swiftui animation performance swift

I've hit a wall trying to I'm optimizing some code but I'm working on a project and hit a roadblock. I tried several approaches but none seem to work. Working on a project where SwiftUI is the primary framework, I need to create a dynamic interface that includes animated transitions as users interact with a list of items. The challenge arises when I try to animate changes to the list, which occasionally leads to performance hiccups, especially with larger datasets. For instance, I have this basic structure: ```swift struct ItemListView: View { @State private var items: [Item] = [] var body: some View { List { ForEach(items) { item in Text(item.name) .transition(.slide) .animation(.easeInOut) } } .onAppear(perform: loadItems) } func loadItems() { // Simulate loading DispatchQueue.main.asyncAfter(deadline: .now() + 1) { self.items = [Item(name: "Item 1"), Item(name: "Item 2"), Item(name: "Item 3")] } } } ``` Currently, I’m using the `.transition(.slide)` modifier, but when elements are added or removed, the animations are choppy. Looking for the best way to optimize these animations to ensure smoother transitions. I’ve tried adjusting the animation duration and even experimenting with `.animation(nil)` during state changes to see if that helps, but there wasn’t a significant improvement. Also, I read that using `withAnimation` blocks could yield better performance, but I haven’t fully integrated that yet. Should I be leveraging any specific techniques or patterns, like combining animations or managing state in a more efficient way? Any advice on best practices or potential pitfalls to avoid would be greatly appreciated! For context: I'm using Swift on macOS. How would you solve this? My team is using Swift for this mobile app. I'm coming from a different tech stack and learning Swift. This issue appeared after updating to Swift 3.10. I'm open to any suggestions. I'm working with Swift in a Docker container on Windows 10.
