I work for Publix I need that to be trusted in order to download the app what can I do about it

Hi milagros124,

Thanks for contacting Apple Support Communities!

We understand that you'd like to install the Publix app to be trusted on your iPhone.

If your organization uses the Apple Developer Enterprise Program, you can install their app as outlined here: Install custom enterprise apps on iOS - Apple Support

"Your organization can use the Apple Developer Enterprise Program to create and distribute proprietary enterprise iOS apps for internal use. You must establish trust for these apps before you can open them.

If you install an app by Mobile Device Management (MDM), trust is automatically established. If you manually install an app, you must also manually establish trust.

Apple recommends that you use an MDM solution to distribute the apps. This method is secure and doesn’t require user interaction. You can also install custom apps from a secure website that your organization operates. If you don’t install apps from your organization, download and install apps only from the Apple App Store. This is the best way to protect your iPhone, iPad, or iPod touch."

If you need additional assistance, we'd suggest that you reach out to Publix system administrator as they'd be best suited to assist you with their app.

We hope this helps.

Cheers!
