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.

Hello, Our app rejected by following reason: Guideline 4.3 - Design We noticed your app shares a similar binary, metadata, and/or concept as apps previously submitted by a terminated Apple Developer Program account. Submitting similar or repackaged apps is a form of spam that creates clutter and makes it difficult for users to discover new apps. Next Steps Since we do not accept spam apps on the App Store, we encourage you to review your app concept and submit a unique app with distinct content and functionality. Resources Some factors that contribute to a spam rejection may include: Submitting an app with the same source code or assets as other apps already submitted to the App Store Creating and submitting multiple similar apps using a repackaged app template Purchasing an app template with problematic code from a third party Submitting several similar apps across multiple accounts Learn more about our requirements to prevent spam in App Store Review Guideline 4.3. iOS App 1.0App Version Rejection Reasons: 4.3.0 Design: Spam The application is 100% developed by our team and I am 100% sure of it. How can we do it ? Please help.

Hello! I am developing an ebook reader iOS app that uses c/c++ codec as a page renderer. The codec uses TrueType as a font rendering engine that requires access to .ttf (or .ttc) files. Currently, I supply TrueType with fonts embedded in the app package, so they lay within the app sandbox. The codec supports the whole unicode plane and many languages that ebooks may use, but the fonts I supply don't have some of the important glyphs (i.e. katakana or hangul). I see that iOS has its own font storage, located in /System/Library/Fonts/ directory. The codec is able to parse this directory and read .ttf files located inside, using these fonts as a fallback in the case when the supplied fonts can't draw certain glyphs. I use opendir and fopen(in "rb" mode) as a way to read the data, and it works well. Does this type of access to the system directory violate the sandbox rule for an app distribution, and, if yes, is there a way to get access to stored .ttf files not violating the mentioned rule?

Hi, I've been trying for an hour to turn the symbols in sf symbols from left to right to right to left, I'd appreciate some help

Hello there, I have a couple of question about Apple Pay guidelines: • if we offer Apple Pay payment method in our app, can we disable the selection (I mean the method selection NOT the Payment button!) IF certain condition happens? E.g. the user cannot select apple pay payment method because our basket is not ready yet. • Are we forced to move the apple pay payment method on the top of our selection? E.g. Cards, Cash On Delivery, Coupon, Apple Pay --> Apple Pay, Cards, Cash On Delivery, Coupon One last technical question: • when we start the payment process we are gonna create the request and present the sheet BUT we have to call our backend for pre-authorization, is it allowed? @objc private func applePayButtonTapped(sender: UIButton) { // TODO: Is it allowed? // We need to ask to our backend a pre-authorization and THEN procced with Apple Pay flow // but this could be done ONLY after the user TAP on BUY with APPLE PAY and BEFORE // paymentAuthorizationViewController is called. // Are we compliant to do that? if PKPaymentAuthorizationViewController.canMakePayments(usingNetworks: FakeData.paymentInfo()) { let request = PKPaymentRequest() request.blablabla = blabla let authorizationViewController = PKPaymentAuthorizationViewController(paymentRequest: request) if let viewController = authorizationViewController { viewController.delegate = self present(viewController, animated: true, completion: nil) } } } Thanks in advance :)

My app lets users create things with text, and I've included Apple fonts so users can format their text with them. These were fonts I found in the Font Book app that comes with macOS. My assumption is that these, like the San Francisco font, can be distributed with apps. Do I need to attribute these fonts to their creators and publish a license in my "About" page? If so, where do I find the license(s) and what is the proper way of publishing them? Is there anything else I should know? Please let me know if this should've been posted under a different topic and tag

