Hello! I am developing an ebook reader iOS app that uses c/c++ codec as a page renderer.
The codec uses TrueType as a font rendering engine that requires access to .ttf (or .ttc) files.
Currently, I supply TrueType with fonts embedded in the app package, so they lay within the app sandbox.
The codec supports the whole unicode plane and many languages that ebooks may use, but the fonts I supply don't have some of the important glyphs (i.e. katakana or hangul).
I see that iOS has its own font storage, located in /System/Library/Fonts/ directory. The codec is able to parse this directory and read .ttf files located inside, using these fonts as a fallback in the case when the supplied fonts can't draw certain glyphs.
I use opendir and fopen(in "rb" mode) as a way to read the data, and it works well.
Does this type of access to the system directory violate the sandbox rule for an app distribution, and, if yes, is there a way to get access to stored .ttf files not violating the mentioned rule?

We are working on one of the projects for Hackathon for which we need to access the 3D Models of Apple Watch, it will help in making our project more realistic and effective, I wanted to know if we can get access for the same.
With the new ios 26 beta 3 helps some stabillty and performance issues but most of the liquid glass has been removed or made very frosty look; and it defeats the whole purpose of a big redesign, and even thought the changes are because of readability and contrast complaints it should not take away liquid glass design. I think apple should consider adding a toggle or choice to choose if they would want a more frosted look or a more liquid glass look the the original plan.
I placed apple.logo symbol image on the top of a view. This view is used to link or unlink Apple ID for user. In the middle is the apple sign in button. I want to use something to describe or represent what the view is, instead of using text description. so I think sign in's company logo is a good choice. Is it allowed by apple official?
I noticed a discrepancy between the Material specifications for tvOS on the Developer page and the naming in the Design Resources (Sketch files). Which one should we consider authoritative?

I like this font. but in license only allowed for use in Mockup UI.
Feel free to use in commercial?

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.
Scenario is when keyboard is opened within the app being developed then switch to other app, for instance, Notes app and create a note to enable keyboard from there. While the Notes app keyboard is active switch back to the developed app the keyboard in it is dismissed. Any thoughts?Thanks
Where is the Figma App Icon Template mentioned in the Developer session https://developer.apple.com/videos/play/wwdc2025/361?
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?

On iOS 26 beta 3, my app and some other apps got greyed out app icon.
It only happens in Default (Light) appearance.
Apple automatically converts third-party app icons to support Liquid Glass, but is there any specific requirement with third-party icons to avoid above greyed out app icon issue?
Dear Developer, Is there a way to create a function to search with inside a text without having to be outside all of the messages? In other words, could I go into one of my contact’s texts and then search specifically inside that message as can be done on Android? This would be such an amazing function And make life so much easier. Thank you.
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,
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!
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!

I found that on my cutomer's mac device, webflterproxyd start interferiing with the NE traffic. Tried to stop it, but "screen time" was not enabled at all.
Who started this webfilterproxyd process and how to stop it?
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
Hi everyone 👋 I’m a new iOS developer working on my first app and I’ve run into a frustrating visual bug involving my app icon during the launch/close transition.
Issue:
When I use Icon Composer (the new tool introduced for iOS 26) to generate my app icon, I consistently see a thin white border or “fringe” around the icon only during the transition animation (when the app opens or closes). It disappears once the animation ends.
What I tested and confirmed:
• I exported the exact same design directly from Adobe Illustrator as a 1024×1024 PNG, fully opaque, RGB color mode, background color filling the entire canvas (no transparency, no borders, no rounded corners).
• When I place that exported PNG directly into the AppIcon asset catalog in Xcode, the icon renders perfectly — no white fringe appears, just a slightly darker shade of blue during transitions (expected and acceptable).
• But when I generate the icon using Icon Composer, the white edge always appears, even if I disable effects, use full coverage layers, or only keep a flat color layer.
Notes:
• Tested on iOS 26 (latest beta) using Xcode 16.
• The issue seems specific to Icon Composer’s export format or metadata — maybe it’s not stripping alpha correctly or something related to the squircle mask?
• I followed all recommended specs: 1024×1024 px, PNG, sRGB, no transparency, exported from Illustrator at 72ppi with solid background.
Even tested without the logo, just the icon made with icon composer
Is anyone else experiencing this issue with Icon Composer exports?
Is there an official recommendation to avoid this during transitions or should I simply avoid Icon Composer for production icons for now and stick with Illustrator / Figma exports?
Thanks so much
Here’s a visual example:
Hello Apple Developer Support,
We initially uploaded our INRx App on a different Apple Developer account for internal testing purposes.
Now, we would like to publish the same app under a new Apple Developer account for production, but we're currently facing a design-related rejection during the review process.
We believe the app meets all guidelines, and there were no design issues flagged previously when submitted from the testing account.
Could you please help us understand:
Why the same app is now being rejected for design issues?
Is there a way to resolve this while moving the app to the new account?
Any advice or clarification would be greatly appreciated so we can successfully proceed with publishing.
Thank you!
Forgot to turn off the ui element status bar. visual garbage.
is it not important? your opinion
