How do you make raw strings in Swift?
Swift version: 5.6
Raw strings place hash signs – # – before and after their quote mark, and modify the way Swift handles strings in two ways.
First, a string that starts with #" must end with a "#, which means any quote marks inside the string are ignored:
let string1 = #"The rain in "Spain" falls mainly on the Spaniards"#Second, any escape sequences – things that start with \ – now have their regular meaning. So, this will print one line of text:
let string2 = #"The rain\nin Spain\nfalls mainly\non the Spaniards"#With a regular Swift string the instances of \n would have been interpreted as line breaks.
If you want to use escape characters, for example if you want to use string interpolation, you must use \#(yourValue), like this:
let name = "Duane Dibbley"
print(#"Hello! My name is \#(name)."#)
