Replacing Text

Replacing a repeated substring can make compact text easier to display.

Replace delimiters

replacing_text.swift 
import Foundation

let replacement = 
let raw = "red,green,blue"
let changed = raw.replacingOccurrences(of: ",", with: replacement)
let message = changed

print(message)

import Foundation

let replacement = 
let raw = "red,green,blue"
let changed = raw.replacingOccurrences(of: ",", with: replacement)
let message = changed

print(message)

import Foundation

let replacement = 
let raw = "red,green,blue"
let changed = raw.replacingOccurrences(of: ",", with: replacement)
let message = changed

print(message)
text replacement `replacingOccurrences` returns text with every matching piece changed to the replacement string.
