Declaration
init(stringInterpolation: DefaultStringInterpolation )
Discussion
Do not call this initializer directly. It is used by the compiler when you create a string using string interpolation. Instead, use string interpolation to create a new string by including values, literals, variables, or expressions enclosed in parentheses, prefixed by a backslash (\(…)).
let price = 2
let number = 3
let message = """
If one cookie costs \(price) dollars, \
\(number) cookies cost \(price * number) dollars.
"""
print(message)
// Prints "If one cookie costs 2 dollars, 3 cookies cost 6 dollars."
