Hello, I want to extract values from text field into my class.

class keyWord: ObservableObject {

   @Published var term: String = ""
   @Published var description: String = ""

}

struct ContentView: View {

    @ObservedObject var keyword:keyWord = keyWord()

    var body: some View {

        NavigationView {

            TextEditor("Enter the term", text: $keyword.term)

            TextEditor("Enter Description", text: $keyword.description)

        }
    }
}

The :keyWord part is fine, for the same reason that :String is fine in the keyWord class. Neither are nnecessary in this example but fine if they are there.

The problem is that TextEditor only takes one parameter.

So this:

TextEditor("Enter the term", text: $keyword.term)

TextEditor("Enter Description", text: $keyword.description)

should be:

TextEditor(text: $keyword.term)

TextEditor(text: $keyword.description)

And definitely use @StateObject here instead of @ObservableObject.

Also, this isn't a problem per se, but you really should name your types with capital letters. So KeyWord instead of keyWord. The convention in Swift is to start type names with capital letters and variables with lowercase letters. It helps make your code more readable and understandable.

FYI, it helps when asking for help if you explain what problem you are seeing. Do you get an error that prevents compilation? A crash? etc. Just saying "what's my mistake" doesn't really help anyone figure things out. In this case, it was pretty simple, but it might not always be.
