You have created a view which includes some formatted text:You decide to extract this formatted...

This question belongs to View Building with SwiftUI , specifically the domain on extracting subviews to simplify the structure of an overlarge View .

When you create a custom SwiftUI view and add a stored property like:

let text: String

that property becomes part of the view’s initializer. Since the property name is text, Swift expects you to pass the value using the parameter label text: when creating the view. So the correct call is:

BigGreenTextView(text: " That ' s all folks " )

That makes B the correct answer.

Why the others are wrong:

A is incorrect because this is not using the expected parameter label.

C would only be correct if there were already another variable named text in the calling scope and you wanted to pass that variable instead of the literal string shown in the question.

D is incorrect because it omits the parameter label.

This is a standard SwiftUI pattern: extract reusable formatting into a separate custom View, give it an input property, and then pass the needed value through the initializer using the property label.
