Some SF Symbols (wifi for example) render fine with the variable. But many, mostly ones with the circle being variable, do not seem to work. The SF Symbols app shows them rendering with a variable fine. But in code it doesn't work. Am I missing something or is there a reason?
var body: some View {
HStack {
Image(systemName: "01.circle", variableValue: 0.5)
Image(systemName: "figure.wave.circle", variableValue: 0.5)
Image(systemName: "wifi", variableValue: 0.5)
}.font(.largeTitle)
}
}

Activity
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?
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:

Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.

This issue affects core system UI elements such as Control Center, notifications, and system apps. In iOS 26, the Liquid Glass UI introduces excessive transparency and blur across the system. This significantly reduces text readability, lowers contrast, and causes visual fatigue during prolonged use.
There is currently no true option to fully disable Liquid Glass effects. Existing accessibility settings only partially mitigate the issue and do not restore a solid, high-contrast interface similar to iOS 18.
Please consider adding a system-wide toggle to completely disable Liquid Glass and transparency effects, or provide a solid UI mode for users who prioritize readability and visual comfort.
This is especially important for accessibility, as the current design negatively impacts users sensitive to eye strain and low contrast.
Feedback for iPhone and iPad – Display Technology
Dear Apple Team,
Currently, the mainstream display technology used in iPhone and iPad is OLED. However, OLED panels produce significant PWM flickering, which strongly irritates the human eye. Many users, especially in China, experience eye strain, tearing, and discomfort after using OLED devices for a period of time.
There is a large group of users here who are highly sensitive to screen flicker and therefore cannot use OLED-based devices at all. What they truly need is an eye-friendly device with either LCD or flicker-free Mini-LED display technology.
I sincerely recommend that Apple consider offering iPhone and iPad models with LCD or Mini-LED panels. Such displays could provide better eye comfort, no flicker, and a healthier experience. Currently, almost no smartphone manufacturers in China provide such options, and even if they do, their devices often come with outdated chipsets and cannot be used as a reliable daily driver.
This presents a valuable opportunity for Apple: by addressing this demand, Apple could attract a unique customer base, increase sales, and even justify a slightly higher price, as many customers would be willing to pay more for the sake of their eye health. In the Chinese market, a truly flicker-free iPhone or iPad would be incredibly rare and highly desired.
Thank you for considering this suggestion. I truly hope Apple will take this into account.
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 am developing an app in Swift Playground (No Xcode). All my Views respond to the navigation call when I click NEXT except one. When I click NEXT the app hangs then crashes. The error message does not identify the cause of the crash. I have research every possible lead with no success. I would like to get some ideas on how to resolve this issue.
In Apple Music I opened fullscreen for a song and I accidentally clicked some keys and the name and artist name of the song I was playing disappeared, and I can't figure out how to get it back, it temporarily comes back when I hover over the top bar but I can not get it to stay there permanently.
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.
Dear Developer, Is there a way to create a function to search with inside a text without having to be outside all of the messages? In other words, could I go into one of my contact’s texts and then search specifically inside that message as can be done on Android? This would be such an amazing function And make life so much easier. Thank you.
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
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?
I’m not a developer - I’m just trying to find out where to post a question I have that might relate to iOS 26.
I'm using .glassEffect(.clear) on a transparent circle over a gradient background. While it's closer to clear than the plain glass effect, it't not really clear, like clear glass. Here is the code. Is there a glass effect that really looks like clear glass?
Circle()
.fill(.clear)
.frame(width: 180, height: 180)
.glassEffect(.clear)
I’m working with Reality Composer and noticed that images added directly to a scene appear significantly darker when viewed in AR.
This seems different from how other objects in the scene respond to lighting, especially under varying real-world light conditions.
Is this expected behavior?
Are images treated with a different lighting model in Reality Composer?
Is there any recommended way to get more consistent light response for image-based artworks?
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,
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")
}
}
}
}
I'm coding an iPhone app using Swift and I'm getting this scoping error. Attached.
Hi,
It would be sure if Apple creates a Fgima plug in to convert designs to SwiftUI, no one can do it like Apple and it would be SUPER and super time saving !
