Text And Button with SwuiftUI

Upon creating a new project, we see a dialog to select the project name:

After creating the project, we see the file list on the left sidebar, the code and preview in the center, and the properties of the selected object on the right.

In SwiftUI, the main term we encounter frequently is “View.” This is a protocol, and to display an object, we need to use this protocol. By default, it provides methods to manage the properties of objects. Another interesting keyword is “some,” which refers to an “opaque type.”

I found a helpful post explaining this concept: https://medium.com/@PhiJay/whats-this-some-in-swiftui-34e2c126d4c4 . I recommend giving it a read. If you’d prefer a summary, the key point is:

“Adding this keyword turns the return type into an opaque type, meaning 
that both you and the compiler know this function will always return 
only one specific concrete type — but you’ll never know exactly which one!”
