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!

So, I started with the developer beta on Tahoe a couple months ago. I gave the new Apps.app a fair shot.... I HATE it. Finally used a terminal work around to get Launchpad back up and running. Now with the release of the Public Beta and Developer Beta 5, Apple has nerfed the Launchpad.app altogether. Apple, listen to your customers. Yes some people really love spotlight but not everyone wants to scroll through a list of apps as long as my leg because, my PTSD brain won't let me remember the name of the app to type into spotlight. The Launchpad app had a great visual reference for those of us with poor memory function. Bring it back, and let your customers choose which one they want to use.
I'm having some trouble getting my widget to display how I want when the user has a tint applied to their home screen. The issue I'm having is with a Text() element, as well as a LinearGradient I am displaying on top of my image. The text should always be white, and the gradient is always black with varying levels of opacity.
I've managed to fix this issue with images displayed in my widget by leveraging
widgetAccentedRenderingMode(.fullColor)
however, there does not seem to be an equivalent of this for non-Image components. I'm aware of
.widgetAccentable(false)
but as I understand it, elements are already considered not accentable by default and you need to explicitly declare widgetAccentable(true) to add them to the accent group. I've tried specifying this to be false up and down my view hierarchy just to see if something will stick but no luck.
Are there any other levers I can pull to preserve the declared colors for my text and gradient components? The images I am displaying is album artwork where preserving the original image is integral, but the tinted text color and overlaid gradient often clash or just looks bad in general. Is there a solution for colored primitive elements?
After updating from iOS 18 to iOS 26, our app icon appears to have automatically received the new 'Liquid Glass' effect. We confirmed that this change occurred without us releasing a new app update.
My questions are:
Is this a system behavior where iOS 26 automatically applies the new icon style to existing apps?
If so, is it possible for a developer to control or customize this effect? I am also wondering if there are any methods other than using Icon Composer.
Hi guys,
Is there any good up-to-date tutorial about publishing a Python based app on Apple Store?
Now, I have developed a standalone Python app from PyCharm, and it's using Pyside6 for UI and some major Python libraries. It's a productivity app with a little A.I. features. I used PyInstaller to prepare the app. Currently, I am stuck at the stage of codesign and Apple Review process, because I am manually doing codesign and building the package from command-line. Without using Xcode, things can get messy or miss easily.
It would be nice to follow a up-to-date tutorial about how to complete the codesign and Apple Review process for a Python based app. For example, what to do, how to do, what to be careful during the Apple Review process, etc. Thanks!
Hi,
This can't be right. Is there really no replacement for Quartz Debug?!?
As the sole developer on a project who has an Intel Mac and Quartz Debug, I am basically a god now.
Everyone else has Apple Silicon and... I think they're randomly guessing at this point.
Because I have entire teams sending me Intel Mac builds of stuff just so I can test it in QD.
This is THE TOOL we used at NewTek to find performance issues, and THE TOOL I used for a dozen companies after that, to help them with similar issues.
If there's no replacement, is there a reason there's no replacement? This feels like a massive step backwards, having to guess at problems like this.

When dismissing a Menu view when the device is set to dark appearance, there is a flash of lightness that is distracting and feels unnatural. This becomes an issue for apps that rely on the user interacting with Menu views often.
When using the overflow menu on a toolbar, the effect of dismissing the menu is a lot more natural and there is less flashing. I expect a similar visual effect when creating Menu views outside of a toolbar.
Has anyone found a way around this somehow?

Just posted this feedback regarding macOS 26 "Tahoe" (FB19853155) - please support with additional submissions if you share my view. I will miss the beautiful and individual designed icons of the past!
"macOS 26 is enforcing squicles for app icons, falling back to a grey background for 3rd party apps without a compliant AppIcon asset.
As a result many original app icons are reduced in size and hard to distinguish because they share the same background color. Although I respect Apple's strive for an iOS-like UI on Macs, a smooth transition path would be more user- and developer-friendly ... e.g. with some info.plist property to opt-out icon migration, potentially ignored by a future macOS version.
The current solution causes a bad usability, and makes the system look inconsistent as many - especially free - software will not be updated with new icon designs. Please reconsider this bad design decision!"
Hello,
I need some help. I’m creating an application, but in fact it is just an instance of a web page built with WordPress and Elementor.
When submitting it for review, the following adjustment is required:

