I am trying to upload my Maui app to app store connect. Consistently running into "Asset Validation Failed" for icon sizes 120x120, 167x167, 152x152, 1024x1024.
However, every once in a while it will go through totally fine, I didnt do anything different in those cases.
So far I have ensured the appicon is set to MAUI icon. That it is a multiple of 8. I have tried cleaning and rebuilding, deleting bin and obj folders all in different sequences. I have also tried switching back to the sample .NET maui appicon with no luck.
I can also confirm that the contents.json file is referencing the appicons correctly and all the appicons that are "missing" are present inside the release xcassets folder. I reference this xcassets folder in the info.plist.
I was able to publish the sample maui app with no issues. I have tried cross referencing this sample project with mine (namely the csproj file & info.plist) and I do not really see any difference.
I have opened up the ipa file and "decrypted" the assets.car file. I notice that when my app uploads successfully the appicons are referenced in this file and when it doesnt work they do not. But I do not understand what causes this difference.
Has anyone run into a similar issue. Or has anyone been able to modify an ipa after creation and resign and reseal it and publish to appstore?

How did you set the icons? You could refer to Change the app icon - .NET MAUI | Microsoft Learn
And I'm not sure how you publish the app, please see Publish a .NET MAUI iOS app for App Store distribution - .NET MAUI | Microsoft Learn
In addition, may I ask the detailed VS version, Xcode version and MAUI version? Could you share the detailed error message("Asset Validation Failed" for icon sizes 120x120, 167x167, 152x152, 1024x1024.)?
Hi Wenyan,
Thanks for taking the time to help out!
I set icon like in the url you mentioned.
I also followed the link you mentioned to publish the app. I have tried pushing it onto the appstore using transporter, visual studio & xcode.
I am using visual studio for mac 17.5.6 (build 3), I have also tried visual studio for mac preview 17.6 preview. (17.6 build 1539).
I am using xcode Version 14.3.1 (14E300c).
I am using .NET 7
maui-ios 7.0.86/7.0.100 SDK 7.0.300
I can also provide build and archive logs if that is helpful.
Thanks!
There are several things need to confirm with you.
<MauiIcon> items defined in the project file(.csproj file).XSAppIconAssets in Info.plist , and the value should be Assets.xcassets/XXX(your icon name).appiconsetIn addition, the image with error message is hard to work with, please edit the error message as text into the post.
Turns out I had two appicon references. That seems to have resolved 2 of the 4 errors (thanks :)). My updated error log is below.
Asset validation failed (90022) Missing required icon file. The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format for iOS versions >= 10.0. To support older versions of iOS, the icon may be required in the bundle outside of an asset catalog. Make sure the Info.plist file includes appropriate entries referencing the file. See https://developer.apple.com/documentation/bundleresources/information_property_list/user_interface (ID: 93dd37f6-92f2-4cbb-8bc7-a431bcb04d50) Asset validation failed (90704) Missing App Icon. An app icon measuring 1024 by 1024 pixels in PNG format must be included in the Asset Catalog of apps built for iOS, iPadOS, or watchOS. Without this icon, apps cannot be submitted for review.

I tried replacing my svg with others (didnt seem to help unfortunetely). I am able to "validate" my app now I get these errors when I try to deliver it. I also confirmed that I have the correctly appicon reference in my info.plist.
I will try rolling back my xcode to 14.3.
When you "validate" the app, there is no error, right? Do you validate your app via Xcode? Can you export and save an .ipa file then upload it to the App Store through Apple's Transporter? And you said you could publish the sample MAUI app with no issues, so, would you mind sharing your icon svg file with me so that I can test? In addition, would you mind sharing the .cproj file with me?
(I test with an empty MAUI template project via VS17.6 preview, Xcode14.3.1, it works. I can publish the ipa to AppStore Connect by Apple's Transporter )
Yeah that is the process I was following, unfortunately no luck. Can I send the files to you via email?
No. It's not allowed to provide email account on Q&A. You could try to open a support ticket for this and contact our paid phone support at MS. You will get 1:1 support on that.
What ended up solving the issue was targeting a physical ipad when archiving instead of the generic device.
Thanks for your sharing.

Is there any other solution for this, I need to archive and upload without the need of the physical device, Basically achieving this with fastlane for CI/CD

Honestly I think the tooling is just somewhat buggy. I still run into this issue every now and again. Usually if I increment the bundle version in the info.plist it does the trick. But lately that isn't working either.
