Swift 에서 regex 사용하는 코드

Bool { let matches = self.getMatchesWithRegex(regex) return matches.count > 0 } }"> Bool { let matches = self.getMatchesWithRegex(regex) return matches.count > 0 } }"> Bool { let matches = self.getMatchesWithRegex(regex) return matches.count > 0 } }">

extension String {	
	func getMatchesWithRegex(_ regex: String) -> [String] {
	  do {
	    let regex = try NSRegularExpression(pattern: regex)
	    let results = regex.matches(in: self, range: NSRange(self.startIndex..., in: self))
	    return results.map({
	      String(self[Range($0.range, in: self)!])
	    })
	  } catch {
	    fatalError("regex 문자가 잘못되었습니다. \\(regex)")
	  }
	}
	
	func foundMatchesWithRegex(_ regex: String) -> Bool {
	  let matches = self.getMatchesWithRegex(regex)
	  return matches.count > 0
	}
}
