So I want to start to learn how to code Apps for iPhone. I have basic knowledge of HTML, CSS, C++ and C#. I have not decided yet which program to use: Xcode or Visual Studio Code (I already used second one for other projects). Now...I had this idea of an app with functions like Google Lens - image recognition. I thought maybe I need some kind of database with example pictures? But how do I code that? And how do I program the app to access the camera? Thanks for help.
