Error creating the CFMessagePort needed to communicate with PPT. Type: Error | Timestamp: 2025-02-10 13:43:41.450089-06:00 | Process: junk removal app | Library: UIKitCore | Subsystem: com.apple.UIKit | Category: PPT | TID: 0xf185c
I have completed a code with chatgpt and I am unising the latest version of code. i am also using an m1 MacBook air (2020). would love to know if anyone have resolved this issue. by using the ai to correct the code it disrupts it with something. an incorrect imoout line,but after multiple attempts ai get it right. I have notice that the code shows up on the start meaning run, take some time to load the intro page.

About tvOS Material (design resource)
I noticed a discrepancy between the Material specifications for tvOS on the Developer page and the naming in the Design Resources (Sketch files). Which one should we consider authoritative? https://developer.apple.com/design/human-interface-guidelines/materials

Keyboard dismissed when switching apps
Scenario is when keyboard is opened within the app being developed then switch to other app, for instance, Notes app and create a note to enable keyboard from there. While the Notes app keyboard is active switch back to the developed app the keyboard in it is dismissed. Any thoughts?Thanks

A Summary of the WWDC25 Group Lab - Design
At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for Design. Can you expand on how Liquid Glass helps with navigation and focus in the UI? Liquid Glass clarifies the navigation layer by introducing a single, floating pane that acts as the primary navigation area. Buttons within this pane seamlessly morph as you move between sections, and controls can temporarily lift into the glass surface. While avoiding excessive use of glass (like layering glass on glass), this approach simplifies navigation and strengthens the connection between menus, alerts, and the elements that trigger them. What should I do with customized bars that I might have in my app? Reconsider the content and behavior of customized bars. Evaluate whether you need all the buttons and whether a menu might be a better solution. Instead of relying on background colors or styling, express hierarchy through layout and grouping. This is a good opportunity to adopt the new design language and simplify your interface. What are scroll edge effects, and what options do we have for them? Scroll edge effects enhance legibility in controls by lifting interactive elements and separating them from the background. There are two types: a soft edge effect (a subtle blur) and a hard edge effect (a more defined boundary for high-legibility areas like column sorting). Scroll edge effects are designed to work seamlessly with Liquid Glass, allowing content to feel expansive while ensuring controls and titles remain legible. How can we ensure or improve accessibility using Liquid Glass? Legibility is a priority, and refinements are ongoing throughout the betas. Liquid Glass adapts well to accessibility settings like Reduce Transparency, Increase Contrast, and Reduce Motion. There are two variants of glass: regular glass, designed to be legible by default, and clear glass, used in places like AVKit, which requires more care to ensure legibility. Use color contrast tools to ensure contrast ratios are met. The Human Interface Guidelines (HIG) are a living document offering best practices. The colors and materials pages are key resources. Do you have any recommendations for convincing designers concerned with consistency across Android and Web to use Liquid Glass? Start small and focus on high-utility controls that don't significantly impact brand experience. Native controls offer familiarity and predictability to users. Using the native controls makes sure your app feels at home on the device. Using native frameworks provides built-in accessibility support (dynamic type, reduce transparency, increase contrast). Native controls come with built-in behaviors and interactions. Can ScrollViews include Liquid Glass within them? You can technically put a glass layer inside a scroll view, but it can feel heavy and doesn't align with the system's intention for Liquid Glass to serve as a fixed layer. Think of the content layer as the scrolling layer, and the navigational layer as the one using Liquid Glass. If there is glass on the content layer it will collide into the navigational layer. What core design philosophy guided the direction of iOS 26, beyond the goal of unification? The core design philosophy involved blurring the line between hardware and software, separating UI and navigation elements from content, making apps adaptable across window sizes, and combining playfulness with sophistication. It was about making the UI feel at home on rounded screens. Can we layer Liquid Glass elements on top of each other? Avoid layering Liquid Glass elements directly on top of each other, as it creates unnecessary visual complexity. The system will automatically convert nested glass elements to a vibrant fill style. Use vibrant fills and labels to show control shapes and ensure legibility. Opaque grays should be avoided in favor of vibrant colors, which will multiply with the backgrounds correctly. What will happen to apps that use custom components? Should they be adapted to the new design within the next year? The more native components you use, the more things happen for free. Standard components will be upgraded automatically. Look out for any customizations that might clash. Think about what is the minimum viable change, where your app still feels and looks very similar to what it did. Prioritize changes in core workflows and navigational areas. There are a number of benefits to using native components including user familiarity, built-in accessibility support, and built-in behaviors and interactions. Will Apple be releasing Figma design templates? Sketch kits were published on Monday and can be referenced. The goal is to ensure the resources are well-organized, well-named, and easy to use. It's a high priority.

Guideline 4.3(a) - Design - Spam
Hello, I recently submitted my app to the Apple Store and received a rejection under Guideline 4.3(a) - Design - Spam, stating that my app is similar to others on the store. However, my app has a unique feature set, offers more functionality and content than competitors, and is completely free with ad monetization, unlike most similar apps that require subscriptions. I have spent five months developing this app from scratch, ensuring it provides an original and valuable experience for users. I did not use an app template or repackaged code, and my app is not a reskinned version of any existing app. I genuinely believe it brings meaningful differentiation to the market. I would appreciate any guidance on how I can better communicate my app’s uniqueness to the review team or what specific aspects I should adjust to comply with Apple's guidelines. Thank you for your time and support.

