After updating xcode all images in the storyboard appeared as question marks (as it doesn\'t find them). I tried to remove/add them, cleared derived data but still all image
You have to use xcassets catalog for your images:
1) Access Assets.xcassets
2) Create new Image Set or choose from the list and update existing one
3) Place your image variants in its @1x, @2x and @3x sizes:
Call your image in your code like:
let image = UIImage(named: "NewImageName")
