How do I clear a warning for xcassets unassigned children?

问题

Every time I build I receive two warnings:

<Project name>
    Assets.xcassets
        The launch image set "BrandAsset" has 2 unassigned children.

<Project name>
    Images.xcassets
        The launch image set "BrandAsset" has 2 unassigned children.

Not really sure what to do about this because I am assigning an existing storyboard for the Launch Screen File.

Under Launch Screen Source, I just see a button that says Use Asset Catalog.

How can I fix my build to clear these warnings?

回答1:

just select unassigned items, then, remove: remove unassigned items

回答2:

Assets.xcassets---> "Brand Assets", then right click--->"Remove selected Items"
