Removing line breaks from string

Question

I have a string like so:

var aString = "This is a string \n\n This is the second line of the string\n\n"

Which inside a textview looks like so:

This is a string 

This is the second line of the string


// 2 extra lines of unnecessary white space

But i want it to look like this:

This is a string 
This is the second line of the string

I want to remove all "\n" from the end of the string and remove \n where it repeats itself so theres no white space in the middle.

ideally, I'm guessing the end result should be this:

var aString = "This is a string \n This is the second line of the string"

Answer 1

The basic idea for your code would be replacing all double /n with a single /n.

var aString = "This is my string"
var newString = aString.replacingOccurrences(of: "\n\n", with: "\n")

Answer 2

what about this?

var aString = "This is a string \n\n\n This is the second line of the string\n\n"
// trim the string
aString.trimmingCharacters(in: CharacterSet.newlines)
// replace occurences within the string
while let rangeToReplace = aString.range(of: "\n\n") {
    aString.replaceSubrange(rangeToReplace, with: "\n")
}
