swift - How to print double quotes inside ""?

Question

Can someone please tell me how can I print something in following way "with" double quotes.

"Double Quotes"

Answer 1

With a backslash before the double quote you want to insert in the String:

let sentence = "They said "It's okay", didn't they?"

Now sentence is:

They said "It's okay", didn't they?

It's called "escaping" a character: you're using its literal value, it will not be interpreted.

With Swift 4 you can alternatively choose to use the """ delimiter for literal text where there's no need to escape:

let sentence = """
They said "It's okay", didn't they?
Yes, "okay" is what they said.
"""

This gives:

They said "It's okay", didn't they?
Yes, "okay" is what they said.

With Swift 5 you can use enhanced delimiters:

String literals can now be expressed using enhanced delimiters. A string literal with one or more number signs (#) before the opening quote treats backslashes and double-quote characters as literal unless they’re followed by the same number of number signs. Use enhanced delimiters to avoid cluttering string literals that contain many double-quote or backslash characters with extra escapes.

Your string now can be represented as:

let sentence = #"They said "It's okay", didn't they?"#

And if you want add variable to your string you should also add # after backslash:

let sentence = #"My "homepage" is #(url)"#
