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?

In macOS 26 Betas 1–3, the system applied an automatic dark-mode fallback for app icons. This ensured consistency across the Dock and Finder even when developers hadn’t provided dark assets.
Since Beta 4, this fallback was removed. As of Beta 7, icons now rely entirely on developer-updated assets. The result is mixed light and dark icons in the Dock, breaking visual consistency and making app recognition slower in dark mode.
Observed behavior:
• Icons without dark assets are displayed in their original light version.
• Some apps (e.g. Final Cut Pro) show a gray border treatment that feels inconsistent with the rest of the UI.
• The fallback applied in Betas 1–3 is completely absent.
Expected behavior:
System should provide a fallback rendering until developers supply proper dark assets, or offer a toggle in System Settings → Appearance (e.g. “Force Dark Icons”).
This is still present in Beta 7. Is there any plan to restore the fallback mechanism or provide a user option?
Hi,
I want to generate some sample datas for demonstrating the functions of my app when the app launched. My codes are as followings:
func generateSampleData() {
let hasLaunchedKey = "HasLaunchedBefore"
let defaults = UserDefaults.standard
if !defaults.bool(forKey: hasLaunchedKey) {
//generate the demo data
}
defaults.set(true, forKey: hasLaunchedKey)
}
And I put the func in a view's onAppear modifier. I found every time I go the view, it generates the demo data again, which results in producing a lot of demo data. But I have set the status of the function running in the userdefault. Why did it happen?
Best Wishes,
Hi there. Our designer is designing our app in Figma with the navigation element with compact size navigation bar, and large title. I couldn't find an API to actually configure the nav bar to be compact while keeping the large title enabled. Figma uses the libraries provided by Apple so it's weird I can't find such configuration in iOS26.
I'm adding a screenshot of the options in Figma.
First option is: Large size & large text.
The one our designer is using is compact size & large text.
I have an ongoing activity in progress.
Think of:
a delivery in progress
house internet reboot in progress
some water / electricity / internet / tv outage.
(food) order processing
I want to show a persistent toast message above the tab bar, across all tabs and screens across the app. It could take 15 minutes until the activity is finished.
Obviously there's a challenge of:
accessibility
content overlaying with each other
extra engineering effort.
What we've thought of doing is:
Option1: show a toast message, but when a modal is presented then it presents on top of the toast message. The toast message no longer updates itself. Once the modal is finished, then the toast message re-appears and continues to update.
Option2: keep the toast message across all tabs and modals and work through the challenges mentioned
Question:
What are some other design approaches that could be taken to persist an ongoing activity (much like 'Live Activity', but just across the app when it's in foreground) or what are some design reasons that the two options considered are bad?
Hello everyone,
I'm very impressed with the Liquid Glass design introduced in iOS 26, especially how native app icons automatically adapt to the system's display mode (dark or light).
This brings me to a question: Is it possible to make a website shortcut icon created via Safari's "Add to Home Screen" feature adapt to Dark Mode in the same way?
For native apps, we can use tools like Icon Composer and asset catalogs (Assets.xcassets) to provide different icons for each mode. It would be a huge improvement for web clips if we could achieve the same with existing web technologies like apple-touch-icon or the Web App Manifest.
If anyone has figured out a way to do this, I would greatly appreciate it if you could share your knowledge.
Thanks in advance!

iOS 26から導入されたLiquid Glassデザインについて。
ネイティブアプリのアイコンがシステムの表示モード(ダークモード/ライトモード)に合わせて自動で最適化されるようになりました。
そこで疑問に思ったのですが、Safariから「ホーム画面に追加」機能を使って作成するWebサイトのショートカットアイコンは、ネイティブアプリと同じようにダークモードに対応できないのでしょうか?
ネイティブアプリの場合は、Icon Composerなどのツールでアセットカタログ(Assets.xcassets)を使い、モードごとのアイコンを用意できますよね。
Web側でも、apple-touch-iconやWeb App Manifestといった既存の仕組みを使って、アイコンを動的に切り替えられるようになると、Webクリップの使い勝手がさらに向上すると思うのですが
もし、すでに何らかの方法で対応されている方がいらっしゃれば、ぜひその知見を共有していただけると嬉しいです。
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.
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:

