Assets catalog .webp warrning

When I enter webp image to the assets catalog I get warrning: /Users/..../Assets.xcassets The image set "Card-Back" references a file "Card-Back.webp", but that file does not have a valid extension. It works, I see all my images perfect. How can I fix the 200+ warrnings?

The size of the asset has increased more than three time in the assets.car file after signing the ios app

The assets in the Asset.xcasset lesser than the asset in the Assets.car file. Because of this the iPA file size increased three times as Assets.car file inside the iPA increased. Why do the asset file size increased enormously. How do we prevent this ? I used Version 26.2 (17C52).

.icon files and "imageNamed:"

Composer icons can be loaded with NSImage's imageNamed: but I haven't figured out how to make it load any variation other than the light style. Is this even possible? Thank you!
