Apple App Development with Swift Certified User Sample Questions:

Question #1

Which two statements about building an app are true? (Choose 2.)

A. You need a paid Apple Developer account in order to run your app on your phone.
B. You can preview a View in the Canvas without running your app.
C. Your phone must always be physically attached to your Mac to run your apps from Xcode on it.

A. Text(animals[animal].name)
B. Text(Animal.name)

Answer: C

Question #3

For each statement about Navigation in SwiftUI. select True or False.

Answer:

Explanation:
* You can treat a NavigationLink like a button, and run some Swift code when it is pressed. - False
* NavigationSplitView can be used to do navigation differently on different device sizes. - True
* You can put a header on your present View in a NavigationStack using .navigationTitle. - True
* If you have a NavigationLink that goes to another View with a NavigationLink, you need to declare a NavigationStack at each level. - False This question belongs to View Building with SwiftUI , specifically the objective on creating a multi-view app with navigation stacks, links, and sheets . Statement 1 is False because NavigationLink is primarily a navigation control that pushes or presents a destination in a navigation container; Apple documents it as creating a navigation link that presents a destination, not as a general-purpose action control like Button.
Statement 2 is True because NavigationSplitView is designed for adaptive navigation and can present navigation in different ways depending on platform and available space. Apple documents NavigationSplitView as a container for navigation across multiple columns, and this adaptive behavior is exactly why it is used differently across device sizes.
Statement 3 is True because .navigationTitle(...) sets the navigation title for a view shown inside a navigation container. Apple explicitly describes a view's navigation title as something used to visually display the current navigation state of an interface.
Statement 4 is False because you do not need a separate NavigationStack at every level. Apple describes NavigationStack as the container that manages a stack of views, and NavigationLink pushes additional destinations onto that stack. Nested destinations can keep navigating within the same stack.

Question #4

Review the code snippet.

Which statement completes the code snippet so that:
* The lastReleaseDate remains the same when nextApplePhone.releaseDate is nil.

A. lastReleaseDate : nextApplcPhone.rcleaseDate!
B. nextApplePhone.releaseDate : lastReleaseDate
C. nextApplePhone.releaseDate! : lastReleaseDate
D. lastReleaseDate : nextApplePhone.releaseDate
