SwiftUI/Firebase assistance

I require minor things done.
1. I have a button set up where I want the user to fill a form and add an image that should all be uploaded to firebase. When that particular record is selected the associated image should become viewable. The data does upload to firebase but I need the image to do the same and be retrievable.
2. Face ID / Touch ID has been set up and a toggle button included, I’d like that when the user sets the toggle switch to “off” the app doesn’t request Face ID when logging back in but will instead head straight to the main view.