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.
Can the vehicle‑side UWB module, acting as a Nearby Accessory, perform ranging with multiple iOS phones simultaneously while iOS cell uses background ranging with the vehicle‑side UWB (which involves BLE GATT services)?
I mean, when the IOS cell works in the background, it will read the nearby gatt characteristic automatically. If there were multiple phones perform ranging with the accessory, the read characteristic from the accessory side, what shall its content be?
Or does the accessory only perform ranging with one phone at a time?
Hello Apple Developers i am here write down my experience with the IOS 26 Beta
first off i would like to say that i kind of do/don't like the new iquid glass UI/UIX Designs in some parrts of the ios like in m ust 3rd Party Apps like Uber Lyrith MJ Access Link Moblie app DoorDash VLC And Apple Music App just to name of few
since i have installed the beta i have ran into a few bugs i have alread sent to the feeback app via iphone but i'm going to write them here as will i'm not looking for troubleshoots or tech support i'm just shareing my experience with the apple community and the Apple Development/Enginer Team to fine tone for release Time
please note that i am a user with Vision impairment so please by respect to me due to my writteing issues and grammer and spelling
so here i go my first bug that i ran into on the first day was when i was listening to some music trakcs in the apple muisc app when scrolling down or up fast the app will froze for mill secend then contiune as noraml
my second bug that i ran into dureing music play was with my Crossfade settings not working on some tracks im not sure if this is due to BMP alignment or AI algorithm integration with in the software itseif but for me this takes me out of the listening experince that i have when i enjoy listening to music
My suggestion Move the AutoMix and Crossfade Settings in to the Apple Music its seif and give the user more controll over how long or how short they want the crossfade or autmix to happen dureing the ending of each tracked play also for the cross fade option is set at 12 increase this to 30 secs or more if possiable or add an BPM options for the Automix to mix in the next track via BMP for simple of my rock track is at 148 BMP the next track should be pop or kpop or rap synceing up with that same BMP speed or similar at 148 BMP my next suggestion for the Apple Music App Shameless track mode (this mode to can be Incorporated) in to the Automix Featrue this redue some music tracks that ends abruptly some MP3 tracks added outside of the Apple Music App seems to broke dureing playback
My 3rd bug that i ran in to with the Glass UI for controll Center like i stated before i am Vision impaired with the clear Glass over lapping the current UI for me this hard for me to tell what icons i am looking atside from the Voolum and Brightness Bars i am asking please make this more dark theme and make the icons brigher or add name undernearth the icons or Flip the Dark them or dan the current UI over lapping the Controlor center or add White colors with Black Arrows/icons for all Apple App that has this Glass UI in side of cause this is driving me nuts
My 4th Bug that i ran into was with the lock screen/restart/reboot ohh girl where do i began with this one let's with the notifications i don't know who through it was a good idea to have a Clear Bright UI over lapping the Notifications this is very annoying via imessage Texting cause my custom wallpaper Blends in with a white background and this is Worst
My suggestion for this is very simple darkering the background on the lock screen abit more so the text is more reader or increase the Notification bars (this is for users like myseif that use Dark mode)
My 5th Bug involves my Back ups/Restore/Corrupated < is seif explanatory when i tryed to downgrand back to Version 18.5/18.6 nothing happened so please fix this or make it a bit more easyer for users to be able to back up/Retore their Devices now i has to wait until (Tomttow morning Friday) to factory reset my phone
my conclusion since Beta Users and Developers and Engiers are Still testing please take look at my suggestion and try to bring not all but some of them in to public Release
Thank You!
Update i would like to Downgrad from IOS 26 Developer Beta back to IOS 18.5
Does iOS 26 support HDR images for app icons to be rendered in High Dynamic Range for Springboard or not?
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?

I’m developing an app that includes a navigation bar with a centered title and a single right bar button item. I’ve noticed that when both the navigation bar title and the right bar button item’s title are relatively long, the navigation bar title becomes hidden.
This issue only occurs on iOS 26. When running the same code on iOS 18, the layout behaves as expected, with both elements visible.
Has anyone else experienced this behavior on iOS 26? Is this a known layout change or a possible bug?
Hi everyone,
We noticed a readability issue with the CallKit incoming call UI on the lock screen in iOS 26.
In our case, the “slide to answer” text appears too faint and unclear, making it difficult to read. The arrow button is visible, but the text itself has very low contrast against the background, especially on certain wallpapers or under lower brightness conditions.
From the screenshot, you can see that:
the caller name is clear,
the overall incoming call UI is shown correctly,
but the “slide to answer” label is barely visible.
This seems to be a system UI / CallKit presentation issue rather than something controlled by the app, since we are using the standard CallKit incoming call flow.
We would like to know:
Has anyone else seen this issue on iOS 26?
Is this considered a known UI regression or contrast issue in the new system design?
Is there any supported way to improve the visibility of this text, or is it fully managed by the system?
Any confirmation or related reports would be very helpful.
Thanks.
Hello everyone,
In the current iOS version, changes in the "liquid glass" light shining effects can repeatedly be observed on older iPhone devices (12/13/14).
This change is often seen after the device is rebooted or after a SystemMemoryReset.ips (System Analysis Data).
It changes very often...
I'm not currently working on apps myself, but perhaps someone has ideas for the upcoming updates involving Liquid Glass.
(please also check the screenshots)
I'm using a NavigationSplitView on macOS which needs to show 2 or 3 columns depending on the selection of the sidebar.
Column 1 has a list of main activities. Some of these just have some data to show and some have a sublist.
Currently, when an item that has no sublist is selected, I set the 2nd column (content:) to:
Spacer()
.navigationSplitViewColumnWidth(0)
This works, although it started hitting bugs requiring a workaround on macOS 26, which got me wondering, what is the correct approach here?
NavigationSplitViewVisibility.doubleColumn is not the solution, as this hides column 1, not column 2.

Hi everyone, I'm new to building apps on Swift and recently I've been wondering how does Apple get this blur effect behind the control center on Mac OS Tahoe. I think it would be nice to use in an app that I'm making but I can't seem to find it in the docs. Is it available through AppKit? I would appreciate some help on this
I’m currently using the iOS 26 Developer Beta and noticed the new icon design for the Camera app. Personally, I preferred the previous icon it looked cleaner, more elegant, and felt more in line with Apple’s signature iOS design language.
The new icon feels more like something you’d expect from Android. It lacks the minimalist, refined style that usually defines iOS icons. I understand UI evolves over time, but this change feels like a step away from what makes Apple’s design philosophy unique.
Just wanted to share this honest feedback as a long-time user and developer. Thanks for considering!
I'm looking for a way to display a notification badge without showing a number—essentially, just an empty badge to indicate the presence of notifications. From my research, it seems like this functionality isn't available . Is there any workaround or method to achieve this?
