Avoid using a segmented control in a toolbar
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: Source 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.

New in SF Symbols 7: ipod.and.vision.pro.
Why? Why stop there? (Why not ipod.and.imacg3? applenewton.and.vision.pro?) I get why the older ipod symbols exist but these new pairings are odd. If anyone ever sees these restricted symbols in the wild, or even just someone using a Vision Pro and an iPod (Touch) together in a way that's not contrived, please do let me know!

How to get a truly clear glass effect for a circle
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)

Repost : Analog Clock on lock screen
When we are going to have a real analog clock option on the lock screen. If an apple watch can do it surely its not that difficult. For someone who uses a clock to tell what time it isn't as opposed to what time it is, i’m constantly having to convert a digital image where the image of hands on a dial is so much easier. Surely this isnt because someone has forgotten how to read a clock

Cloudkit only syncs when app is reloaded.
I've seen a few older posts claiming the same behavior I'm seeing which is my cloudkit/core data app only syncs to iOS when the iOS app is reloaded. Can someone clarify if this is a bug, or the expected behavior. I have an iOS app which the entire purpose of it is to view synced data from MacOS, and I have a refresh button which does nothing because the data only syncs when the app is closed and reopened. Am I supposed to tell users to close and reopen the app to see fresh data? that seems like a terrible UI behavior, and I know apple does not accept this as all of their apps sync without needing to be reloaded. For example the notes app does not need to be reloaded for the MacOS -> iOS data to be synced.

glassEffect() in SwiftUI always renders as white
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 26 Beta 2 (Tahoe) • Xcode 26 Beta 2 • Samsung Odyssey G9 57” monitor (super ultrawide) • Using Preview in SwiftUI, I use IOS 26 Beta 2 (not the Simulator) Even when I use Apple’s default demo code like: Text("Hello World") .padding() .glassEffect()

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.

iPad screen size
Hi, Does the iPad Playgrounds app act completely the same way as a MacBook Playground? I am developing my app on a 2020 MacBook Air M1 using Swift Playgrounds. However, since the testing is going to be done on an iPad Swift Playgrounds, I was worried if my playground would work, since it relies heavily on the screen size etc. My app runs completely perfect on MacBook Playrgounds, but doesn't work on the iPad simulator on Xcode.

Spam 4.3 (a)
Hello everyone, I’ve reached out to Apple’s review team multiple times, but unfortunately, I haven’t received any clear or specific guidance on why my app was rejected. My app has been rejected several times with the reason “Spam” under guideline 4.3, and I still don't understand exactly which part of the app is problematic. Even after providing the necessary information about the data, I resubmitted the app, and after a few days, it quickly moved into "In Review" status, but then was rejected within seconds with the same “Spam” message. I have sent over 13 messages asking for specific feedback, and all I get are vague responses saying “It’s spam, refer to 4.3, fix your app, and resubmit.” However, when I review the guidelines, I don’t see any specific reasons for rejection that apply to my app. I’m particularly confused because my app is a VPN, and when I check the guidelines, I see that apps in categories like dating and others are saturated, but VPN apps are not. My app uses completely dedicated servers, and the IP addresses are not found in any other apps. Still, my app keeps getting rejected. If anyone has encountered a similar issue or has any insight into what might be causing this, I would greatly appreciate it if you could provide detailed guidance on what specifically needs to be changed to get the app approved. Thank you!

Liquid Glass App Icons without Icon Composer
We have found that on iOS 26 beta some of our app icons built from an Xcode 16 asset catalog containing a single 1024x1024 .png file have a Liquid Glass effect applied to them while others have not. The documentation states that If you choose not to use Icon Composer, you can still use an AppIcon asset catalog in your project containing individual app icon images and let the system apply the Liquid Glass material. and If you prefer, you can take advantage of the system’s automatically generated treatment that is applied to all app icons. Is there any insight into how the system treats app icons that have not yet been updated with Icon Composer?

Navigation Bar Title Hidden When Right Bar Button Title Is Long (iOS 26)
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?

Layer to SVG script
In the video ”Create Icons with Icon Composer”, the presenter mentions that Apple has created a layer-to-SVG script for Illustrator that‘s available for download: Once the artwork is in a good place, next we want to export the layers as SVGs. For every tool, this can look a bit different. For those using Illustrator, we've created a layer to SVG script that will automate this for you, which you can download. Exporting out the canvas size ensures everything drops right into position in Icon Composer. Here‘s the link to the mention: https://developer.apple.com/videos/play/wwdc2025/361/?time=377 I can’t find any place to get this script, and my designer is very interested in using it to import our Illustrator icon into Icon Composer. Can someone point me to it?

Liquid Glass is not just decoration it is the soul of iOS 26
As someone who genuinely appreciated the Liquid Glass effect introduced in iOS 26 Beta 1–2, I am deeply disappointed by its reduction in Beta 3. Liquid Glass wasn’t just eye candy it gave iOS a unique identity, futuristic feel, and a visual soul. Now, the UI looks flat, generic, and indistinguishable from other platforms. I feel Apple is stepping back from a bold vision due to readability complaints that could’ve been solved with an option or toggle not by removing the whole design language. Please consider restoring the full Liquid Glass look, or at least offer a toggle so users who believe in Apple’s design language can choose it. Don’t let this innovation fade because of short-term complaints.
