I know the basics of swift.I understand concepts and programs very well when I'm practicing them on the playground in the Xcode. But when I begin building the apps by watching the tutorials, I don't really understand how the things work. Im trying very hard but not in the right way.Ive taken all the basic lessons which taught me the fundamental concepts like variables, arrays, functions,classes,operators etc. What are the other basic things I need to lea in order to lea app building? Thank you in advance!
