I\'m having some trouble getting my launch image to show up in my application.
I have created all the static image files in the Images.xcassets file in an asset set
Had a similar issue today. Tried to let xCode create automatically the Asset, but it was always unassigned.
The solution was to create manually the Launch Image in the ImageAsset and assign the files for his respective resolution.
It looks like xCode created a different type of Launch Image asset, so it didn't recognized the asset (v8.3.2)
