SwiftUI iOS AsyncImage Swift

I'm deploying to production and After trying multiple solutions online, I still can't figure this out. I'm refactoring my project and I'm sure I'm missing something obvious here, but I'm facing an issue with a custom image carousel built using SwiftUI. On my iPhone 14 Pro running iOS 17.1, the images are rendering incorrectly; sometimes they appear blank or have strange artifacts. I’ve implemented a simple carousel using a `TabView`, but it seems to only display the first image correctly, and others come in with a delay or not at all. Here’s a snippet of my code: ```swift import SwiftUI struct ImageCarousel: View { let images: [String] @State private var currentIndex = 0 var body: some View { TabView(selection: $currentIndex) { ForEach(0..<images.count, id: \ .self) { index in AsyncImage(url: URL(string: images[index])) { image in image.resizable() .aspectRatio(contentMode: .fill) .frame(height: 250) .clipped() } placeholder: { ProgressView() } } } .tabViewStyle(PageTabViewStyle()) .onAppear { autoScroll() } } private func autoScroll() { Timer.scheduledTimer(withTimeInterval: 3.0, repeats: true) { _ in withAnimation { currentIndex = (currentIndex + 1) % images.count } } } } ``` I've tested the URL images in Safari, and they load fine, so I don't believe it's an issue with the image sources. I also tried using `Image` instead of `AsyncImage` to see if that would help, but the rendering issues persist. The images occasionally flicker as well, especially when scrolling. Has anyone else encountered a similar issue? What could be causing these rendering artifacts, and how can I fix them? I’ve already made sure to clear the cache and even restarted the device, but that didn’t help. What's the best practice here? I've been using Swift for about a year now. Is this even possible? I'm working with Swift in a Docker container on CentOS. Thanks in advance! This is for a REST API running on Ubuntu 20.04. Cheers for any assistance!
