Image loading optimization in React Native app using FastImage - advanced patterns on iOS

react-native fast-image ios JavaScript

I'm following best practices but I'm working on a personal project and I'm migrating some code and I'm integrating two systems and I'm having trouble with I'm working on a project and hit a roadblock..... I'm working with an scenario with loading images in my React Native app using the `react-native-fast-image` library. The images load fine on Android, but on iOS, they sometimes don't appear at all, especially when I try to load remote images that are supposed to be cached. I have set the `resizeMode` to 'cover' and specified width and height correctly, but the images still unexpected result to render after the initial load. Here’s a snippet of my code: ```javascript import FastImage from 'react-native-fast-image'; const MyImageComponent = () => { return ( <FastImage style={{ width: 200, height: 200 }} source={{ uri: 'https://example.com/my-image.jpg', priority: FastImage.priority.normal }} resizeMode={FastImage.resizeMode.cover} /> ); }; ``` I tried adding behavior handling to see if there are any issues with the image source, but I don't see any console errors. Instead, I just get blank spaces where the images should be. ```javascript <FastImage style={{ width: 200, height: 200 }} source={{ uri: 'https://example.com/my-image.jpg' }} onError={(behavior) => console.log('Image load behavior: ', behavior)} /> ``` Despite this, I still don’t see any output in the console. I also tried clearing the cache and reinstalling the app, but that didn't help. I checked the network tab in the debugger and confirmed that the images are being requested, but the response is sometimes a 404 for certain images. I’m using `react-native-fast-image` version 8.3.1 and React Native version 0.67.0. Is there a specific configuration or a workaround for this scenario on iOS? Any help would be greatly appreciated! Thanks in advance! I'm working with Javascript in a Docker container on Ubuntu 22.04. I'd really appreciate any guidance on this. I'm developing on Debian with Javascript. I recently upgraded to Javascript 3.9. I appreciate any insights!
