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.

As the title indicates the problem, the large title is shown but the small title in Navitation Bar view is not shown when scrolled up with iOS26 beta7.
It works with iOS18 or earlier.
Is this iOS26 bug?
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,
App Image: What is the best format - jpg, tiff, giff, psd or ai?
What is the maximum and minimum number of items the app can contain?
Please advise.
Thanks
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.
Building an app to edit the various parameters of digital musical instruments. A typical user would have perhaps max 6 instruments, out of the hundreds of possibilities.
Would like to structure the app with a global window, menu, etc which would be a free download. The user could download editor inserts for their particular set of instruments and ignore all of the others. The downloaded editors would show as options in a menu.
It seem like more than a widget but less than a library. Building a monolithic app containing all possible editors doesn't seem like an option, but separate full-app editors for each piece of gear doesn't sound right either.
Any suggestions out there?
Thanks very much
Brian
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.

I've been beating my head against the wall over a scrollview issue where the top and bottom are cut off in landscape mode. Portrait mode - everything runs swimmingly. The moment I flip the iPad on its side, though, I lose about a quarter of the view on the top and bottom. I thought this was something to do with framing or such; I ran through a myriad of frame, padding, spacer, geometry...I set it static, I set it to dynamically grow, I even created algorithms to try to figure out how to set things to the individual device.
Eventually, I separated the tablet and phone views as was suggested here and on the Apple dev forums. That's when I started playing around with the background image. Right now I have....
ZStack {
Image("background")
.resizable()
.scaledToFill()
.ignoresSafeArea()
ScrollView {
VStack(spacing: 24) {....
The problem is the "scaledToFill". In essence, whenever THAT is in the code, the vertical scrollview goes wonky in landscape mode. It, in essence, thinks that it has much more room at the top and the bottom because the background image has been extended at top and bottom to fill the wider screen of the iPad in landscape orientation.
Is there any way to get around this issue? The desired behavior is pretty straightforward - the background image fills the entire background, no white bars or such, and the view scrolls against it.
i am struggling to get my tab view to work, when i call views in the action part of my tab view, my background creates issue? does anyone know how to fix this?

I have many Apple devices, such as macbook, iPad and iPhone. It's very convenient for me to transfer files between devices. However, when I want to send files to my own device in public places, I often click on the wrong recipient because the list avatar keeps changing. I hope the list of recipients can be grouped One group is my own device (or the one I often send to), and the other group is other devices. When the user is about to send, the mouse will be in a relatively fixed and mentally expected area. I feel that this can reduce the probability of sending wrongly
I have a subscription group with two individual subscriptions configured but when trying to load the SubscriptionStoreView I get the error:
"Subscription Unavailable: The subscription is unavailable in the current storefront."
When I try to load the ProductView, it appears to be stuck in a loading screen. I am running the app on a device that is signed into a sandbox account. Any guidance would be greatly appreciated. Thank you.
Hi all,
I wanted to check whether the NFC bottom-sheet UI shown by iOS during an NFC reading session can be customized.
We have a Figma design (attached) for how the sheet should look, but we are not sure whether iOS allows modifying the default NFC UI.
Is UI customization supported, or is the bottom sheet fully controlled by the system?
Thanks in advance.
Hi,
I want to generate some sample datas for demonstrating the functions of my app when the app launched. My codes are as followings:
func generateSampleData() {
let hasLaunchedKey = "HasLaunchedBefore"
let defaults = UserDefaults.standard
if !defaults.bool(forKey: hasLaunchedKey) {
//generate the demo data
}
defaults.set(true, forKey: hasLaunchedKey)
}
And I put the func in a view's onAppear modifier. I found every time I go the view, it generates the demo data again, which results in producing a lot of demo data. But I have set the status of the function running in the userdefault. Why did it happen?
Best Wishes,

I have been battling the new Icon Composer app for 2 days trying to build an app icon. However, I cannot get it to import any files. I have used the Apple provided App Icon Template. I have exported my layers to .svg and when I open the finder, everything is disabled. I can't find help for this anywhere. I am on Sequoia on my Mac and not sure how to design this app icon without access to the composer.
Hi Apple developer community. I have a question a lot of users don’t like the new control center and notification center. Are you guys gonna blur the background or are you guys gonna keep it the same?
