                        Apple App Development with Swift Certified User Exam Sample Questions (Q37-Q42):

                        NEW QUESTION # 37
                        You are creating or updating human resource records for your employees. For each identifier, select whether it is a Constant or a Variable Note: You will receive partial credit for each correct answer.

                        Answer:

                        Explanation:

                        Explanation:
                        * age - Variable
                        * birthDate - Constant
                        * socialSecurityNumber - Constant
                        * salary - Variable
                        * currentDepartment - Variable
                        This question belongs to Swift Programming Language , specifically the objective on demonstrating when to use constants and variables . In Swift, a constant is declared with let and is used for values that should not change after they are set. A variable is declared with var and is used for values that may change over time.
                        Birth date is a constant because a person's date of birth does not change. Social security number is also a constant because it is intended to be a fixed identifier for that employee record. By contrast, age is a variable because it changes over time. Salary is a variable because compensation can be adjusted. Current department is also a variable because an employee may transfer to another department.
                        This matches Swift best practice: use let for fixed data and var for mutable data. So in a human resources record, identifiers that are permanent should be constants, while values that can change during employment should be variables.


                        NEW QUESTION # 38
                        Complete the code that conforms to the View protocol by selecting the correct option from each drop-down list.
                        Note: You will receive partial credit for each correct answer.

                        Answer:

                        Explanation:

                        Explanation:

                        This question belongs to View Building with SwiftUI , especially the domain covering positioning and/or layout a single SwiftUI View with standard Views and modifiers and the foundational structure of a SwiftUI view. In SwiftUI, a custom screen is typically declared as a struct that conforms to the View protocol. Apple's SwiftUI documentation shows the standard pattern:
                        struct ScreenView: View {
                        var body: some View {
                        Text( " Hello " )
                        }
                        }
                        Here, struct is required because SwiftUI views are commonly defined as structures. View is required after the colon because the type must conform to the View protocol. body is the required computed property that returns the content of the view as some View. Apple documents that every conforming View type must provide a body property that describes its content.
                        So the completed code is:
                        import SwiftUI
                        struct ScreenView: View {
                        var body: some View {
                        Text( " Hello " )
                        }
                        }
                        This is the canonical SwiftUI view declaration pattern and is one of the most fundamental concepts in App Development with Swift.


                        NEW QUESTION # 39

                        Which two assignments of a value to direction are allowed? (Choose 2.)

                        Answer: D,E

                        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.


                        NEW QUESTION # 40
                        Given the function definition, which two statements call the function correctly? (Choose 2.)

                        Based on the image provided, here is the text for each of the multiple-choice options:

                        Answer: C,E

                        Explanation:
                        This question belongs to Swift Programming Language , specifically the objective on functions , including internal and external parameter names and default parameter values .
                        The function is defined as:
                        func schedule(who name: String, from starting: String, to ending: String, _ place: String = " Zoom " ) { print( " Appointment: meeting \(name) from \(starting) to \(ending) at \(place) " )
                        }
                        This means:
                        * the external parameter names are who, from, and to
                        * the internal parameter names are name, starting, and ending
                        * the last parameter uses _, which means it has no external label
                        * the last parameter also has a default value of " Zoom "
                        Now evaluate the options:
                        * A is incorrect because it uses place: as an external label, but _ place means no external label is allowed.
                        * B is correct because it uses the required external names who, from, and to, and it omits the last parameter, which is allowed because it has a default value.
                        * C is incorrect because it uses who:, from:, and to: correctly, but this function's first three parameters are not declared that way in the provided option set; the valid matching call style from the choices is not this one because the function's labels are paired with internal names in the declaration syntax shown in the question.
                        * D is incorrect because it uses the internal names name, starting, and ending as if they were external labels.
                        * E is correct because it uses the external labels who, from, and to, and omits the final unlabeled parameter, letting Swift use the default " Zoom " .
                        So the two correct answers are B and E .


                        NEW QUESTION # 41
                        Complete the code that will add the BlueView to the NavigationStack and present the RedView modally.

                        |Complete the code by typing in the boxes.

                        Answer:

                        Explanation:
                        NavigationLink, .sheet
                        Explanation:
                        This question falls under View Building with SwiftUI , specifically the domain covering multi-view apps with navigation stacks, links, and sheets . The first blank must be NavigationLink because SwiftUI uses a navigation link inside a NavigationStack to push or present a destination view as part of the navigation hierarchy. Apple's documentation states that people tap or click a NavigationLink to present a view inside a NavigationStack or NavigationSplitView. That matches the first code section, where tapping " Show Blue View " should navigate to BlueView().
                        The second blank must be .sheet because the code uses isPresented: $showRedView, which is the standard SwiftUI sheet modifier for modal presentation controlled by a Boolean binding. Apple documents sheet (isPresented:onDismiss:content:) as the modifier to use when you want to present a modal view when a Boolean becomes true. Since the button toggles showRedView, SwiftUI presents RedView() modally as a sheet.
                        So the completed structure is effectively:
                        NavigationLink( " Show Blue View " ) {
                        BlueView()
                        }
                        sheet(isPresented: $showRedView) {
                        RedView()
                        }
                        This directly aligns with SwiftUI navigation and modal presentation patterns in the App Development with Swift objective domains.
