質問 # 27
Review the code.
When entered into the TextField, which number will display a blue canvas on the SecondView?
正解：D
解説：
This question belongs to View Building with SwiftUI , especially the domain on creating multiple views to implement app logic and sharing values between views. In FirstView, the value typed into the TextField is stored in number, which is a String. When the NavigationLink is tapped, the code passes Int(number) ?? 0 into SecondView. In Swift, converting a string to an integer with Int(...) uses an optional initializer, which means it returns an optional value and will produce nil if the string cannot be converted. The ?? 0 nil- coalescing operator then supplies 0 if conversion fails.
Inside SecondView, the body is:
Color(passedNumber == 3 ? .blue : .red)
This uses the ternary conditional operator. If passedNumber equals 3, the displayed color is blue; otherwise, it is red. Therefore, entering 3 into the TextField causes Int(number) to become 3, which makes the condition passedNumber == 3 true and displays a blue canvas. Any other listed number results in red.
So the correct answer is A. 3 . This matches the SwiftUI pattern of taking user input, converting it to the needed type, passing it into another view, and rendering UI conditionally based on that value.

Review the code.
Note: You might need to scroll to see the entire block of code.
A breakpoint is set on line 3. When the application is run. it will stop at line 3. You need to debug the code.
Drag each debugging control from the left to the correct instruction on the right. You will receive partial credit for each correct answer
正解：
解説：
Explanation:
This question belongs to Xcode Developer Tools , especially the objective on using debugging techniques including breakpoints and stepping controls .
When execution stops at a breakpoint on line 3, Step Over runs that line without entering into another function call, so it is the correct action for moving past line 3 while staying in the current function. Step Into is used when execution reaches line 4 and you want to enter the display(numbers) function, which takes you into the function body starting at line 8. Once inside that function, Step Out continues execution until the current function returns, which is exactly what "step out from line 8" means.
Deactivate breakpoints turns breakpoint handling off so the debugger no longer stops on active breakpoints.
Continue program execution resumes the app until the next breakpoint or until the program finishes.
So the correct control order is:
1 = Continue
2 = Deactivate breakpoints
3 = Step Over
4 = Step Into
5 = Step Out
質問 # 29
Review the code snippet and identify what happens when the program is executed.
正解：C
解説：
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 .
質問 # 30
In SwiftUI, how can you extract a subview from a main view to make the code more modular?
正解：A
解説：
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.
