How to remove all the spaces and \n\r in a String?

Question

What is the most efficient way to remove all the spaces, \\n and \\r in a String in Swift?

I have tried:

for character in s         


        

Answer 1

If anyone is wondering why, despite of putting "\n" and "\r" into the set, "\r\n" is not removed from the string, it's because "\r\n" is treated by swift as one character.

Swift 4:

let text = "\r\n This \n is a st\tri\rng"
let test = String(text.filter { !"\r\n\n\t\r".contains($0) })

"\n" is not duplicated by accident
