Here is my code and the error code being generated during build.
let myString : String = "https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=AAPL&apikey= D5GY7HKODE66G0T9"
var banjo = URL(string: myString)
let task = URLSession.shared.dataTask(with:banjo ) { myDatastring , response , error in}
// task.resume()
I've tested that URL in my browser and it works. But when I try to build I get: Value of optional type 'URL?' must be unwrapped to a value of type 'URL'
Please tell me what I'm doing wrong. I think the URL struct is not returning a URL type of object.

Is it possible to use the new variable draw feature for a custom SF Symbol without it leaving the background behind it when it is not drawn?
I am trying to make a tally icon that is drawn with the variable draw, but it doesn't look good if the tally is visible in the background before it is drawn.
Hi, I'm getting started with designing and coding a watchOS app. I wanted to use Sketch to plan the UI before I dive into coding, but it seems like the official Sketch templates on the Design Resources page only have templates for the Series 8 and SE 2 on watchOS 10. I want to use the Series 10's screen size for my layouts since it's the model I have, but I can't find a template for it. Will the official templates be updated for the new models? If not, does anyone know of a third-party template I can use? Thanks in advance!
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
Development environment:
Simulator: iOS 26 beta 3 iPhone 16 (for testing)
Simulator 2: iPadOS 26 beta 3 iPad Air 13 inch (M3) (for testing)
Connected Device: iPadOS 26 beta 3 iPad Pro 11 inch (M4) (for testing)
Dev Device: macOS Tahoe 26 beta 3 Macbook Air
When using the NavigationSplitView element, the sidebar has a built-in panel toggle button.
However, when I click the toggle button to toggle the sidebar section in SwiftUI 26 on both simulator 2 and the connected device, it has a slight animation glitch before going back to normal. What's going on?
This is my code for the specific view that has the NavigationSplitView (and all views are connected through TabViews):
RecordsPage.swift
Here are image references:
When I clicked the toggle:
After 1~2 seconds:
These images are in the state of the panel being hidden.
Does iOS 26 support HDR images for app icons to be rendered in High Dynamic Range for Springboard or not?
Hi everyone,
I’m having trouble getting the new glassEffect() modifier to render correctly in SwiftUI.
No matter what I try, it just appears as a solid white background (instead of translucent glass). This happens both in Beta 1 and Beta 2.
My setup:
• Mac mini (M4 chip)
• macOS 15 Beta 2 (Tahoe)
• Xcode 16 Beta 2
• Samsung Odyssey G9 57” monitor (super ultrawide)
• Using Preview in SwiftUI (not the Simulator)
Even when I use Apple’s default demo code like:
Text("Hello World")
.padding()
.glassEffect()
I see the logo all over the internet, but the only Official logo I can find is the swift logo, the orange one, but the blue one I do not see a place to download it nor the usage guidelines. I have seen it on various Icon site like Icon8. I would like to use it on my reddit forum that is dedicated to SwiftUI but I want to be legal. Is it allowed to use and if so, where can you download the official verison?
I had, a long time ago (over 10 years) developed an application that is connected to my UPS (for solar panels).
Until yet it worked very well, and I didnot have to compute more than making updates of XCode. That was all.
But yet I have swiched to the latest value of switch, and it continue to compile, but it does'not work. I am asking to yo in order keeping my app working as previously. As it does not work, which library is replacing Cloudkit.framework ?
and which library is replacing InsPersistantContainer.framework ?
Have a good day

