No.

Either use verbatim string literals as you have, or escape the " using backslash.

string test = "He said to me, \"Hello World\" . How are you?";

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

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

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

let sentence = """

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)"#

This will give the MyVar variable a value of some text "hello" hello.
