hi, in the settings in the application settings, how do I put a button there to allow the use of the camera?

Hello everyone, I'm programming my app and after a few days I opened and ran it on my iPhone. This app worked, but with one big problem. The problem is that the app doesn't show up in my settings and I don't know why. I didn't program/change anything. Thanks for the advice

Hello everyone, my app i'm developing doesn't show up in phone settings. By default, I install the application on the phone, then it starts, but I don't see it in the phone settings. I need it in the settings to enable the use of the camera, but I won't confirm it at the moment. Thanks everyone for your help

Hello everyone, I don't know what to do with my problem. I have a barcode reader in my application which is solved via VisionKit. There are other pages in the bottom bar and they are resolved by TabView. The problem is that when I switch screens, my camera freezes. Does anyone know how to solve this? Thanks for the reply

Hello everyone, first let me say a few words about myself. I am an IT student and I want to learn and develop some applications in Swift. Now I am working on one application and I need a barcode scanner to complete it. So I need help from someone who can help me with a simple barcode scanner. My idea is that the barcode will be on one screen and they have to read the code and write it to a variable. That's my idea. I will appreciate the full code or help. thank you for answer
