Apple App Development with Swift Certified User Sample Questions:

Question #1

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. Create a new SwiftUI view struct and call it in the main view.
  • C. Declare the subview as a variable inside the main view and call it directly.
  • D. Use @State to manage subview content and use a binding to create a two-way connection.
Answer: B

Question #2

Refer to this image to complete the code.

Note: You will receive partial credit for each correct answer

Answer:


Explanation:

This question belongs to View Building with SwiftUI , especially the objectives for using List views to iterate through collections and structuring views with standard SwiftUI containers. The screenshot shows two grouped sets of rows: one headed MY FRIENDS and one headed MY PETS . In SwiftUI, the correct container for a scrollable table-style presentation of rows is List, and the correct way to divide that list into labeled groups is Section. Apple documents List as a container that presents data in a single-column row- based layout, and Section as a way to organize list content into grouped areas with headers and optional footers. That is exactly the structure shown in the image. ( developer.apple.com , developer.apple.com ) The ForEach(names, id: \.self) and ForEach(pets, id: \.self) lines are already iterating through the arrays, so each ForEach should be wrapped inside a Section. The section labels such as " My Friends " and " My Pets
" are provided with the header: label. So the intended code structure is:
List {
Section {
ForEach(names, id: \.self) { name in Text(name) }
} header: {
Text( " My Friends " )
}
Section {
ForEach(pets, id: \.self) { pet in Text(pet) }
} header: {
Text( " My Pets " )
}
}
This matches the UI shown in the image and aligns directly with SwiftUI list and section composition patterns in App Development with Swift.

Question #3

You are creating or updating human resource records for your employees. For each identifier, select whether it is a Constant or a Variable Note: You will receive partial credit for each correct answer.

Answer:


Explanation:
* age - Variable
* birthDate - Constant
* socialSecurityNumber - Constant
* salary - Variable
* currentDepartment - Variable
This question belongs to Swift Programming Language , specifically the objective on demonstrating when to use constants and variables . In Swift, a constant is declared with let and is used for values that should not change after they are set. A variable is declared with var and is used for values that may change over time.
Birth date is a constant because a person's date of birth does not change. Social security number is also a constant because it is intended to be a fixed identifier for that employee record. By contrast, age is a variable because it changes over time. Salary is a variable because compensation can be adjusted. Current department is also a variable because an employee may transfer to another department.
This matches Swift best practice: use let for fixed data and var for mutable data. So in a human resources record, identifiers that are permanent should be constants, while values that can change during employment should be variables.

Question #4

Which property wrapper allows you to read data from the system or device settings?

  • A. @StateObject
  • B. @Binding
  • C. @State
  • D. @Environment
Answer: D

Question #5

Given the function definition, which two statements call the function correctly? (Choose 2.)

Based on the image provided, here is the text for each of the multiple-choice options:

  • A. E. schedule(who: " Jane Doe " , from: " 9:30am " , to: " 10:30am " )
  • B. schedule(who: " Jane Doe " , from: " 9:30am " , to: " 10:30am " , place: " Office " )
  • C. D. schedule(name: " Jane Doe " , starting: " 9:30am " , ending: " 10:30am " , place: " Office " )
  • D. schedule(who: " Jane Doe " , from: " 9:30am " , to: " 10:30am " , " Office " )
  • E. schedule(who name: " Jane Doe " , from starting: " 9:30am " , to ending: " 10:30am " )
