development. How Do I Build a Timeline Editor UI Like Logic Pro?
Hi everyone, I’m new to macOS development and working on an app idea that needs a timeline-based editor interface, similar to what you see in Logic Pro or Final Cut. The UI I want to build would have: A horizontal beat ruler that follows BPM and shows beat positions Several vertical tracks stacked below it (for things like events or markers) Horizontal zooming and scrolling A preview panel on the right side that stays in sync with the timeline I’m currently trying this in SwiftUI, but I’m running into some limitations and wondering if AppKit would be a better fit, or maybe a hybrid of the two. My questions: Where should I start when building something like this? What’s the best way to make the beat ruler and all track layers scroll together? How should I handle zooming in/out and syncing the display to a BPM timeline? Is there a clean way to integrate AppKit for the timeline view while keeping SwiftUI elsewhere?

Modal Shadows - In App Purchases (macOS)
Hey, everyone. I'm having an issue with my modal shadows when building for macOS. I've attached an image to show you what's going on. I have a rounded corner window, and when the In-App Purchase overlay opens, the modal shadow of that rounded window is square (which doesn't make sense, and looks bad). Can somebody please help me address this? I've tried searching high and low for a solution but I can't find anything :-( I really appreciate you taking a look! -Logan

New IOS APP Help
Hello, I am looking to develop a relationship with a developer that has experience running through the IOS build approval process. To elaborate, my team and I have designed and built a software application which is working through the Apple Developer review process to have the app approved and released to the App Store. Unfortunately, there has been some challenges, simple challenges in my eyes with our interface preventing Apple from approving our application. Happy to elaborate further. A primary problem and solution I have seen is the software build was testing solely on the iPhone but as recently directed it seem the application must be accessible on iPad as well. With this the case, I have experience some software platforms where on the ipad the interface is not displayed on the whole screen. I am looking for direction on how to implement this setup for the 1st IOS build. Another concern from Apples Developer Review team is the App Tracking Transparency kit may need to be implemented.

How to highlight the specific POI in the map on scroll
Hello, I have used CPPointOfInterestTemplate for displaying data and as user scrolls using the up/down arrow, I do not see any change in the map. Is there a way to highlight the POIs as the user scrolls through the list? I need to use the map controls and zoom to check the markers on the map. Is it possible to set the zoom level of the map in CarPlay? Pls suggest on the above queries

Avoid using a segmented control in a toolbar
Hi, in the Human Interface Guidelines, Apple writes: Avoid using a segmented control in a toolbar. Toolbar items act on the current screen — they don’t let people switch contexts like segmented controls do. Along with this image: Source I'm confused by this example. The screenshot seems to be showing a segmented control in a toolbar. Is this saying that the Phone app's All/Missed toggle is different from a segmented control? Under iOS 26 it seems to take a different style compared to a regular segmented control. If so, which component is used to create this filter? Could you please clarify the guidelines? Thank you.

Questions about the Swift Student Challenge
Hello! I've been wondering about how strict the rules are for multilingual content in submissions, and also what I can use as screenshots. There are screens in my app, explained and accompanied by English, that have Chinese text/audio on them. Is this appropriate? Reading the Terms & Conditions says that "All content must be in English", but because multicultural themes are a main point of my app, it seems unavoidable to use other languages. I've attached images that show what I'm talking about: About the screenshots in my submission, am I allowed to show two screenshots side-by-side of a before & after of what an interaction does in one image? It'd look like two phone screenshots right next to each other.

Any chance of still joining the UX Writing Lab?
I have accidentally missed the sign up window for the UX Writing lab by 1 hour, but I'd still love to join it if at all possible. I have had this lab several times in the past and it was always very informative. I have a time tracking app that helps people make the most of their time. https://apps.apple.com/us/app/timelines-time-tracking/id1112433234 I'm looking for guidance on how to improve copywriting in my onboarding sequence, on my paywall, and overall throughout the app. Thank you for considering. My Apple ID is lukas[at]glimsoft.com.

HotKey support for sandboxed apps
App design: macos, Xcode 16.4, Sequioa 15.5, it is sandboxed Uses: Pods->HotKey for a global hotkey which xcode says "binary compatibility can't be guaranteed" This app is on the Apple Store and supposedly apps on the Apple Store can't use global hotkeys. Someone internally, installed it from the store and the global hotkey works just fine. I'm concerned for two potential problems; I need to find a hotkey library or code that is known to work with a sandbox'd Apple Store app. Why is it working now when everything I have read says it shouldn't.

Poor Rendering of Liquid Glass Icon on Device
Hey there, I redesigned my apps icons for Liquid Glass in the icon composer app. I have to say it's been a pleasure to use and my icons look stunning when rendered in the icon composer app, whatever rendering mode and context I've been testing. But once in a developer release on my device (iOS 26 beta 3), the rendering is very disappointing. They look blurry, very far from what icon composer is showing. I would like to know whether I have a design issue, or if the current state of the beta release is known to not render icon properly. I'm kind of panicking :)

NFC Bottomsheet customization
Hi all, I wanted to check whether the NFC bottom-sheet UI shown by iOS during an NFC reading session can be customized. We have a Figma design (attached) for how the sheet should look, but we are not sure whether iOS allows modifying the default NFC UI. Is UI customization supported, or is the bottom sheet fully controlled by the system? Thanks in advance.
