Apple App Development with Swift Certified User Sample Questions:
Select the location to set this app to run on an iPhone 14 in the simulator.
Correct Answer:
Explanation:
This question belongs to Xcode Developer Tools , specifically the domain for building and running an app on the iOS simulator . In Xcode, the place where you choose whether the app runs on a simulator or a connected device is the run destination / scheme destination selector in the toolbar. This control appears near the top center of the Xcode window and displays the current destination, such as a simulator model or device target. To run the app on iPhone 14 , you click that selector and choose iPhone 14 from the available simulator list. Apple's Xcode documentation describes choosing a run destination before building and running the app in Simulator or on a device.
So, for the hotspot, the correct place is the device/simulator dropdown in the top toolbar , not the preview canvas controls, not the project navigator, and not the code editor. That selector determines where the app launches when you press Run.
Given the function, which two function calls are valid? (Choose 2.)
- A. let sun = rightSum(numl: 100, num2: 50)
- B. let sum r\ ght5um(100, by: 50)
- C. let sum - rightSum(100, by: 30, and: 20)
- D. let Sun - rightSum(numl: 100, by: SO, and: SO)
- E. let sum = rightSum(100, num2: SO, and: 20)

Complete the code that conforms to the View protocol by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct answer.
Correct Answer:
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.
In SwiftUI, how can you extract a subview from a main view to make the code more modular?
- A. Add the subview's code directly into the main view's body.
- B. Use @State to manage subview content and use a binding to create a two-way connection.
- C. Create a new SwiftUI view struct and call it in the main view.
- D. Declare the subview as a variable inside the main view and call it directly.

Drag the views on the left to the correct locations m the code on the fight to match the shown canvas.
You may use each View once, more than once, or not at all.
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.
