Apple App Development with Swift Certified User Exam 認定 App-Development-with-Swift-Certified-User 試験問題 (Q21-Q26):

質問 # 21
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.

正解：

解説：

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.


質問 # 22
Review the code snippet and then predict the output.

正解：A

解説：
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 .


質問 # 23
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.)

正解：C、E


質問 # 24
Which two statements about building an app are true? (Choose 2.)

正解：B、C


質問 # 25
Why does the initializer for the following struct need the keyword self?

正解：D

解説：
This question belongs to Swift Programming Language , specifically the objective covering structs, properties, and initializers .
In the struct, both the property and the initializer parameter are named age:
struct person {
var age: Int
init(age: Int) {
self.age = age
}
}
Here, age inside the initializer could refer to either the property of the struct or the parameter passed into the initializer. Swift uses self.age to clearly mean the property that belongs to the current instance , while plain age refers to the initializer parameter . So self.age = age means: assign the parameter value to the instance property.
That is why C is correct. The keyword self is required here to remove ambiguity between two identifiers with the same name.
The other options are incorrect:
* A is wrong because self here is not pointing to the parameter; it points to the instance property.
* B is wrong because self is not always required in every initializer assignment. It is specifically needed here because of the naming conflict.
* D is wrong because whether the property has a default value is not the reason self is needed in this example.
So the correct answer is C. self is needed to distinguish between the property and the parameter with the same name.
