How do I use the Launch Images from an Asset Catalogue in the Launch Storyboard?
I know this is an old question. Short answer is "you can't", but there is a workaround.
Here is how I do it:
Do not add the images you want to use to an asset catalog. Instead, add the images directly to your project and make sure you have them included in the target. You have to go back to the old "image.png", "[email protected]", "[email protected]" naming convention in order to supply different images for different screen sizes.
Hope that helps anyone who comes across this.