When receiving or dialing a call, the green (answer) and red (decline) icons appear blurry, and there is a black screen overlay around the icons. This makes it difficult to interact with the call interface properly.
As a very exclusive Apple only I want to share my thoughts on the new iOS 26 update, which I recently installed on my iPhone 16. While I genuinely appreciate Apple’s drive for innovation and personalization, this update introduces visual and stylistic changes that, in my opinion, compromise what has made iOS feel uniquely Apple for so long.
Liquid Glass & Home Screen Aesthetics:
When I first saw previews of the “Liquid Glass” design, I was excited. I assumed it would add more flexibility to things like the home screen customization — something like an optional effect that builds on the popular app tinting feature introduced in the previous iOS version. But instead, it appears that the Liquid Glass look is now the default and, more concerningly, unavoidable.
The result is a visual experience that feels dramatically more bubbly and less refined. App icons appear more rounded and inflated in a way that — and I say this as constructively as I can — reminds me more of Android or Samsung’s One UI than of Apple’s signature design language. For someone who’s chosen Apple specifically because of its clean, crisp, and elegant UI, this shift is disappointing. iOS has always felt visually mature and thoughtfully minimal. With this update, it starts to feel overly stylized and visually heavy, which I don’t associate with Apple’s identity.
Camera App – Icon Design:
While I don’t have major concerns with the layout of the Camera app itself, the new Camera app icon is something I feel very strongly about. The previous design was balanced, clear, and professional — instantly recognizable. The new icon, is completely different, and it has more the camera that look like the actual iPhone camera, which I can respect the want to identify the app the iPhone. But this is not the effect I felt it has, I feel like it is less professional than before, which again makes me think a little bit about androids. This minor change feels bit because icons are what we see every day, and this one doesn’t feel quite right for Apple.
Along with the new camera icon, the other new icons like the notes app, and the slight change in the message app icon, these small shifts aren’t ones I was overly pleased with, kind of felt like something that wasn’t broke and didn’t need fixed
Messages App:
The Messages app is where I felt the biggest disconnect. The updated keyboard with the “keys” looking more bubbly which again, makes me think android. And with the new monogram icons (initials in thick fonts with purple backgrounds), make the app feel — again — much more like an Android UI. While that might sound superficial, it doesn’t make me feel like it’s an iPhone.
As someone who’s always preferred the Apple system, I’ve come to expect a particular standard of visual design — one that’s distinct from other platforms. This new look blurs that line. The once refined look of Messages is not as clean and simple as it used to be. I also preferred the gray background for monogram icons. The new colors and heavy fonts draw attention in ways that don’t feel as clean and simplistic which I have loved Apple for in the past.
Control Center:
Another area where I noticed a slight change is the Control Center. It’s not a big difference to the previous one, which I liked. The main difference I noticed was the brightness and sounds “bar” seems more elongated. Not a major difference but I would rather see the older design if I were to be honest.
What I Did Like:
There are some positives: I think the new lock screen notification styling works well, and the Liquid Glass effect looks great in that specific context. I actually really like the looks that it has with the notifications on the lock screen, having it be that transparent gives a clean and simple look. Lots of the new things that can be done in this update are very nice and convent, the more customization is great.
Final Thoughts:
To be clear, I offer this feedback not because I’m resisting change, but because I value what makes iOS feel like iOS. This update, while visually bold, feels like a departure from Apple’s strengths — the clean and simplistic look. If there’s one big takeaway I hope you’ll consider, some of the new looks that have been put in place give a feeling that’s not Apple, and more Android. it’s that many of these new visual styles would be better received as optional customizations, not system-wide defaults.
I would love to see an update to help fix some of this. I don’t believe there is a way to “un-update” my phone but if I could I would, even though some of these new things do look and feel good.
I'm developing an iPadOS 18+ application that uses a UITabBarController, styled as a sidebar, to serve as the primary navigation interface. This setup includes 20 different tabs, each representing a distinct section of the app.
For the user experience, each tab needs to present a master-detail interface, implemented using a UISplitViewController. The goal is to allow users to navigate between tabs via the sidebar, and within each tab, access related content through the split view's list-detail pattern.
The Problem:
Currently, my implementation involves instantiating a separate UISplitViewController for each tab, resulting in 20 unique split view instances embedded inside the UITabBarController. While this works functionally, it leads to significant memory usage, especially after the user opens each tab at least once. The accumulation of all these instantiated view controllers in memory eventually causes performance degradation or even memory warnings/crashes on lower-end iPads.
The Question:
What is the best approach to implement this type of architecture without running into memory management issues?
Specifically:
Is there a way to reuse or lazily load the UISplitViewController instances only when needed?
Can we unload or release split view controllers that haven't been used for a while to reduce memory pressure?
Would a custom container controller be more appropriate than using UITabBarController in this case?
Are there iPadOS 18+ best practices or newer APIs that support this kind of complex multi-tab, multi-split-view structure efficiently?
Any advice on how to optimize memory usage while preserving the sidebar navigation and split view layout would be highly appreciated.
I am struggling with exactly how to set up SwiftData relationships, beyond the single relationship model...
Let's say I have a school. Each school offers a set of classes. Each class is taught by one teacher and attended by several students. Teachers may teach more than one class, but only at one school. Similarly students may attend more than one class, but only at one school. Classes themselves may be offered at more than one school.
Can someone create a class for School, SchoolClass, Teacher, and Student with id, name, and relationships... I have tried it unsuccessfully about 10 different ways at this point.
My most recent is below... I am struggling getting beyond a school listing in the app, and I'll cross that bridge next. I am just wondering if all the trouble I am having is because I am not smart with the class definitions. And wondering if this is to complex for SwiftData and CoreData is the requirement.
This is not a real app, just my way of really trying to get a handle on Swift Data models and Navigation.
I am very new to Swift, and will take any and all suggestions with enthusiasm! Thanks for taking the time.

