Obfuscation doesn't work on ionic angular mobile iOS app

I am using

"webpack-obfuscator": "^3.5.1"

My goal is to obfuscate my 'ionic build' output folder called www. This www folder is archived in the .ipa the iPhone executable. The source code in that www folder which mainly consists of html, css and js files. This is readable and its readability can be avoided using obfuscation.

I have made changes in my angular.json file as follows to be able to inject web Obfuscator plugin as shown as below:

"architect": {
"build": {
"builder": "@angular-builders/custom-webpack:browser",
"options": {
"customWebpackConfig": {
"path": "./extra-webpack.config.js",
"mergeStrategies": {
"externals": "replace",
"module.rules": "append",
"plugins": "append"
}
},

"serve": {
"builder": "@angular-builders/custom-webpack:dev-server",
"options": {
"browserTarget": "app:build",
"customWebpackConfig": {
"path": "./extra-webpack.config.js",
"mergeStrategies": {
"externals": "replace",
"module.rules": "append",
"plugins": "append"
}
}
},

Nothing fancy, angular.json file finds a custom web pack json and reads the plugin from there resulting in code obfuscation. Please refer extra-webpack.config.js contents below:

var WebpackObfuscator = require('webpack-obfuscator');
const path = require('path');

module.exports = {
resolve: {},
plugins: [
new WebpackObfuscator({
rotateStringArray: true
}, ['polyfills.js'])
],
module: {
rules: [
{
test: /\.js$/,
exclude: [
path.resolve(__dirname, 'excluded_file_name.js')
],
enforce: 'post',
use: {
loader: WebpackObfuscator.loader,
options: {
rotateStringArray: true
}
}
}
]
}
}

Code obfuscation is done, the output www folder code is not readable but the app throws console errors while running which is shown as below:

Even If we ignore these console logs in the iOS app while running the app, the navigation stack is completely broken. The app doesn't not navigate to new screen.

Any help is appreciated. I am out of ideas here.

Thanks in advance

Comienza con angular.json y extra-webpack.config.js, luego vuelve a ejecutar ionic build e inspecciona los archivos generados www/main.js, vendor.js y polyfills.js junto con el stack trace de iOS informado. Comprueba qué configuración de ofuscación causa los errores en tiempo de ejecución y la navegación rota; se considera terminado cuando la aplicación iOS ofuscada se ejecuta y navega sin esos errores.
