Visuals not displaying in the official app release

Currently, I am facing an issue with loading local images in my react-native application. Interestingly, the images load perfectly fine when the server is running in development mode, but they do not appear when using the release version. Strangely, the app itself functions without any problems.

The method I am using to load the images is as follows:

// components/Test.js
export default function Test() {
    return (
        <Image source={ require('../assets/icons/food/cupcake.png') } />      
    );
}

I am wondering if I am making a mistake somewhere in this process. Do I need to make changes in xcode or adjust some settings? Additionally, during dev mode, I have observed that the images seem to be requested from the dev/hot loading server every time there is a render, rather than being bundled along with the JavaScript code.

My current setup includes:
- react-native version 0.34
- xcode Version 8.0 (8A218a)

Answer №1

After troubleshooting, I was able to find a solution which resolved the issue at hand:

When creating a bundle, be sure to include the command --assets-dest ./

"react-native bundle --platform ios --assets-dest ./ --dev false --entry-file index.ios.js --bundle-output iOS/main.jsbundle"

This will generate both the main.jsbundle file and an Assets folder. In Xcode, simply right click to add the main.jsbundle file to your project, then drag and drop the Assets folder while selecting 'create by reference' (do not choose 'create group').

It's also important to note that the main.jsbundle may sometimes reference assets in an 'Assets' folder with a capital 'A', causing issues. By renaming this folder to 'assets' and importing it into Xcode, the problem was resolved.

I hope this explanation helps solve any similar problems you encounter!

Answer №2

While I may not have extensive knowledge in react native, from my experience, xcode typically mandates configuring "copy bundle resources" within the build phases of your target settings.