How can this be resolved - load_eligibility_plist: Failed to open //private/var/db/os_eligibility/eligibility.plist: Operation not permitted(1)
I'm programming my constraints in my video game, which is working good so far until I ran into my most important interactive storyboard. I have three buttons that move back and forth on the Y position each time they are hit. The buttons Y positions only change to view.safeAreaLayoutGuide.centerYAnchor, constant: 100 or view.safeAreaLayoutGuide.centerYAnchor, constant: 200 or view.safeAreaLayoutGuide.centerYAnchor, constant: 300 The strange part is the button that is in the Y 100 stays visible and I can hit the button that is in the Y 100. The buttons in the Y 200 and Y 300 positions are visible until after one or two hits, then the button that is in Y 300 position disappears, then after another hit or two the button that is in the Y 200 position disappears but the button that is in the Y 100 is still visible. I cleared all my constraints to narrow it down to clear view of the constraints that is causing the problem. I do not think this Log Noise. Below is the error log: load_eligibility_plist: Failed to open //private/var/db/os_eligibility/eligibility.plist: Operation not permitted(1) 1 Unable to simultaneously satisfy constraints.

Progress Ring Artifact
I'm working to emulate the Activity Rings featured in Apple's Fitness app. Here's a copy of what's in the swift file so far. // // ProgressRingPrototype.swift // Nutrition // // Created by Derek Chestnut on 1/13/25. // import SwiftUI struct ProgressRingPrototype: View { @State var progress = 0.00 let size: CGSize let thickness: CGFloat var color: Color? var gradientColors: [Color]? var body: some View { let color = color ?? .primary ZStack { RingPrototype( size: self.size, thickness: self.thickness, color: color.opacity(0.2) ) let gradient = AngularGradient( colors: gradientColors ?? [.primary, .secondary], center: .center ) let style = StrokeStyle( lineWidth: 32, lineCap: .round ) Circle() .trim(from: 0, to: progress) .stroke(gradient, style: style) .rotationEffect(.degrees(-90)) .frame(width: size.width, height: size.height) } .onAppear { DispatchQueue.main.asyncAfter(deadline: .now() + 1) { withAnimation(.easeInOut(duration: 1)) { progress = 0.75 } } } } } #Preview { ZStack { ProgressRingPrototype( progress: 0.1, size: CGSize(width: 256, height: 256), thickness: CGFloat(32), color: .primary ) ProgressRingPrototype( progress: 0.1, size: CGSize(width: 190, height: 190), thickness: CGFloat(32), color: .primary ) ProgressRingPrototype( progress: 0.1, size: CGSize(width: 124, height: 124), thickness: CGFloat(32), color: .primary ) } } Here's a snapshot of the live preview. I'm experiencing an issue where the trailing line cap generated by the stroke exceeds the start angle of the angular gradient, which creates an ugly artifact at 0 degrees. Anyone have a solution to this problem? Derek

unable to optimize App for iPad
I use swiftui to build apps on iPhone and iPad. There is no problem with the iPhone app. The game display is fully shown on iPhone. However, for the iPad, the game display is not shown and the screen goes black. I had to tap the button on the upper left side.(looks like a side view button) After that, the game display is only shown in the left side in a very small size. How can I make the game display fully shown in the iPad?

Xcode 26 Beta 3 – SwiftUI Previews & Project Window State Broken After Minor Edits?
Hi everyone, since updating to Xcode 26 Beta 3, I’m seeing some really strange behavior. I just changed the color of a Color asset in my SwiftUI view – literally just switched from one named color to another – and suddenly: • Previews stopped working completely, with vague or no error messages. • Even when I changed the color back to what it was before, the previews still refused to build. • In addition, Xcode no longer restores the open tabs/windows when reopening the project. It just shows a blank editor every time I open it. This all happened without touching any project settings or code structure – just a simple color swap. Has anyone else run into this with Xcode 26 Beta 3? Would love to know if it’s a known bug or if there’s a workaround (besides nuking Derived Data, which I’ve already tried). Thanks!

Set the ui resources for the face id page
I am developing an app that requires calling the iPhone's Face ID module to scan users' facial data. Where can I find Apple's design resources and guidelines for Face ID? The Face ID resources available in Figma are incomplete, and I need more support. For example, in the iPhone settings, the scenario: the UI interface for scanning the user's face to collect data, specifically the circular design in the "How to Set Up Face ID" screen.

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

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 :)

Testing In-App Purchases
Hi, I have a couple of questions in regards to testing in-app purchases. I tested the subscription on a device but I'm not sure how to reset so I can test again. I didn't see the subscription in device settings or in Debug -> StoreKit -> Manage Subscriptions window. Additionally, I was wondering if there was a way to detect the subscription being made. I implemented this, but I'm not sure if that will work: .onChange(of: Product.SubscriptionInfo.RenewalState.subscribed) { if Product.SubscriptionInfo.RenewalState.subscribed == .subscribed { } }

iOS 26 beta 3 bug report
In the clock app when making an alarm for myself to wake up, I found this bug where If you swipe left On an alarm without deleting it and then Swipe right it does a goofy visual glitch where it teleports to the top of your screen.
