Hi, I am a novice Swift developer, wanting to develop an app or three for my own use for now and as a learning experience. I want use Swift/SwiftUI to download a file (.sqlite) from AWS S3 Bucket and then upload when complete. I am trying to follow Amazon's tutorials but finding it difficult to apply to my code. So far I have been able to import the necessary packages (I think) into Xcode, but that is far as I have progressed.
Are there any good examples or templated that I can use to get started?
Also another newbie question, what make ContentView.swift the first/parent view of the application?
I Appreciate your patience and assistance.
