Test: Swift - Variables and Constants

6. Which of the following is the preferred way in declaring a variable in Swift?

Congratulations! Correct Answer.
You Answered: None. If you took the test, your answer will show up here.
Correct Answer: var name = “infiniteZest.com”
While both are accurate, with option B, Swift can figure out (type inference) the type of the variable name. By looking at the string value assigned to it, Swift can say, name is of type String. That makes the code smaller and cleaner without losing any clarity. Hence, option B is the preferred way of declaring variables or constants in Swift.
