Do u also got same error in the swift lesson 'optional'?

Question

In swift course, lesson name optional variable, in practical session asking to declare a optional variable, when I check the correct answer it shows an optional variable with the name - test,
but when I try to declare the variable with another name it shows an error - wrong answer...
It should be fixed.

Answer 1

Yeah I used to do course on its website. As they updated it. I lost my course progress..
Your question's solution is
Declare optional variable of name - 'test' of string data type.

Answer 2

I am stuck in that question too. I stop my learning in Swift 4 after that. I mean, there are no clue for that question.

Answer 3

var test: String?
