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.

Correct 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.

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.
