Same for me. Any idea or feedback number?

It's a free app, so anyone can download it, for free. "Family Sharing" is for sharing the subscription. My app doesn't have any Family sharing options enabled on any offered in-app subscriptions. You may be true if Family sharing was enabled. That's not the case.

Same here. When opening my project with a widget on Xcode 15 and building it to launch on my iPhone on iOS 15, it works. Same project and target device using Xcode 16 RC, I got the error listed above and widget is not showing in the widget list.

Same for me. Any idea?

Same issue with Xcode 16.2 beta 16B5100e. It's still a problem for us because we need iOS 15 support for our widget.

Same for me. I got the message after upgrading Xcode version to 16.3.

I found a workaround; not documented for the moment. You can use this build setting configuration for asset catalog: ASSETCATALOG_OTHER_FLAGS = "--enable-icon-stack-fallback-generation=disabled"; Make sure you also checked Include all app icon assets option if you want a different icon for iOS 18 and lower and have a combination of AppIcon in an asset catalog and an .icon file.
