NEW QUESTION # 37
Review the code snippet.
The " faces " dictionary contains emojis and their descriptions.
Which code will create an array named " emo)is " that will copy all the emojis from the " faces " dictionary?
Answer: B
Explanation:
This question belongs to Swift Programming Language , specifically the objective on managing data using collection types , including dictionaries and arrays . In the dictionary shown, the emojis are the keys and the text descriptions are the values . Swift provides a keys property on dictionaries that returns a collection containing all dictionary keys. To convert that keys collection into an array, you use the Array(...) initializer.
Therefore, the correct code is let emojis = Array(faces.keys). Apple documents both the Dictionary.keys property and the Array type used to store a sequence of values of the same type.
Option B is incorrect because faces.values would return the descriptions like " grinning " , " thinking " , and " happy " , not the emoji keys. Options A and C are incorrect because List is a SwiftUI view type, not the correct collection type for creating an array from dictionary contents. Also, the dictionary interface uses properties like .keys and .values, not method calls like .keys() or .values(). Apple's dictionary documentation makes clear that keys is a property returning a collection of the dictionary's keys.
NEW QUESTION # 38
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: C
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.

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: C,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 # 40
Which two statements about building an app are true? (Choose 2.)
Answer: C,E
Explanation:
Comprehensive and Detailed Explanation From App Development with Swift domains:
This question belongs to Xcode Developer Tools , especially the objectives about using the Xcode interface, building and running an app, and debugging. A is true because Xcode supports SwiftUI previews in the canvas, allowing you to see a view's interface directly in Xcode without fully launching the entire app in the normal run workflow. Apple's documentation states that Xcode can display a preview of a custom SwiftUI view in the preview canvas and keep it updated as you make code changes.
D is also true because when you run an app from Xcode on a device, Xcode opens a debugging session in the debug area. Apple explicitly documents that after a successful build, Xcode runs the app and opens a debugging session, which means you can view debug information while the app is running on the phone.
The other options are false. B is false because a phone does not have to be physically attached at all times; modern Xcode workflows support device pairing and wireless development after setup. C is false because Generic iOS Device is not an actual simulator run target for launching the app like a specific simulator device. E is false because you do not need a paid Apple Developer Program membership merely to run an app on your own device for development; Apple provides support for development testing on devices with the required setup such as pairing and Developer Mode.
NEW QUESTION # 41 
Which two assignments of a value to direction are allowed? (Choose 2.)
Answer: C,D
Explanation:
This question belongs to Swift Programming Language , specifically the domain covering basic Swift types and how Swift handles enumerations . The code defines an enum named CompassPoint with the cases north, south, east, and west, and then declares direction as type CompassPoint. In Swift, an enum case can be assigned using the fully qualified form CompassPoint.north, so B is valid. Swift also allows the shorthand form .north when the compiler already knows the expected type is CompassPoint, so D is also valid. Apple's Swift language documentation explains that once a variable is known to be of a specific enumeration type, you can set its value using the shorter dot syntax.
The other options are not allowed. A is invalid because enum cases are not assigned using constructor-style syntax like CompassPoint(north). C is invalid because north by itself is not enough unless it is written with dot shorthand in a context with inferred enum type. E is invalid because north is a case of the enum type, not a member accessed from the variable instance as direction.north. Swift enum cases are referenced from the enum type or by shorthand dot syntax, not as instance properties.
