How will you require user input

Question

Asking for user input

Answer 1

You use the
readLine()
function, which will return an optional string. So, you also need to unwrap it using the bang operator '!'.

Answer 2

Calvin Thomas I don't think it actually is mentioned in the Swift course. The course is designed around building an iOS app and not so much a console app. It is also quite dated at this point as there is a much newer and updated version of Swift. Some of the code in the course is no longer valid for the newest version of Swift.

Answer 3

ChaoticDawg Oh, I'm sorry for that. I had thought that this was there in Swift.

Answer 4

Khar Wonder I guess that this has been clearly mentioned in the course.
