It's a custom app I've created.

Here are more explanations regarding my contraints: For security reasons I don't want to manage the app's secrets under GIT My app's secrets can't be managed by certificates I don't want to build a new app each time secrets change I want to manage theses secrets through files To manage all these contraints, I think the best way is to deploy my custom app in two steps: deploy custom app on device deploy files on device into custom app Library folder That's why I'm looking for something to install remotely files into app data container (Library folder) once the app is already on device.

We'll use Apple Business Manager to deploy this app.

Thanks for your answers. I better understand the operation. But it's a lot of dev and permissions to request to just get the SSID of the current wifi...

Here is the log from a test device: error_ca_cert.txt Can you tell me what's wrong during the trust evaluation ? Regards.
