Fail to upload .Net MAUI application on Apple appstore

Question

We have developed an application in .Net MAUI, we tried this application on Android and iPhone device. It works properly on both platform.

Now we are trying to upload this application on Apple AppStore, but fails.

We generate ipa file from Visual Studio and upload it on AppStore using Transporter app on Mac, but fails with following error,

Asset validation failed (90475)

Invalid bundle. Apps that support Multitasking on iPad must provide the app’s launch screen using an Xcode storyboard, or using UILaunchScreen if the app’s MinimumOSVersion is 14 or higher. Verify that the UILaunchStoryboardName key is included in your com.companyname.appname bundle if you’re using a storyboard. For details, see: https://developer.apple.com/documentation/bundleresources/information_property_list/uilaunchstoryboardname (ID: 6b36632c-77f1-4daa-a01a-c22f4089b960)

Asset validation failed (90717)

Invalid large app icon. The large app icon in the asset catalog in “appname.app” can’t be transparent or contain an alpha channel. For details, visit: https://developer.apple.com/design/human-interface-guidelines/app-icons. (ID: 476894b5-d135-41c3-93d2-e05912e43039)

Can you please guide us to resolve this error and upload application on AppStore.

Answer 1

The errors seem pretty clear. To add a splash screen

Answer 2

Hello,

You got three errors, the first is splash screen issue as Bruce said.

The second one is that the format of the large app icon (1024*1024) is not correct, please edit your App icon, see Add an app icon to a .NET MAUI app project - .NET MAUI | Microsoft Learn

The last one said the provisioning profile and the certificate are not matched, refer to
Manual provisioning for .NET MAUI iOS apps - .NET MAUI | Microsoft Learn

Publish a .NET MAUI iOS app for App Store distribution - .NET MAUI | Microsoft Learn

To ensure that you receive a clear and helpful answer to your questions, it's important to post them individually. Please create new thread for the second and the third issues as noted in the Q&A FAQ: How to write a quality question
