Apple App Development with Swift Certified User Exam App-Development-with-Swift-Certified-User Prüfungsfragen mit Lösungen (Q11-Q16):

11. Frage
Review the code.

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

Antwort:

Begründung:
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.


12. Frage
What is the code snippet an example of?

Antwort: B

Begründung:
This question belongs to Swift Programming Language , specifically the objective domain on Optional types and safe unwrapping . The snippet uses if let favoriteCol = favoriteColor { ... }, which is Swift's standard syntax for optional binding . Apple's documentation explains that optional binding is used to conditionally bind the wrapped value of an optional to a new constant or variable if the optional contains a value. That is exactly what this code does: if favoriteColor is not nil, its unwrapped String value is assigned to favoriteCol, and the code inside the if block runs.
This is not force unwrapping , because force unwrapping uses the ! operator, such as favoriteColor!. It is not optional chaining , because optional chaining uses ? to safely access properties, methods, or subscripts on an optional value. It is also not an implicitly unwrapped optional , which would be declared with String! rather than String?.
So the correct answer is C. Optional binding . This pattern is one of the most important safe-handling techniques in Swift because it lets you work with optional values only when they actually contain data, avoiding runtime errors and keeping control flow explicit.


13. Frage
Review the code.
var capitalCities = [ " USA " : " Washington D.C. " , " Spain " : " Madrid " , " Peru " : " Lima " ] Which two statements add the capital city of " Italy " to the dictionary? (Choose 2.)

Antwort: C,E


14. Frage
Select the area in Xcode that allows you to display the Preview Canvas.

Antwort:

Begründung:

Explanation:
This question belongs to Xcode Developer Tools , specifically the objective domain on identifying and using the features of the Xcode interface . In the screenshot, the correct area is the upper-right corner of the editor toolbar , where Xcode provides the control for editor display options. Apple's documentation explains that to show previews, you can use the editor controls and specifically notes that you can click the Adjust Editor Options button and choose Preview , which displays the preview canvas to the right of the editor.
So, in hotspot terms, the correct selection is the editor options control near the top-right of the code editor
, not the Run button, not the Inspector, and not the Project navigator. This aligns with Apple's preview workflow for SwiftUI in Xcode, where the canvas is shown from the editor display controls. Apple also describes the preview canvas as part of Xcode's interface for quickly visualizing UI changes while editing code.


15. Frage
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.

Antwort:

Begründung:

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.
