Swift - Split string over multiple lines

Question

How could I split a string over multiple lines such as below?

var text:String = \"This is some text
                   over multiple lines\"

Answer 1

One approach is to set the label text to attributedText and update the string variable to include the HTML for line break (<br />).

For example:

var text:String = "This is some text<br />over multiple lines"
label.attributedText = text

Output:

This is some text
over multiple lines

Hope this helps!

The following example depicts a multi-line continuation, using parenthesis as a simple workaround for the Swift bug as of Xcode 6.2 Beta, where it complains the expression is too complex to resolve in a reasonable amount time, and to consider breaking it down into smaller pieces:

    .
    .
    .
    return String(format:"\n" +
                    ("    part1:    %d\n"    +
                     "    part2:    %d\n"    +
                     "    part3:  \"%@\"\n"  +
                     "    part4:  \"%@\"\n"  +
                     "    part5:  \"%@\"\n"  +
                     "    part6:  \"%@\"\n") +
                    ("    part7:  \"%@\"\n"  +
                     "    part8:  \"%@\"\n"  +
                     "    part9:  \"%@\"\n"  +
                     "    part10: \"%@\"\n"  +
                     "    part12: \"%@\"\n") +
                     "    part13:  %f\n"     +
                     "    part14:  %f\n\n",
                    part1, part2, part3, part4, part5, part6, part7, part8, 
                    part9, part10, part11, part12, part13, part14)
    .
    .
    .

Answer 3

You can using unicode equals for enter or \n and implement them inside you string. For example: \u{0085}.

Answer 4

Swift:

@connor is the right answer, but if you want to add lines in a print statement what you are looking for is \n and/or \r, these are called Escape Sequences or Escaped Characters, this is a link to Apple documentation on the topic..

Example:

print("First line\nSecond Line\rThirdLine...")

Answer 5

Adding to @Connor answer, there needs to be \n also. Here is revised code:

var text:String = "This is some text \n" +
                  "over multiple lines"

Answer 6

Multi-line strings are possible as of Swift 4.0, but there are some rules:

1. You need to start and end your strings with three double quotes, """.
2. Your string content should start on its own line.
3. The terminating """ should also start on its own line.

Other than that, you're good to go! Here's an example:

let longString = """
When you write a string that spans multiple
lines make sure you start its content on a
line all of its own, and end it with three
quotes also on a line of their own.
Multi-line strings also let you write "quote marks"
freely inside your strings, which is great!
"""
