Invalid escape sequence in literal Swift 3.0 [duplicate]

Question

I have tried to print it but it just by passes because it's an escaped character. e.g output should be as follows.

\correct

Answer 1

For that and also future reference:

\0 – Null character (that is a zero after the slash)
\\ – Backslash itself.  Since the backslash is used to escape other characters, it needs a special escape to actually print itself.
\t  – Horizontal tab
\n – Line Feed
\r  – Carriage Return
\”  – Double quote.  Since the quotes denote a String literal, this is necessary if you actually want to print one.
\’  – Single Quote.  Similar reason to above.

Answer 2

Use the following code for Swift 5, Xcode 10.2

let myText = #"This is a Backslash: \"#
print(myText)

Output:

This is a Backslash: \

Now not required to add a double slash to use a single slash in swift 5, even now required slash before some character, for example, single quote, double quote etc.