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
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 {
}
}
Target: MacOS 11.1 and above
C++, Juce 8, XCode 16.2
Testing: Sonoma 14.5
Logic Pro (latest version), Reaper 7.34, Pro Tools 2023.12 and 2025.6
I'm developing an audio plugin that creates an NSStatusItem ("menu bar status icon" or MBSI for short) to provide visual feedback for one of the components. I've encountered a Logic Pro-specific behavior that I'd like to fix. I'm building for Mac-only, Intel and Silicon, and for AU/VST3/AAX.
Summary:
The NSStatusItem for the MBSI is created successfully and functions properly in some hosts (Reaper (AU and VST3), Pro Tools (AAX)) but isn't visible in Logic Pro, despite identical API behavior.
Details:
NSStatusItem Creation: implementation using [[NSStatusBar systemStatusBar] statusItemWithLength:NSSquareStatusItemLength]
All API calls report success in both working (Reaper) and non-working (Logic Pro) hosts.
Logging shows Logic Pro and Reaper create the NSStatusItem with the same properties:
Window frame: {{0, -36}, {38, 36}} (both hosts)
statusItem.visible: YES (both hosts)
Button exists and responds to state changes (both hosts)
Y coordinate is -36 pixels (above visible screen, both hosts)
In Reaper, I can see the MBSI but in Logic Pro I can't. Note: the MBSI has no functionality beyond visual feedback. It's not clickable nor does it create a corresponding menu.
Questions:
Are there known differences in how Logic Pro's AU hosting service handles system UI elements compared to other hosts? And if so, is there guidance on AU plugins accessing system UI elements like the menu bar?

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)

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.
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.
I couldn't help noticing that the Maps and Find My apps make extensive use of "sheets stacked on top of each other" to represent its navigation hierarchy, with a "new content comes in from the bottom" orientation instead of a navigation stack with
"new content comes in from the right side" oriented transitions.
I'm interested in this topic because I have a similar navigation-hierarchy-over-a-map case in my app (with a custom map view though) and I'm torn back and forth between the approach of replicating the "stacked sheets" vs. putting a navigation stack in a sheet, esp. with the navstack approach being way more attainable with the iOS 26 glass design.
I couldn't find any guidance for this kind of UI in the Human Interface Guidelines; I'm leaning towards the navstack-approach for my app; but in terms of the behavior of the SwiftUI container views in this scenario it seems a little bit of an uphill path.
Any thoughts on what pattern should be preferred for presenting a deep navigational hierarchy on top of a map-like view?