I’m not seeing Liquid Glass on any standard components. A month ago around July 17th I ran our app and saw Liquid Glass on our tab view and various standard components. Those components have not been changed and yet I’m no longer seeing Liquid Glass in our app at all.
Components that were previously liquid glass but now are not include TabView and back navigation buttons.
I set the UIDesignRequiresCompatibility key explicitly to false but no luck. I was seeing this in Beta 7 and Beta 8 on a real device and on a sim.
I'm working on updating our iOS app for the latest Xcode version and noticed the new UIDesignRequiresCompatibility key requirement in Info.plist for apps targeting older iOS designs (without liquid glass). Is there an official timeline for when this compatibility key will be deprecated/removed so that we can plan our liquid glass design changes?
Hi, it seems like using Table on iPadOS 26 results in the table header not applying a background. When comparing the same code on iPadOS 18, the table header applies a blur behind the header to ensure legibility when the user scrolls the content.
Is there a way to ensure Table applies a background effect to the header so that content remains legible during scrolling?
Here is a minimal example:
struct TablePreviewContent: Identifiable {
var id: Int { text.hashValue }
var text: String
}
#Preview {
let content = [TablePreviewContent(text: "Hello"), TablePreviewContent(text: "World")]
Table(content) {
TableColumn("Title", value: \.text)
}
}
I've attached screenshots of the behavior on iPadOS 26 compared to iPadOS 18 to illustrate the issue.
I have two views I've applied Liquid Glass to in Swift UI. I've noticed that depending on the height of the view the material changes and I'm not sure why. See the attached screenshot. Both views add the liquidGlass style in the same way but behave very differently on the same background.
Ideally I'd like them to look the same as the bottom one. Is that the same as the clear style?
With iOS 26 the CPListSection header has a transparent background, and when the list scrolls under the header it doesn't look good at all. We expected to see a glass fading effect maybe, like the one on the top of the screen. Is it a known bug?
I'm using the new badge feature for UIBarButtonItem, but it's not working properly for me when transitioning between view controllers.
I have two view controller with various right bar button items. In the first view controller the first button (the one with the bell) has a badge with a numeric count. The second view controller has the same button but in the third position. When I push the second view controller, it seems that the badge maintains also the old position, so I see two buttons with badges instead of one. What can I do to fix this?
Code that disables a tab bar item via UITabBarItem.isEnabled = false used to both grey out the item and block taps on iOS 18. On iOS 26, the item often remains tappable and selectable, even though isEnabled is set to false. This looks like a behavior change or regression.
func disableTabbarItems(tabbar: UITabBarController, isEnable: Bool, index: Int) {
if let tabItems = tabbar.tabBar.items {
let tabItem = tabItems[index] tabItem.isEnabled = isEnable
}

}

create a sample XCode project using Objective-C and stroybook (xib) using latest XCode beta
open MainMenu.xib, and select Main Menu → File → Print...
remove the image like below
4. build it
5. run it on macOS 26 beta 7
6. The menu item "print.." still have "Image"
Is there any way to remove image for one menu item.
I have also tried NSMenuItem.image = nil, but still not work.
The issue I met on my own app is that I cannot remove icons for "Zoom In", "Zoom Out" and many other menu items, which makes the menu items not aligned properly.
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?
Pinned 2 homes address for the same contact
Steps
Initial check in Apple Maps
No saved places or pinned addresses appear.
Open Personal Contacts
You have two addresses stored in your contact card: Main and Home.
Pin & Edit “Main”
You pinned the Main address in Maps.
Refined the location on the map.
Renamed it (but still saved under the type “My Home”).
Open “Home” Address in Contacts
Refined the location again.
Changed the type to “My Home.”
Attempted to rename, but no option to change the label.
Final Saved Places View
Shows two entries both called “Main.”
Opening either of them displays the same details for the Home address.
Saved Places list only shows the full address text, without the ability to rename them inside Maps.
Results
Both addresses appear duplicated with the same name (“Main”), even though they point to different underlying addresses.
When selecting either entry, Apple Maps incorrectly shows the same Home address details.
The Saved Places section does not allow renaming; it defaults to showing the full address string.
Issues Identified
Sync Conflict Between Contacts & Maps
Apple Maps pulls labels/types from Contacts, but the edits don’t update consistently across apps.
Duplicate Naming Bug
Both “Main” and “Home” collapse into “Main” in Saved Places, making them indistinguishable.
One-to-One Mapping Failure
Regardless of which saved place you open, Maps shows the same Home entry, meaning the system isn’t correctly binding each saved place to its respective contact address.
Renaming Limitation
Apple Maps doesn’t allow renaming saved addresses directly — it relies on Contacts. Since Contacts only supports preset labels (Home, Work, School, etc.), custom naming is blocked.
