iOS build not functioning due to dotenv function

line 9 in index.tsx is causing the following error when building on an iOS device:

**iOS Bundling failed
The package at "node_modules\dotenv\lib\main.js" attempted to import the Node standard library module "path".
It failed because the native React runtime does not include the Node standard library.

Removing this line fixes this error and allows me to view the pages, however I don't know if this will cause anything in the backend to fail. We need to check that this change won't cause any issues and, if so, proceed with removing the line.
