                        NEW QUESTION # 10
                        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: A,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 # 11
                        Which two statements about building an app are true? (Choose 2.)

                        Answer: D,E


                        NEW QUESTION # 12
                        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: A,C


                        NEW QUESTION # 13
                        Select the area in Xcode that allows you to display the Preview Canvas.

                        Answer:

                        Explanation:

                        Explanation:
                        This question belongs to Xcode Developer Tools , specifically the objective domain on identifying and using the features of the Xcode interface . In the screenshot, the correct area is the upper-right corner of the editor toolbar , where Xcode provides the control for editor display options. Apple's documentation explains that to show previews, you can use the editor controls and specifically notes that you can click the Adjust Editor Options button and choose Preview , which displays the preview canvas to the right of the editor.
                        So, in hotspot terms, the correct selection is the editor options control near the top-right of the code editor
                        , not the Run button, not the Inspector, and not the Project navigator. This aligns with Apple's preview workflow for SwiftUI in Xcode, where the canvas is shown from the editor display controls. Apple also describes the preview canvas as part of Xcode's interface for quickly visualizing UI changes while editing code.


                        NEW QUESTION # 14
                        Review the code snippet and then predict the output.

                        Answer: C

                        Explanation:
                        This question belongs to Swift Programming Language , especially the domains covering control flow , loops , logical operators , and guard . The loop runs through 0.. < max, and since max = 101, the values of num are 0 through 100. Inside the loop, the guard statement keeps only values that satisfy both conditions:
                        * num % 5 == 0 # the number must be divisible by 5
                        * num % 2 != 0 # the number must be odd
                        So the code counts numbers from 0 to 100 that are odd multiples of 5 . Those values are:
                        5, 15, 25, 35, 45, 55, 65, 75, 85, 95
                        That gives a total of 10 numbers. Therefore count becomes 10, and the printed output is:
                        Total count: 10
                        The key Swift concept here is that guard ... else { continue } skips any loop iteration that does not meet the required condition. Only matching values reach count += 1. This is a standard use of guard for early exit and of the remainder operator % for divisibility checks. Therefore, the correct answer is B .
