Standard Swift strings use double quotes, but you can’t include line breaks in there.
If you want multi-line strings you need slightly different syntax: start and end with three double quote marks, like this:
var str1 = """ This goes over multiple lines """
Swift is very particular about how you write those quote marks: the opening and closing triple must be on their own line, but opening and closing line breaks won’t be included in your final string.
If you only want multi-line strings to format your code neatly, and you don’t want those line breaks to actually be in your string, end each line with a
\, like this:
var str2 = """ This goes \ over multiple \ lines """