This is a follow-up to my previous question: How to attribute/credit Apple Fonts added to app? In that previous post, I misremembered what I did and said I found fonts via macOS' FontBooks, when instead I came acrossUIFont.familyNames. Since these are included via UIKit, the legal implications should be different. I looked at various license agreements that govern iOS app development but haven't found anything mentioning fonts. Since these are included as part of UIKit, its reasonable to assume that developers are allowed to include these fonts--but in what ways? Am I allowed to let users create, say, documents with these fonts? Am I only allowed to display these fonts? There are 84 fonts, and judging by their FontBook entries, there is a wide range of licenses and restrictions. It seems unnecessarily harsh to have every iOS developer verify each one and figure out which they can legally keep if they want to offer their users access to all (for, say, a text-editing app). There must be some overarching rule that supersedes/encapsulates them, but this rule isn't clear to me after hours of research. I'm not a lawyer, and I don't think Apple expects every app developer to consult their lawyers on whether they can use system fonts. I'm about to send an email to Apple's legal team (I will post their response here if allowed), but in the meantime I want to hear what other devs think about this. In Xcode, entering UIFont.familyNames returns the following: ["Academy Engraved LET", "Al Nile", "American Typewriter", "Apple Color Emoji", "Apple SD Gothic Neo", "Apple Symbols", "Arial", "Arial Hebrew", "Arial Rounded MT Bold", "Avenir", "Avenir Next", "Avenir Next Condensed", "Baskerville", "Bodoni 72", "Bodoni 72 Oldstyle", "Bodoni 72 Smallcaps", "Bodoni Ornaments", "Bradley Hand", "Chalkboard SE", "Chalkduster", "Charter", "Cochin", "Copperplate", "Courier New", "Damascus", "Devanagari Sangam MN", "Didot", "DIN Alternate", "DIN Condensed", "Euphemia UCAS", "Farah", "Futura", "Galvji", "Geeza Pro", "Georgia", "Gill Sans", "Grantha Sangam MN", "Helvetica", "Helvetica Neue", "Hiragino Maru Gothic ProN", "Hiragino Mincho ProN", "Hiragino Sans", "Hoefler Text", "Impact", "Kailasa", "Kefa", "Khmer Sangam MN", "Kohinoor Bangla", "Kohinoor Devanagari", "Kohinoor Gujarati", "Kohinoor Telugu", "Lao Sangam MN", "Malayalam Sangam MN", "Marker Felt", "Menlo", "Mishafi", "Mukta Mahee", "Myanmar Sangam MN", "Noteworthy", "Noto Nastaliq Urdu", "Noto Sans Kannada", "Noto Sans Myanmar", "Noto Sans Oriya", "Optima", "Palatino", "Papyrus", "Party LET", "PingFang HK", "PingFang SC", "PingFang TC", "Rockwell", "Savoye LET", "Sinhala Sangam MN", "Snell Roundhand", "STIX Two Math", "STIX Two Text", "Symbol", "Tamil Sangam MN", "Thonburi", "Times New Roman", "Trebuchet MS", "Verdana", "Zapf Dingbats", "Zapfino"]

Hello, I noticed a small mistake in the Human Interface Guidelines (HIG). On the page HIG > Components > System Experiences > Widget > watchOS Widget Dimensions, scroll down to the bottom. In the "watchOS widget dimensions" section, the sizes in the table are in pixels (px), not points (pt) actually. However, the table header indicates the sizes should be in points (pt). Page link: https://developer.apple.com/design/human-interface-guidelines/widgets#watchOS-widget-dimensions For example, the widget size in the Smart Stack on a 49mm watch should be 192x81.5 pt (or 382x163 px), not 382x163 pt. This size can be verified with the information provided here: https://developer.apple.com/documentation/watchos-apps/supporting-multiple-watch-sizes/. https://developer.apple.com/documentation/watchkit/wkinterfacedevice/1620974-screenscale

Video Playback on iOS 18 public release is asinine. I use video playback to show slow-motion video frame by frame to my students and the video can only be shown at like 3/5 of the screen size (just like Apple fouled up screenshot editing about a year ago) If you try to view video in the full screen you can’t scrub through and see time stamps or play frame by frame sliding left to right. It’s absolutely ridiculous. 2 out of 3x the video timeline finishes fully right and I haven’t watched the full clip. Here’s a video showing the issue how at the small default size I can see the entire timeline and play the full video from beginning to end, but when I go to full screen and/or zoom in or move the screen around the timeline doesn’t work and you can’t scroll through the full video! Need the video to not condense in size on the screen and play the full height / width of the screen. Also not have the text of the location showing above the screen. Way too much clutter. The reduced size of the video for editing issue started with photos several updates ago and now Apple idiotically brought a terrible flaw from photos to videos as well. Ugh.

