The question is totally different from the duplicated one. OP is asking "before any Special character" not before a specific character — Leo Dabus, Apr 26 '20 at 17:27

You can use a regular expression to match any special character "[^\\w]" which means any non word character and replace by the same match "$0"preceded by white spaces. If you would like to exclude whitespaces from being replaced you can use "[^\\w|\\s]":

let str =  "#StackOverFlow#is#awesome"
let result = str.replacingOccurrences(of: "[^\\w]",
                          with: "   $0",
                          options: .regularExpression)


print(result)  // "   #StackOverFlow   #is   #awesome\n"

let str2 =  "•StackOverFlow•is•awesome"
let result2 = str2.replacingOccurrences(of: "[^\\w]",
                          with: "   $0",
                          options: .regularExpression)


print(result2)  // "   •StackOverFlow   •is   •awesome\n"
