Courses Plus Student 2,728 PointsDo I have to put quotation marks around a string?
Just a quick question I had.

Treehouse TeacherYes. If you don't put quotation marks around a string, Swift is going to believe you're talking about another variable. It needs a way to differentiate between these two things:
var x = "aString"
var y = x
var z = aString
In the first line I assign the string "aString" to x. In the second, I assign the value of the variable x to y. The variable y will now also contain "aString". In the last line, though, you will receive an error because it's looking for a variable named aString
, which doesn't exist.
Hope this helps!
