Apple App Development with Swift Certified User Sample Questions:
Review the code.
Note: You might need to scroll to see the entire block of code.
A breakpoint is set on line 3. When the application is run. it will stop at line 3. You need to debug the code.
Drag each debugging control from the left to the correct instruction on the right. You will receive partial credit for each correct answer
Explanation:
This question belongs to Xcode Developer Tools , especially the objective on using debugging techniques including breakpoints and stepping controls .
When execution stops at a breakpoint on line 3, Step Over runs that line without entering into another function call, so it is the correct action for moving past line 3 while staying in the current function. Step Into is used when execution reaches line 4 and you want to enter the display(numbers) function, which takes you into the function body starting at line 8. Once inside that function, Step Out continues execution until the current function returns, which is exactly what "step out from line 8" means.
Deactivate breakpoints turns breakpoint handling off so the debugger no longer stops on active breakpoints.
Continue program execution resumes the app until the next breakpoint or until the program finishes.
So the correct control order is:
1 = Continue
2 = Deactivate breakpoints
3 = Step Over
4 = Step Into
5 = Step Out
Review the code snippet.
Which statement completes the code snippet so that:
* The lastReleaseDate remains the same when nextApplePhone.releaseDate is nil.
* The lastReleaseDate updates to the nextApplePhone.releaseDate when nextApplePhone.releaseDate is NOT nil.
- A. nextApplePhone.releaseDate : lastReleaseDate
- B. lastReleaseDate : nextApplcPhone.rcleaseDate!
- C. lastReleaseDate : nextApplePhone.releaseDate
- D. nextApplePhone.releaseDate! : lastReleaseDate

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.
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.
Review the code snippet.
The code snippet does not compile.
Which two actions will fix the errors? (Choose 2.)
- A. Change shipping from let to var to make it mutable.
- B. Change the initial value of totalCost from o to 0.0.
- C. Chang the type of unitPrice from Double to Int.
- D. Change totalCost from let to var to make it mutable.
- E. Change the type of quantity from int to Double .

Given the function, which two function calls are valid? (Choose 2.)
- A. let sum r\ ght5um(100, by: 50)

- C. let sum = rightSum(100, num2: SO, and: 20)
- D. let sum - rightSum(100, by: 30, and: 20)
- E. let sun = rightSum(numl: 100, num2: 50)
