Apple App Development with Swift Certified User Exam Sample Questions (Q22-Q27):

NEW QUESTION # 22
You have a set of Views within a ZStack that produce the screen below:

Arrange the lines of code that will make up the ZSlack so that the View appears as shown.

Answer:

Explanation:

This question belongs to View Building with SwiftUI , specifically stacking views and applying modifiers. A ZStack layers views from back to front, so the first item becomes the background and later items appear on top. To match the screenshot, the black background must be the back layer, so Color.black goes first. The large white circle sits above that, so Circle() followed by .foregroundStyle(.white) comes next. Finally, the red heart image sits on top of the circle, so Image(systemName: " heart " ).resizable() followed by .
foregroundStyle(.red).frame(width: 200, height: 200) must be last. SwiftUI's Image.resizable() allows the symbol image to scale to the frame you apply, and foregroundStyle sets the visible color styling for the shape and symbol.
So the intended structure is:
ZStack {
Color.black
Circle()
.foregroundStyle(.white)
Image(systemName: " heart " ).resizable()
.foregroundStyle(.red)
.frame(width: 200, height: 200)
}
This produces a black background, a white circular shape, and a centered red heart on top, exactly as shown.

NEW QUESTION # 23
Review the code snippet.

What will print after the final line of code is executed?

Answer:

Explanation:
Answer the question by typing in the box.
2
Explanation:
This question belongs to Swift Programming Language , specifically the objective on variable scope and shadowing .
The code first declares:
let even = 2
This creates a constant named even in the outer scope with the value 2.
Inside the for loop, the code declares another constant with the same name:
let even = num * 2
This inner even exists only inside the loop body. It shadows the outer even, which means that within the loop, the name even refers to the loop's local constant, not the original one. However, that inner constant goes out of scope at the end of each loop iteration.
After the loop finishes, the inner even no longer exists. So when the final line runs:
print(even)
Swift uses the original outer constant, which is still 2.
So the output is:
2
This question tests two important Swift concepts:
* Scope : where a variable or constant can be accessed
* Shadowing : when a local declaration temporarily hides another declaration with the same name Therefore, the correct answer is 2 .

NEW QUESTION # 24
You have created a view which includes some formatted text:

You decide to extract this formatted text into a subview so that you can reuse the formatting for other texts.
You highlight the Text and choose Extract subview.
You refactor ExtractedView to BigGreenTextView.
You add the line let text: String to the extracted view above the body.
You replace " That ' s all folks " with a reference to text
How should you call this extracted View from the original View?

A. BigGreenTextView(text: text)
B. BigGreenTextView(text: " That ' s all folks " )
C. BigGreenTextView( " That ' s all folks " )
D. BigGreenTextView(text)

Answer: B

Explanation:
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.

NEW QUESTION # 25
Review the code snippet and identify what happens when the program is executed.

A. The for loop prints all the menu items in the array.
B. Only menu items including " Pizza " . " Burger " , " Chicken " . " Pasta " . " Salad " are printed.
C. Only menu items including " Burger " . " Chicken " . " Pasta " . " Salad " are printed.
D. Only menu items including " Burger " . " Chicken " . " Pasta " . " SaJad " . " Steak " are printed.

Answer: C

Explanation:
This question belongs to Swift Programming Language , specifically the objectives covering arrays , loops
, and range operators . The array has 6 elements, so menuItems.count is 6. The loop uses the half-open range operator:
for index in 1.. < (menuItems.count - 1)
That becomes:
for index in 1.. < 5
In Swift, the half-open range operator a.. < b includes the lower bound but does not include the upper bound.
So this loop runs with index values 1, 2, 3, 4, not 0 and not 5.
Array subscripting uses those indexes to print:
* menuItems[1] # " Burger "
* menuItems[2] # " Chicken "
* menuItems[3] # " Pasta "
* menuItems[4] # " Salad "
That means " Pizza " at index 0 is skipped, and " Steak " at index 5 is also skipped. Swift arrays use zero- based indexing, and count returns the number of elements in the array.
Therefore, the program prints only " Burger " , " Chicken " , " Pasta " , and " Salad " , so the correct answer is A .

NEW QUESTION # 26
Review the code.

You need to add the word " Great! " to the Capsule shape.
Complete the code by typing in the boxes.

Answer:

Explanation:
overlay, Text
Explanation:
This question belongs to View Building with SwiftUI , particularly the domain involving positioning and/or laying out a single SwiftUI view with standard views and modifiers . To place text on top of a shape such as a Capsule, SwiftUI uses the overlay modifier. Apple documents overlay as a view modifier that layers one view in front of another, which is exactly what is needed here: the text should appear on top of the blue capsule rather than beside or below it. The second blank must therefore be Text , because SwiftUI uses a Text view to display string content like " Great! " .
The completed code is:
struct ContentView: View {
var body: some View {
Capsule()
.fill(.blue)
.frame(width: 200.0, height: 100.0)
.overlay(
Text( " Great! " )
.font(.largeTitle)
)
}
}
This works because Capsule() creates the shape, .fill(.blue) gives it the blue color, .frame(width:height:) sets its size, and .overlay(...) places the Text( " Great! " ) directly above that shape. This is a standard SwiftUI composition pattern: build a base view, then apply modifiers to style it and layer additional content. In App Development with Swift objectives, this aligns with understanding standard views, modifiers, and layout techniques in SwiftUI.
