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 looking for guidance on how people have solved this problem/use case. What is the best way to structure a seat based subscription app that an organization can pay for seats for all their users, can be distributed via mdm or via app store and is easy (low friction) to get paid for and started for small companies? I market to a business to buy my app, they want it installed on all 25 devices they have. They use ABM to acquire 25 licenses with and MDM to distribute. The app is currently free to download so ABM charges $0 but has a paywall to use. The paywall is a RevenueCat one and no user account is needed. All entitlements and free trial work great. When it is deployed to the 25 devices, they can either sign up with their own AppleId and own/company credit card, or use a company appleid and company card for all 25 devices to solve the issue but neither are great. Doubtful they would want to pay their money for a company required app on a company phone (don’t blame them). If they share an appleid, my MRR drops to 1/25th since they will just share the purchase. Any suggestions would be greatly appreciated.

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!

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()

Hey there! I'd love to know if theres a way where you can animate items between ZStack and VStacks? Just like the native iOS notifications on the Lockscreen stack at the bottom and if tapped, they convert from a Stack to a List - I have a list with items, displayed in a VStack, and I make the list collapsable when swiping down, where the items stack behind eachother with a progresisve reduction in opacity & scale, but I havent figured out a way to animate the items between the list and the stack - where you can visually see items starting to overlap and stack ontop of eachother when collapsing the list.

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.

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.

Does iOS 26 support HDR images for app icons to be rendered in High Dynamic Range for Springboard or not?

I'm trying out Icon Composer Version 1.0 (27.4). I imported a simple logo and sized it in the outer circle. The icon appears good in the Icon Composer. But when I export the file and use it for my app icon it seems to be missing a margin or padding that other native application icons have. Am i supposed to be adding my own padding to these resulting icons or am I building them incorrectly? Any guidance would be appreciated. Thanks!

Hello, I used icon composer to create an icon for my Mac OS app and it seemed to have worked. I see the app icon everywhere except for window expose or stage manager. Any help or guidance would be greatly appreciated!

I can't find any documentation on design guidelines for "Login with Game Center" button. My app allows users to "Play as Guest" or "Login with Game Center". Since Apple provides somewhat strict guidelines for designing "Sign in with Apple" button, i was wondering how to design the button for Game Center login. Should i use Game Center icon. And will Apple review reject this?

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.

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?

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 Guy Desbief

I would really like to be able to categorize my contacts. I work for a grocery store and have contacts from various companies. I would like to be able to categorize them by company or group them as I see fit. Currently, I don't see a way to do this. Please add this in a future update. Having all contacts just alphabetically is not efficient enough. Also, I would like to be able to manually adjust the size of widgets. i.e. If I want more stocks to be visible, I would like to be able to lengthen the height/width of the widget beyond what it currently allows to view more information. Thank you. If you have any follow-up questions, please let me know. Torrey

Hi, is it me or latest beta has pronlem with brightness? i have iPhone 16 pro, and now i must keep disabled auto brightness , at keep slider more or less at maximum, in order to clearly see the screen. fabrizio

Hi everyone, I've noticed that on iOS 26 beta 1 through beta 4, when using a List with the .plain style, the section header overlaps with the cell content below it, as there is no background for the header. This creates a poor visual experience. Additionally, when using NavigationSplitView on iPad, the second column's list always shows this issue. Is this an intentional design change, or just a temporary issue? I haven't found a good workaround so far. Thanks! FB19066489