The following icon has been introduced in Safari's address bar for iOS 18: I’d like to use it in my app to guide users on how to enable my Safari extension, but I couldn’t find it in SF Symbols beta 6.0 (99). Is this because it’s still in beta and will be available for third-party use later, or is it a private icon that only Apple can use? I hope I just overlooked something.

Bonjour, Je me permet d'écrire un message car je rencontre un souci avec la vue canvas j'ai le message d'erreur suivant " CrashReportError: XCPreviewAgent crashed because Adjust.framework is missing" je ne sais pas trop comment identifié le problème j'utilise pod En vous remerciant par avance

Hi,After I tried to submit my APP for review several times, it was still rejected for the following reasons: Guideline 4.1-Design-Copycats: The app or its metadata appears to contain potentially misleading content. Specifically, the app includes content that resembles ODIKING without the necessary authorization. But odiking belongs to our company's product, I don't know the problem, I don't understand how to prove that this product does not belong to a third party content Tanks1

Hi there, I'm working on a product which needs to pair with an iOS device (only iPad and iPhone) via Bluetooth. I already have the device pairing and operating fully with android or Windows hosts and have implemented BLE. Obviously, iOS isn't as simple as those for pairing. The product type is not listed under the MFi accessories. The question I have is what hardware and or firmware needs does the product needs to fulfil in order to pair/bond fully. I've seen some devices have a MFi security chip, some need to be manufactured in a MFi approved facility, I've no idea on the firmware requirements. We're starting the process of joining the MFi program too. So: Do I need the security chip? Where is the pairing process documented? Can I use BLE or do I need to use classic Bluetooth or core Bluetooth? Any help would be greatly appreciated because I'm kind of lost. Thanks, Louis

In Carplay, is it possible to update the navigation title and also add right tab bar items? Couldn't find these details in the documentation. Please suggest

Hi, starting from iOS18, it is impossible to differentiate between completed meetings and future meetings in calendar - almost the same color (unless I switch to dark mode). Is there a way to fix it or is it a human engineering bug?

I'm trying to download version 2.1 of SF symbols even though version 6 is out because I have a older macOS but I can't find it. So, how would I work around this?

Hello, I am an app developer from China. We are developing a mobile game that will be released on iOS and Android platforms (as well as some PC and Mac platforms). The game is a commercial app. My question is: we would like to use the "PingFang" Chinese font in our game software. Do we need to obtain a license, and how should we go about obtaining it? (For example, through which channels should we apply for the license, and what are the associated fees?)

Hello everyone, I'm developing an app using RoomPlan where users can capture several rooms individually and assign custom names to each room. When I merge these captured rooms into a single CapturedStructure using the StructureBuilder, I want the merged structure to retain the original sections with their custom labels. However, I'm encountering an issue: Problem: After merging, the CapturedStructure's sections have different identifiers (UUIDs) compared to the original sections in the individual CapturedRooms. This means there's no straightforward way to map the custom labels from the original rooms to the sections in the merged structure. What I've Tried: Mapping by Identifiers: Attempted to map custom labels using the sections' identifiers, but the identifiers change during the merge, making this ineffective. Mapping by Positions: Tried matching sections based on their center positions (simd_float3), but these change. Modifying Section Labels: Considered changing the label property of the sections before merging, but the label is read-only and cannot be modified directly, and the CoreModel is used for merging rather than the data that can be modified via json. Question: Is there a recommended way to preserve or map custom section labels when merging multiple CapturedRooms into a single CapturedStructure using RoomPlan? How can I ensure that the custom labels assigned to rooms before the merge are correctly associated with the corresponding sections after the merge? Any guidance or suggestions would be greatly appreciated! Thank you!

When using a double-tap primary action on a button, there will be a 1 second delay before the action is executed after the double-click is detected. Why is the design not like scrollview, which executes actions after double-tap detection? Is there a way to make the button perform an action after detecting a double-tap?

Hello, I am currently creating a component in swiftUI and I would like on xcode to be able to select the elements individually with the selector button on the xcode preview on the canva but when I click on an element it selects all the iphone and not the element individually how can I do this please?

Hi, I'm trying to create a visualization using charts for vision pro. I want to create a line chart that connects pair of points on a donut chart. So i'm trying to draw the lines radially but it seems that the line chart always has only the bottom left corner of the view as origin. How can I tranform the origin to center of the view?
