  • Replacing regular expression matches with template string. Could use self.replacingOccurrences(of: pattern, with: template, options: .regularExpression)

    Declaration

    Swift

    func replacingMatches(
  of pattern: String,
  options: NSRegularExpression.Options = [],
  matchingOptions: NSRegularExpression.MatchingOptions = [],
  with template: String
) throws -> String

  • Returns matched strings of a regular expression pattern.

    Declaration

    Swift

    func matchedStrings(
  of pattern: String,
  options: NSRegularExpression.Options = [],
  matchingOptions: NSRegularExpression.MatchingOptions = []
) -> [String]

  • Undocumented

    Declaration

    Swift

    func firstMatchedString(of pattern: String,
                        options: NSRegularExpression.Options = [],
                        matchingOptions: NSRegularExpression.MatchingOptions = []) -> String?

  • Returns captured groups of a regular expression pattern for provided match index.

    Declaration

    Swift

    func capturedGroups(
  of pattern: String,
  options: NSRegularExpression.Options = [],
  matchingOptions: NSRegularExpression.MatchingOptions = [],
  matchIndex: Int = 0
) -> [String]
