Hi! I getting a lot of errors in ForEach and I don't know why at all.

Here is the code: In line 19

"Generic struct 'ForEach' requires that 'Artwork' conform to 'RandomAccessCollection'"

Thanks! Any help would be deeply appreciated!

your view model is publishing an array (a random access collection of artworks), but your ArtworkGridView declares a single var artwork: Artwork . You're asking ForEach to iterate over something that isn't a collection.
