NEW QUESTION # 15
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.)
Answer: B,E
Explanation:
Comprehensive and Detailed Explanation From App Development with Swift domains:
This question falls under Swift Programming Language , specifically the domain for managing data using collection types , with emphasis on dictionaries . In Swift, a dictionary stores data as key-value pairs , so in this example the country name is the key and the capital city is the value. To add a new entry, Swift supports two standard approaches. The first is subscript assignment , which is shown in option C : capitalCities[ " Italy " ] = " Rome " . Apple's documentation explains that you can add a key-value pair to a dictionary by assigning a value for a new key through the dictionary subscript.
The second correct approach is option E : capitalCities.updateValue( " Rome " , forKey: " Italy " ). Apple documents that updateValue(_:forKey:) updates the value for an existing key, or adds a new key-value pair if the key does not already exist . That makes it equally valid for inserting " Italy " : " Rome " into the dictionary.
The incorrect options fail for different reasons. A reverses the key and value, making " Rome " the key and " Italy " the value. B is wrong because append is used with arrays, not dictionaries. D is not the standard valid insertion syntax for Swift dictionaries in this context; Swift's documented mutation approaches here are subscript assignment and updateValue. Therefore, the two correct answers are C and E .
NEW QUESTION # 16
Review the code:
Given a struct called Animal, what line of code should be added on line 5 in order to produce the output shown?
Answer: B
Explanation:
This question belongs to View Building with SwiftUI , especially the objective domain on using List views to iterate through collections and displaying model data in SwiftUI. In the code, animals is the data source passed into List(animals) { animal in ... }. That closure iterates through each element of the collection one at a time, and the parameter animal represents the current Animal instance for that row. To show the name of the current animal in the UI, the correct statement is Text(animal.name). SwiftUI's list documentation explains that each row inside a List must be a SwiftUI View, and a Text view is a standard way to display a string value for each item in the collection.
Option D is therefore correct because it accesses the name property of the current animal object being processed by the List closure. This is the standard SwiftUI pattern when iterating over identifiable model objects: pass the collection into List, receive each item in the closure, and build a row view from that item's properties. Apple's SwiftUI tutorials repeatedly use this collection-driven row-building pattern for lists and navigation.
The other options are incorrect for clear reasons. A incorrectly refers to the type name Animal instead of the current instance. B uses Animals with the wrong identifier and an invalid indexing approach. C also treats animal as an index rather than the current element object. Since the closure already gives you the current Animal, you directly access its property with animal.name.
NEW QUESTION # 17
Review the code snippet.
What value does the code output?
Answer:
Explanation:
Answer the question by typing in the box.
2
Explanation:
This question belongs to Swift Programming Language , specifically the objectives covering functions , control flow , and default parameter values . The function is declared as func getAgeCategory(_ age: Int =
20) - > Int, which means if no argument is supplied, Swift uses the default value 20. Apple's Swift documentation explains that you can define a default value for any parameter, and that value is used when the caller omits that argument. Since the code calls getAgeCategory() with no parameter, the function executes using age = 20.
The conditional logic is then evaluated in order:
* if age > 64 # false, because 20 is not greater than 64
* else if age > 19 # true, because 20 is greater than 19
* so the function returns 2
Because Swift's if / else if control flow stops at the first true condition, the later checks are never reached once age > 19 succeeds. Apple describes Swift as supporting standard control flow including conditional branching, and this example is a direct use of that branching behavior.
Therefore, print(getAgeCategory()) outputs 2 , which corresponds to option B .
NEW QUESTION # 18
What is the code snippet an example of?
Answer: D
Explanation:
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.
NEW QUESTION # 19
Review the code snippet.
What is the value of answer after you run the code?
Answer:
Explanation:
4
Explanation:
This question belongs to Swift Programming Language , specifically the domains covering control flow , loops , and range operators .
The code starts with:
var count = 0
var answer = 0
So both variables begin with the value 0.
In the first loop:
for index in 1...5 {
count = index
}
the closed range 1...5 includes 1, 2, 3, 4, and 5 . During each iteration, count is updated to the current value of index. After the loop finishes, the final value assigned to count is 5 .
Then the second loop runs:
for index in 1.. < count {
answer = index
}
Here, the half-open range 1.. < count means values starting at 1 up to, but not including , count. Since count is 5, this loop runs with index equal to 1, 2, 3, and 4 . Each time through the loop, answer is updated to the current index. After the last iteration, answer becomes 4 .
So the final value of answer is 4 . This question tests understanding of the difference between the closed range operator ... and the half-open range operator .. < , which is a key Swift control-flow concept.
