Correct Answer:

Explanation:
* RedCircleView()
* GreenTriangleView()
* BlueSquareView()
* BlueSquareView()
* GreenTriangleView()
This question belongs to View Building with SwiftUI , specifically arranging views with HStack , VStack , and ZStack . In SwiftUI, an HStack lays views out horizontally, a VStack lays them out vertically, and a ZStack overlays views front-to-back. Apple's stack layout guidance describes these three containers exactly this way.
To match the canvas, the main HStack must show three items from left to right: a red circle , a green triangle
, and then a right-side vertical group. That means the first two blanks inside HStack are RedCircleView() and GreenTriangleView(). On the right side, the VStack shows a blue square on top, so the next blank is BlueSquareView(). Under that, the lower-right shape is made by layering a green triangle on top of a blue square , which means the ZStack must contain BlueSquareView() first as the background and GreenTriangleView() second as the foreground. SwiftUI's documentation notes that ZStack aligns and overlays its children in depth order, which is why the square goes before the triangle.
So the correct placement order is:
HStack {
RedCircleView()
GreenTriangleView()
VStack {
BlueSquareView()
ZStack {
BlueSquareView()
GreenTriangleView()
}
}
}
That arrangement reproduces the exact layout shown in the canvas.

Explanation:

This question belongs to View Building with SwiftUI , especially the domain covering positioning and/or layout a single SwiftUI View with standard Views and modifiers and the foundational structure of a SwiftUI view. In SwiftUI, a custom screen is typically declared as a struct that conforms to the View protocol. Apple's SwiftUI documentation shows the standard pattern:
struct ScreenView: View {
var body: some View {
Text( " Hello " )
}
}
Here, struct is required because SwiftUI views are commonly defined as structures. View is required after the colon because the type must conform to the View protocol. body is the required computed property that returns the content of the view as some View. Apple documents that every conforming View type must provide a body property that describes its content.
So the completed code is:
import SwiftUI
struct ScreenView: View {
var body: some View {
Text( " Hello " )
}
}
This is the canonical SwiftUI view declaration pattern and is one of the most fundamental concepts in App Development with Swift.

Correct Answer:

Explanation:
* You can treat a NavigationLink like a button, and run some Swift code when it is pressed. - False
* NavigationSplitView can be used to do navigation differently on different device sizes. - True
* You can put a header on your present View in a NavigationStack using .navigationTitle. - True
* If you have a NavigationLink that goes to another View with a NavigationLink, you need to declare a NavigationStack at each level. - False This question belongs to View Building with SwiftUI , specifically the objective on creating a multi-view app with navigation stacks, links, and sheets . Statement 1 is False because NavigationLink is primarily a navigation control that pushes or presents a destination in a navigation container; Apple documents it as creating a navigation link that presents a destination, not as a general-purpose action control like Button.
Statement 2 is True because NavigationSplitView is designed for adaptive navigation and can present navigation in different ways depending on platform and available space. Apple documents NavigationSplitView as a container for navigation across multiple columns, and this adaptive behavior is exactly why it is used differently across device sizes.
Statement 3 is True because .navigationTitle(...) sets the navigation title for a view shown inside a navigation container. Apple explicitly describes a view's navigation title as something used to visually display the current navigation state of an interface.
Statement 4 is False because you do not need a separate NavigationStack at every level. Apple describes NavigationStack as the container that manages a stack of views, and NavigationLink pushes additional destinations onto that stack. Nested destinations can keep navigating within the same stack.
