Context & Issue
I am developing an iOS application.
My app icon uses colors that are relatively close to each other.
When the user enables Accessibility → Display & Text Size → Color Filters → Grayscale (or similar modes), the icon becomes harder to distinguish because it loses color and contrast is reduced.
Goal
When iOS switches to grayscale mode, I want the app icon to maintain good contrast between its elements so it remains clearly recognizable.
What I’ve tried
Redesigned the icon with more contrasting colors.
Added strokes/outlines, but it still doesn’t look much better in grayscale.
Researched how iOS renders app icons when grayscale is enabled, but couldn’t find a way to override or provide an alternative icon.
Specific questions
Is there any API or mechanism in iOS that allows providing a different version of the app icon when the user has grayscale mode enabled?
If there’s no direct API, are there any best practices for designing iOS app icons to ensure good contrast when converted to grayscale?
Do we have to design grayscale version for app icon?
Thank you!

The built-in screenshot editor in iOS and iPadOS (Markup tool) only allows users to crop images using rectangular frames. While this is sufficient for basic editing, it lacks flexibility for those who wish to tailor the screenshot to the aesthetics of iOS itself — which relies heavily on rounded shapes and smooth UI elements.
⸻
🚫 Current Limitation
• After taking a screenshot and opening it in Markup, users can only crop in rectangular or square formats.
• No option is available to apply rounded corners to the crop.
• As a result, many users are forced to use third-party apps just to achieve a basic rounded-edge crop, which feels unnecessary for such a common need.
⸻
✅ Proposed Solution
Add a rounded corner cropping feature to the screenshot editor.
This could be implemented as:
• A toggle to activate “Rounded Crop”.
• A radius slider (or predefined corner radius presets).
• Optional: an export option to save the result with transparent background, useful for designers and mockups.
⸻
🎯 Why it matters
• Aligns better with the iOS design language (cards, notifications, widgets, etc.).
• Saves time for users who currently have to rely on external editing apps.
• Greatly improves the presentation of screenshots for social media, UI/UX mockups, blogs, and professional use cases.
• Useful across many professions: developers, designers, content creators, educators, marketers.

💡 Bonus Suggestion
Allow exporting with a transparent background when cropping screenshots — especially useful for rounded crops or mockups placed on colored backgrounds.
Hi,
Upon reviewing our app, we got feedback that our app icon within the Wallet app is not behaving as expected when the home screen is set to "light mode" only.
In that case, on the home screen, the app icon remains its default color (e.g., red), regardless of the device's appearance settings (light or dark), which is expected.
However, in the apple Wallet, e.g., under the From Apps from your device, app icons change their color (e.g., red in light mode, black in dark mode) when iOS appearance is changed - which is reported as an app issue.
I've noticed that all apps in that section are changing the color, not just ours, so it seems to me like a bug in iOS or a behavior that was not clearly defined in the app store guidelines.
If there is an API we must use to cover that case, which one would that be?
Is this a bug that Apple should resolve, or is this the intended behaviour?
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?
hi all,
i have dating app, approved in google store, and working website
but i cant get approval from apple review team
( Guideline 4.3(b) - Design - Spam)
can someone help/suggest how to solve it
our app has 2000 clients already
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,
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,
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!
I am creating a shooting game which uses Game Center for multiplayer and I want to make the Matchmaker view look different. How can I do that?
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

Hello All,
I used to own an app named LOLIIPOP, and am in the process of transferring it to my new apple account.
I am having two problems....
How do I transfer the source code and binary to my new apple account?
My developers have an old code, so I need to send them the LAST code they uploaded to the App Store.
How do I do that as well???
Please any help!!!
Thanks,
Mr. LM

We're using StoreKit for in-app purchases on iOS, and our backend has the server notification URL configured. However, during subscription renewals, Apple's server doesn't send any requests to our endpoint. What could be causing this?
Hi all — I wanted to share an idea I recently submitted through Feedback Assistant that I think could improve safety and usability for drivers using CarPlay:
Add an option to overlay live weather radar (rain, snow, storms, etc.) directly onto CarPlay Maps while navigating. Similar to how traffic conditions are shown now, this would allow drivers to visually track incoming weather in real time without switching apps or relying on separate devices.
Why this matters:
• Enhances driver safety by increasing situational awareness
• Helps with trip planning and route adjustments around severe weather
• Reduces distractions by integrating everything into one screen
• Useful for everyday drivers, long-haul travelers, and first responders
I submitted this via Feedback Assistant, but I’d love to know what others think. If you also see value in this feature, consider submitting your own version via Feedback Assistant so Apple sees there’s interest.
Let’s push for smarter, safer navigation — thanks for reading!
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!

Hi everyone 👋
I’ve been using the Apple Pencil Pro with my iPad Pro M4 and absolutely love it — the squeeze gesture, rotation, and haptics are amazing for creative work. But I’ve run into a little roadblock…
Right now, only one Pencil Pro can be paired at a time. So while one is charging, you can’t use another as a backup without unpairing and re-pairing, which interrupts the workflow.
I’d really love to see one of two things:
The ability to use one Pencil while another charges
or
An official external charger (or support for third-party ones)
Personally, I’d happily buy both a second Pencil and a charger if this became possible. I’ve even chatted with other creatives who feel the same — it would make a huge difference for long projects or working on the go.
Just wanted to share this idea and see if anyone else here would like this too. Thanks for reading!
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’m testing our SwiftUI app on both Xcode simulator and a real iPhone. On the simulator, everything looks clean and aligned. But when I run it on an actual iPhone (same build, iOS 18), the layout looks broken—fonts overlap, spacing is off, and elements are misaligned.
Both screenshots are from the exact same screen and time. First is simulator, second is iPhone.
Any idea why this difference happens? Is there something I should check in terms of rendering or layout settings?
Thanks in advance!
I couldn't help noticing that the Maps and Find My apps make extensive use of "sheets stacked on top of each other" to represent its navigation hierarchy, with a "new content comes in from the bottom" orientation instead of a navigation stack with
"new content comes in from the right side" oriented transitions.
I'm interested in this topic because I have a similar navigation-hierarchy-over-a-map case in my app (with a custom map view though) and I'm torn back and forth between the approach of replicating the "stacked sheets" vs. putting a navigation stack in a sheet, esp. with the navstack approach being way more attainable with the iOS 26 glass design.
I couldn't find any guidance for this kind of UI in the Human Interface Guidelines; I'm leaning towards the navstack-approach for my app; but in terms of the behavior of the SwiftUI container views in this scenario it seems a little bit of an uphill path.
Any thoughts on what pattern should be preferred for presenting a deep navigational hierarchy on top of a map-like view?
