Hey guys! I downloaded Apple’s Icon Composer to build my iOS 26 app icon. I exported my SVG from Illustrator (and verified it through Canva and the W3C validator). However, when I import it into Icon Composer, it looks really weird . There are these bubble-like artifacts appearing in the center.
Here's my orignal svg icon file
trace-logo.txt
Any help will be appreciated!
Best, Justin

I have a project, and I prepared an app icon. But I don't know where to drag the .icon, please help me out!
Hi, I just had V1.0 of my app approved on the App Store and I immediately noticed that the icon preview is broken.
It looks good in Xcode, on-device and also in the App Store link preview.
The icon was built with Icon Composer.
Here's the difference (left is App store):
Has anyone encountered the same issue and found a solution?
When creating an icon using icon composer, I cant upload a build to testflight/App Store connect.
Running on device from Xcode works fine, but as soon as I archive and upload to App Store Connect, I get an error saying the icon contains an alpha channel
I'm having a strange issue with my iOS app icon rendering in the App Store - it seems to be low-res and clipping part of the image. I updated the icon in Icon Composer to apply the liquid glass overlay for the new build. It looks fine on the device and the asset itself isn't corrupted. I think it might be a resolution issue since the small icon thumbnails in App Store Connect have the same problem, but they look fine when I click through to the larger preview. Has anyone else run into this and figured out a fix?
How to replicate:
Design a icon in icon composer
Save it and put the .icon file in your project, then in your targets put the name of the .icon file in there. Either clean build folder or restart IDE
One Error:
unable to open dependencies file (/Users/user/Library/Developer/Xcode/DerivedData/project-fqrfzzkwgrutdabmcqjeupvyetci/Build/Intermediates.noindex/project.build/Debug/project.build/assetcatalog_dependencies_thinned)
And one warning:
Icon export exited with status 255, signal 0
Is this a known issue or a easy fix? Or is it a issue on my end? Thanks
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?
I made a new app icon with Icon Composer, and added it to my Xcode project. In the built app, I see AppIcon.icon next to the old AppIcon.icns. But Tahoe is not showing the new icon. Is this because Tahoe has cached the old icon somewhere, and if so, is there some way to make it refresh?
I've been playing around with the recently published iPad PRO M5 13" and it's awesome in most ways I've been able to think of. But this video capture of the app I'm developing, for example, lacks it the app icon "should" be just slightly translucent as I see it.

However I'm not and UI/X person and this is primarily my personal preference only for an option to allow for devs.
Is there a way to display a .icon file in SwiftUI? I want to show the app icon in the app itself but exporting and including the app icon as a PNG feels redundant. This would consume a lot of unnecessary storage especially when including a lot of alternative app icons. There has to be a better way
Otherwise I would file a feedback for that
Thank you
Several app developers are struggling with the inability to provide a separate app icons that looks nice on older macOS versions while at the same time provide Icon Composer icons that look great on macOS Tahoe 26. An ability to provide separate icons is super important to those who have app icons that follow the curvature of the default icon borders (as the corner rounding radius is different for Sequia and Tahoe). Take a look at this for example:
https://github.com/ghostty-org/ghostty/issues/7564#issuecomment-3042061547
Question: Is there a definitive/recommended way to address this issue? How can a developer add a glass icon variant that looks good on Tahoe and provide a bitmap icon for older macOS versions?
Some background info:
Prior to Xcode 26 beta 4, one could add an App Icon to Assets to be used as app icon for legacy macOS versions (Sequia and older) and use a new Icon Composer icon (placed in the project root) for macOS Tahoe 26. Enabling "Include all app icon assets" under target settings ensured that older macOS versions would use the old app icons while Tahoe the new Icon Composer glass one.
Since Xcode beta 4 this technique no longer works. Xcode instead insists on populating Assets.car with Icon Composer generated variants, disregarding the App Icon provided in Assets. Although the App Icon in Assets makes its way to a .incs file in the app bundle's Contents/Resources folder, but that is not used by macOS anymore and is there for some compatibility purposes. The Assets.car file (which matters) only contains the variants generated by Icon Composer and does not contain the png icons provided in the Assets.
I've made my updated icon and I try to import it to Xcode but it keeps crashing even if I clean the project/delete derived data or try to add through the Naivgation Controls.
I've tried with the Xcode 26.2 beta too but it has the same issue.
Hi everyone,
we’re developing an app that lets users export selected bike rides to the HealthKit ecosystem. We created our app icon using the Apple Icon Composer and referenced the composer file in Xcode. Everything works fine, except that the logo doesn’t appear correctly in the Fitness app.
Has anyone experienced this issue or knows how to fix it?

Hi everyone,
I’ve run into a strange issue while building my app with Xcode 26 beta 6 (targeting iOS 26). When I include an app icon created using Icon Composer, the build time jumps to over 5 minutes. During this time, I noticed that a utility called AssetCatalogSimulatorAgent is consuming a significant amount of CPU.
If I remove the Icon Composer-generated icon from my target, the build completes in about 40 seconds. This behavior is consistent across multiple builds.
Has anyone else experienced this? Is there a known workaround or optimization for icons created with Icon Composer? I’d love to keep using the new icon format, but the build time is becoming a real bottleneck.
Thanks in advance!
We have found that on iOS 26 beta some of our app icons built from an Xcode 16 asset catalog containing a single 1024x1024 .png file have a Liquid Glass effect applied to them while others have not.
The documentation states that
If you choose not to use Icon Composer, you can still use an AppIcon asset catalog in your project containing individual app icon images and let the system apply the Liquid Glass material.
and
If you prefer, you can take advantage of the system’s automatically generated treatment that is applied to all app icons.
Is there any insight into how the system treats app icons that have not yet been updated with Icon Composer?

Under my rights as per the Apple Developer Forums Agreement, I am requesting a review per Apple’s right to monitor and correct moderation actions. Thank you.
Currently, the icon composer app can only export the icon with a rounded app background image.
It would be better to support exporting the icon with a transparent background. It can make the exported app icon image with the liquid glass effect for websites, social networks, or other marketing places.
Thank you!
Hi everyone,
I created my app icon using Apple’s Icon Composer tool, a single AppIcon.icon file, set the iOS and Mac Catalyst using shared mode. There’s no AppIcon imageSet in Assets.xcassets.
The app displays the icon correctly at runtime — both on iOS devices and on macOS (Catalyst build). On macOS versions prior to 26, the App Store icon looked completely normal.
However, in App Store Connect and in the Mac App Store on macOS 26, the icon appears with a gray border.
Thanks in advance for any insights or suggestions!
Hi, I'm experiencing a super weird and unexpected issue using Icon Composer (Version 1.0 (40)) and Xcode 26 beta 7.
I have an icon that includes some minimal text in the icon, as part of the branding of the app. The text is an SVG layer in Icon Composer. Icon Composer has no idea this is text, just a regular SVG layer.
When I import the resulting .icon file into Xcode, it appears correct in the Xcode preview.
However, when building the app and installing it on the iOS 26 simulator, the font of the text in the icon changes (to the system default font?). It is also cropped, cut off, and off-center.
I replicated this with a simple standalone icon and clean project.
Is anyone else seeing this?
In the beta of Icon Composer, I see macOS, iOS, and watchOS icons, but there is nothing about visionOS and tvOS. Those icons are particularly hard and it would be great if this app worked for developing icons for all Apple platforms.
I tried asking this in a WWDC group lab, but they didn't get to it and suggested posting to the forum.
