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?

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.
Hi Apple team,
We're planning to integrate Tap to Pay on iPhone feature in our product, and found there's a QR code button on the your Figma design: https://www.figma.com/design/2SOXmeLvimllvT67MTMLOy/Tap-to-Pay-on-iPhone--Community-?node-id=0-1&t=E3XskpsLctTuZvg5-1
Questions:
is there any official documentation about the QR code button on this screen?
What happens when user clicks on QR button?
What're the suggestions to show/hide that button, and can we customize it?
Thanks.
Hi everyone,
since updating to Xcode 26 Beta 3, I’m seeing some really strange behavior. I just changed the color of a Color asset in my SwiftUI view – literally just switched from one named color to another – and suddenly:
• Previews stopped working completely, with vague or no error messages.
• Even when I changed the color back to what it was before, the previews still refused to build.
• In addition, Xcode no longer restores the open tabs/windows when reopening the project. It just shows a blank editor every time I open it.
This all happened without touching any project settings or code structure – just a simple color swap.
Has anyone else run into this with Xcode 26 Beta 3?
Would love to know if it’s a known bug or if there’s a workaround (besides nuking Derived Data, which I’ve already tried).
Thanks!
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,
I recently submitted my app to the Apple Store and received a rejection under Guideline 4.3(a) - Design - Spam, stating that my app is similar to others on the store. However, my app has a unique feature set, offers more functionality and content than competitors, and is completely free with ad monetization, unlike most similar apps that require subscriptions.
I have spent five months developing this app from scratch, ensuring it provides an original and valuable experience for users. I did not use an app template or repackaged code, and my app is not a reskinned version of any existing app. I genuinely believe it brings meaningful differentiation to the market.
I would appreciate any guidance on how I can better communicate my app’s uniqueness to the review team or what specific aspects I should adjust to comply with Apple's guidelines.
Thank you for your time and support.
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)
我设计了一个可以键盘输入的蓝牙HID设备,被iphone蓝牙连接后,iphone无法弹出系统键盘,我正试图寻求可以通过修改HID设备代码来解决的方案。
Hello, I am currently trying all of the new features in iOS 26, including some of the new API's. However, there's one question I am not sure of.
In the Build a SwiftUI app with the new design video, there is one section where they show off the Apple Music TabView with one section containing the tabs on the left and the search tab on the right. The scroll down feature I was able to implement. The tabs being split, I have no idea how to do that. How can I do that in SwiftUI?
Hi,
Anybody knows will this occurs when using navigationStack at iOS 18.3? The navigationStack not stay at safeareas
the code as simple as that:
NavigationStack(path: $navManager.path) {
VStack {
Text("Hello")
}
.navigationDestination(for: Route.self) { route in
switch route {
....
}
}
}
.environmentObject(navManager)
.environment(logic)
Can I use the “apple.intelligence” SF symbol to refer to the functionality of Foundation Models frameworks within my app, or does it specifically refer to Apple Intelligence and not a feature of my own creation that is built upon Apple Intelligence?
I've noticed that the App Store app tends to make the selected tab indicator darker on light mode and lighter on dark mode.
Is there any easy way to ensure better legibility out of the box with Tab View (SwiftUI) when using the tint modifier with custom colors?
This has been an issue since installing the first beta and I haven't seen anyone else say anything about it so I feel like I'm going kind of bonkers. While using Dark Mode, double-tapping to select a word while using the Liquid Glass keyboard, like in Messages or Safari, produces a flashlight-like effect over the text with each tap. While this is a fine animation and pretty helpful when moving the cursor, the brightness of the flashlight effect on white text in Dark Mode makes it impossible to see what you're actually tapping to select. The brightness seems to intensify 100x when rapidly tapping. This is not an issue in Light Mode when the text itself is black.
To recreate this, just turn your phone to Dark Mode, go into Messages and type a few words into a thread. Try to double-tap to select a word in the text box. The brightness of the selected word should intensify to the point of being unable to see the word itself.
Has anyone been bothered by this? Is there a way to fix or adjust it? I've tried reducing transparency and a bunch of other settings but nothing has worked.
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.
I have accidentally missed the sign up window for the UX Writing lab by 1 hour, but I'd still love to join it if at all possible. I have had this lab several times in the past and it was always very informative.
I have a time tracking app that helps people make the most of their time. https://apps.apple.com/us/app/timelines-time-tracking/id1112433234
I'm looking for guidance on how to improve copywriting in my onboarding sequence, on my paywall, and overall throughout the app.
Thank you for considering. My Apple ID is lukas[at]glimsoft.com.
App design: macos, Xcode 16.4, Sequioa 15.5, it is sandboxed
Uses: Pods->HotKey for a global hotkey which xcode says "binary compatibility can't be guaranteed"
This app is on the Apple Store and supposedly apps on the Apple Store can't use global hotkeys. Someone internally, installed it from the store and the global hotkey works just fine.
I'm concerned for two potential problems;
I need to find a hotkey library or code that is known to work with a sandbox'd Apple Store app.
Why is it working now when everything I have read says it shouldn't.
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.
Hi,
Normally we need many shades of gray in any App and Apple system have only 3 , Primery, Secondary, and Gray, so to make Gray regress that automatically adapt to Dark Mode we just use opacity on these colors ? there's no system built in Gray degrees ?
Kind Regards
Hello, I am looking to develop a relationship with a developer that has experience running through the IOS build approval process. To elaborate, my team and I have designed and built a software application which is working through the Apple Developer review process to have the app approved and released to the App Store. Unfortunately, there has been some challenges, simple challenges in my eyes with our interface preventing Apple from approving our application. Happy to elaborate further.
A primary problem and solution I have seen is the software build was testing solely on the iPhone but as recently directed it seem the application must be accessible on iPad as well. With this the case, I have experience some software platforms where on the ipad the interface is not displayed on the whole screen. I am looking for direction on how to implement this setup for the 1st IOS build. Another concern from Apples Developer Review team is the App Tracking Transparency kit may need to be implemented.
