질문 # 11
Select the location to set this app to run on an iPhone 14 in the simulator.
정답：
설명：
Explanation:
This question belongs to Xcode Developer Tools , specifically the domain for building and running an app on the iOS simulator . In Xcode, the place where you choose whether the app runs on a simulator or a connected device is the run destination / scheme destination selector in the toolbar. This control appears near the top center of the Xcode window and displays the current destination, such as a simulator model or device target. To run the app on iPhone 14 , you click that selector and choose iPhone 14 from the available simulator list. Apple's Xcode documentation describes choosing a run destination before building and running the app in Simulator or on a device.
So, for the hotspot, the correct place is the device/simulator dropdown in the top toolbar , not the preview canvas controls, not the project navigator, and not the code editor. That selector determines where the app launches when you press Run.
질문 # 12
Review the code snippet.
Which statement completes the code snippet so that:
* The lastReleaseDate remains the same when nextApplePhone.releaseDate is nil.
* The lastReleaseDate updates to the nextApplePhone.releaseDate when nextApplePhone.releaseDate is NOT nil.
정답：B
설명：
This question is from Swift Programming Language , especially the domains for Optional types , safe and unsafe unwrapping , and control flow . The code uses the ternary conditional operator :
nextApplePhone.releaseDate != nil ? _____
In Swift, the ternary operator follows this structure:
condition ? valueIfTrue : valueIfFalse
So if nextApplePhone.releaseDate != nil is true, the expression must return the new release date. If it is false, it must keep lastReleaseDate unchanged. That means the missing part must be:
nextApplePhone.releaseDate! : lastReleaseDate
which is option D .
This works because nextApplePhone.releaseDate is declared as String?, so it is an optional. Once the condition confirms it is not nil, the code force-unwraps it with ! to access the underlying String value. If the optional is nil, the expression returns lastReleaseDate instead. Apple's Swift documentation describes the ternary conditional operator as a shortcut for choosing one of two expressions based on a condition, and it explains that force unwrapping with ! accesses an optional's wrapped value when you know it is not nil.
The other options are incorrect because they reverse the true/false logic, omit the needed unwrap, or contain invalid identifiers. Therefore, the correct completion is D .
질문 # 13
What is the code snippet an example of?
정답：C
설명：
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.
질문 # 14
When you press ' Show Button ' on your app. a modal View appears.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct answer.
정답：
설명：
Explanation:
This question belongs to View Building with SwiftUI , specifically the domain on creating a multi-view app with navigation stacks, links, and sheets .
To present a modal view in SwiftUI when a Boolean state changes, the correct modifier is .sheet . The matching sheet API for a Boolean binding is:
sheet(isPresented: $showInfo) {
// modal content
}
So the first blank must be .sheet , and the second blank must be (isPresented: .
The logic works like this:
* @State stores the local Boolean that controls presentation.
* Pressing the button calls showInfo.toggle(), changing the value from false to true.
* When that Boolean becomes true, the .sheet(isPresented:) modifier presents the modal view.
* When the modal is dismissed, SwiftUI updates the Boolean back as needed.
There is also a typing issue in the screenshot: the state variable appears as ShowInfo, while the button and binding use showInfo. Swift is case-sensitive, so those names must match. The corrected code should use the same identifier consistently, such as:
@State var showInfo = false
Therefore, the correct dropdown selections are:
sheet
(isPresented:
질문 # 15
In SwiftUI, how can you extract a subview from a main view to make the code more modular?
정답：A
설명：
Comprehensive and Detailed Explanation From App Development with Swift domains:
This question belongs to View Building with SwiftUI , specifically the objective about extracting subviews to simplify the structure of an overlarge view . The correct answer is C because the standard SwiftUI approach to modularizing a large interface is to create a separate custom view, usually as a new struct conforming to View, and then use that view inside the main view. Apple's tutorials and documentation repeatedly show this pattern: move part of the UI into its own SwiftUI view type, then compose the main screen from smaller view components.
Option A is not the primary SwiftUI pattern for extracting a reusable subview. Option B does the opposite of modularization, because it keeps everything in the same large body. Option D is about state management and data flow, not about extracting a visual component into its own reusable subview. Apple's SwiftUI materials emphasize composition, where views are lightweight and can be split into smaller reusable pieces for clarity, maintainability, and reuse. WWDC guidance also shows Xcode's "Extract Subview" workflow, which creates a separate view structure from selected UI code.
