Problems With Developing An App

Hi Chris. I checked out your YouTube channel on IOS App Development Tutorial. After going through the videos and tried to practice it, but I still struggle to make an app. On top of that, Xcode new updates makes it more difficult for me to even create and test applications. I can’t find the button. I really want to develop an app and put in the App Store. The types of apps I want to develop are subscription apps. I want to succeed in the app development space. I was wondering if you help me out on how I can do that? How can I learn IOS App Development better and improve better so that I can create any apps that I want? Looking forward to hearing from you.
