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:

I am trying to make an app icon 20 x 20 pixel dimension. I cannot get the icon to be sized this way. It gets blurry. I have used adobe express + illustrator. I have not been able to size it. It is a 400 x 400 dimension png. I want the proportion to be 20 x 20 without losing the clarity.

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?

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. https://youtube.com/CAukICBrVzw 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

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!

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.

When comparing the Assets.car file of the previous and current versions of my app, compiled with Xcode 16 and 26, respectively, with the Terminal command assetutil --info MyApp.app/Contents/Resources/Assets.car I see that the new version contains many more app icons at different sizes, increasing my app's size by 1 MB (not much, but considering that the app is only 6 MB in total...): { "AssetType" : "MultiSized Image", "Name" : "AppIcon", "NameIdentifier" : 6849, "Scale" : 1, "SHA1Digest" : "9D75F76992E9E9E5531A214A4AE282EBD381F7EB903024E00FB25EB42381CC45", "SizeOnDisk" : 308, "Sizes" : [ "16x16 index:1 idiom:universal", "32x32 index:2 idiom:universal", "64x64 index:3 idiom:universal", "128x128 index:4 idiom:universal", "256x256 index:5 idiom:universal", "512x512 index:6 idiom:universal", "1024x1024 index:7 idiom:universal" ] } The previous one allowed me to add only two sizes: { "AssetType" : "MultiSized Image", "Name" : "AppIcon", "NameIdentifier" : 6849, "Scale" : 1, "SHA1Digest" : "AC782A2FFF9A4B2D563EF64DF41A179583440560F8732A176A8376B31000368E", "SizeOnDisk" : 248, "Sizes" : [ "256x256 index:1 idiom:universal", "512x512 index:2 idiom:universal" ] } Is there a way to only ship the strictly necessary app icons sizes while using Xcode 26 Icon Composer, or will all the sizes be required going forward?
