Apple-Hosted Background Assets question

I have a Vision Pro app, which I intend to use Apple-Hosted Background Assets for some of my videos after watching:

https://developer.apple.com/videos/play/wwdc2025/325

I added a Apple-Hosted, Managed extension.

New Target -> Background Download -> Apple-Hosted, Managed

After creating an Archive, I tried uploading it to TestFlight, it complains about a DTPlatformName error in my Info.plist. So I added the following :

<key>DTPlatformName</key>
<string>xros</string>

With which, I managed to upload the app with the extension to TestFlight. However, when I tried installing the app on TestFlight to Vision Pro, it gives me an error that says the app cannot be verified.

Any help or pointers is greatly appreciated.

Info.plist

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>EXAppExtensionAttributes</key> <dict> <key>EXExtensionPointIdentifier</key> <string>com.apple.background-asset-downloader-extension</string> </dict> </dict>

</plist>

Entitlements

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.application-groups</key> <array> <string>group.net.connectcode.spatialcatvideos</string> </array> </dict> </plist>

I have previously upload an aar asset with Transporter.

The error message after adding the DTPlatform based on the error message "ITMS-90508: Invalid Info.plist value - The value for the key 'DTPlatformName' in bundle Spatial Cat Videos.app/Extensions/HostedCatVideos.appex is invalid."
