What’s the first class way to use PhotoKit to reimplement a high performance photo grid? We’ve been using a LazyVGrid and the photos caching manager, but are never able to hit the holy trinity (60hz, efficient memory footprint, minimal flashes of placeholder/empty cells)

A few things. It sounds like you're using the PHCachingImageManager already, which is definitely recommended.

One kind of specific note there—you want to use that to get media content delivered before you need to display it. So, for example, let's say you're showing a large grid of photos. You can be prefetching before and after, in expectation that the user's going to scroll. Or, if you're in a one-up situation, prefetching left and right so that you know the user is likely going to swipe, and you can quickly deliver those images to the screen and cache them.

Another thing you should really make sure you're doing is specifying the size you need for the grid size. For example, if your app supports showing a smaller grid
