If you are completely new to coding, maybe consider working through Swift Playgrounds. It's an educational iPad by Apple for teaching kids to code. Might look like a toy at first, but it's a solid step-by-step, hands-on way to learn coding without the overwhelming experience of a professional grade coding environments like XCode, or the intense learning curve of getting started with React Native. It uses Swift, so it could be a good starting point for building apps. If you already have coding experience, this may be too top-level for you.
