NEW QUESTION # 21
Why does the initializer for the following struct need the keyword self?
Answer: B
Explanation:
This question belongs to Swift Programming Language , specifically the objective covering structs, properties, and initializers .
In the struct, both the property and the initializer parameter are named age:
struct person {
var age: Int
init(age: Int) {
self.age = age
}
}
Here, age inside the initializer could refer to either the property of the struct or the parameter passed into the initializer. Swift uses self.age to clearly mean the property that belongs to the current instance , while plain age refers to the initializer parameter . So self.age = age means: assign the parameter value to the instance property.
That is why C is correct. The keyword self is required here to remove ambiguity between two identifiers with the same name.
The other options are incorrect:
* A is wrong because self here is not pointing to the parameter; it points to the instance property.
* B is wrong because self is not always required in every initializer assignment. It is specifically needed here because of the naming conflict.
* D is wrong because whether the property has a default value is not the reason self is needed in this example.
So the correct answer is C. self is needed to distinguish between the property and the parameter with the same name.
NEW QUESTION # 22
Complete the code that will add the BlueView to the NavigationStack and present the RedView modally.
|Complete the code by typing in the boxes.
Answer:
Explanation:
NavigationLink, .sheet
Explanation:
This question falls under View Building with SwiftUI , specifically the domain covering multi-view apps with navigation stacks, links, and sheets . The first blank must be NavigationLink because SwiftUI uses a navigation link inside a NavigationStack to push or present a destination view as part of the navigation hierarchy. Apple's documentation states that people tap or click a NavigationLink to present a view inside a NavigationStack or NavigationSplitView. That matches the first code section, where tapping " Show Blue View " should navigate to BlueView().
The second blank must be .sheet because the code uses isPresented: $showRedView, which is the standard SwiftUI sheet modifier for modal presentation controlled by a Boolean binding. Apple documents sheet (isPresented:onDismiss:content:) as the modifier to use when you want to present a modal view when a Boolean becomes true. Since the button toggles showRedView, SwiftUI presents RedView() modally as a sheet.
So the completed structure is effectively:
NavigationLink( " Show Blue View " ) {
BlueView()
}
sheet(isPresented: $showRedView) {
RedView()
}
This directly aligns with SwiftUI navigation and modal presentation patterns in the App Development with Swift objective domains.
NEW QUESTION # 23
If View A calls View B, which Swift Property Wrapper would you use in View B in order to return the value of a state to View A?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From App Development with Swift domains:
This question belongs to View Building with SwiftUI , specifically the objective on using @State,
@Binding, @Environment, and observable data to share data between views.
The correct answer is @Binding because @Binding creates a two-way connection to a value that is owned by another view. In this scenario, View A owns the state, and View B needs to read and modify that value so the change is reflected back in View A. Apple's SwiftUI documentation describes a binding as a reference to a mutable value that is owned elsewhere, which is exactly the pattern used when a child view needs to update a parent view's state. ( developer.apple.com )
@State is not correct for View B here because @State is used for local state owned by that specific view. If View B used @State, it would manage its own separate copy rather than updating the parent's value.
@Environment is used to access values provided by the system or ancestor views, not for directly returning a specific parent state value in this pattern. @Observable is related to observable model objects and is not the direct property wrapper used in a child view for two-way parent-child state passing. ( developer.apple.com ) So when View A passes a state value into View B and expects updates to flow back, View B should use
@Binding .
NEW QUESTION # 24
Review the code snippet.
The code snippet does not compile.
Which two actions will fix the errors? (Choose 2.)
Answer: B,E
Explanation:
This question belongs to Swift Programming Language , especially the domains covering basic Swift types
, operators , and constants versus variables .
There are two compile problems in the snippet. First, unitPrice and shipping are inferred as Double, while quantity is inferred as Int. In Swift, arithmetic operands must have compatible types; Swift does not automatically mix Int and Double in one arithmetic expression. So unitPrice * quantity fails unless quantity is changed to Double or explicitly converted. That makes A a correct fix.
Second, the line totalCost += ... uses the compound assignment operator +=, which stores a new value back into the left-hand side. Swift requires the left-hand side of += to be mutable, so totalCost must be declared with var, not let. That makes D the second correct fix.
The other choices do not solve the actual compile issues. B is unnecessary because totalCost is already explicitly declared as Double, so 0 is valid there. C would still leave shipping as Double, so the mixed-type arithmetic problem remains. E is irrelevant because shipping is never reassigned. Therefore, the two correct answers are A and D
NEW QUESTION # 25
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.
Answer:
Explanation:
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.
