IOS How to get String.range(of:string) multiple in swift

Question

MyText is

let myString: NSAttributedString = <siren> 123123 <siren> 123123 <siren>
let myRange = myString.string.range(of:"<siren>")
let newString = NSMutableAttributedString()
newString.append(myString)
if myRange != nil{
  newString.replaceCharacters(in: NSRange(myRange, in:myString.string), 
            with:myAttributeString as NSAttributedString!)
}

If myString has one <siren> this is worked, but it's not worked when it has more then two <siren>

replace only first <siren>

I think String.range return first value

how to find them all?

a) this isn't working code. b) don't start variables with uppercase letters, it makes it hard to determine classes from variables. Please update — Ashley Mills, Jul 04 '18 at 09:39

If you want to find all ranges you can try to use solution from this question get all ranges of a substring in a string in swift

but if your main purpose of that is replacing the occurrence of some string/pattern you can add an extension like that:

extension String {

  func replacing(pattern: String, withTemplate: String) throws -> String {
    let regex = try NSRegularExpression(pattern: pattern, options: .caseInsensitive)
    return regex.stringByReplacingMatches(in: self,
                                          options: [],
                                          range: NSRange(0 ..< utf16.count),
                                          withTemplate: withTemplate)
  }
}
