Regex g is for global search

Question

I am using:

var test = "pizzazz"

if let match = test.range(of: "g/zz", options: .regularExpression) {
    print(test.substring(with: match))
}

This How do I set g for global search?

But "zz" only gives me "zz" There should be two - that is two ranges — Chris G., Apr 24 '17 at 14:06
Ok, I guess I have to use NSRegularExpression then. Like this on : http://stackoverflow.com/questions/27880650/swift-extract-regex-matches — Chris G., Apr 24 '17 at 14:11

I'm not sure what should be the result of your example, but you are probably looking for one of these functions:

1)

func enumerateMatches(in string: String, 
              options: NSRegularExpression.MatchingOptions = [], 
                range: NSRange, 
                using block: (NSTextCheckingResult?, NSRegularExpression.MatchingFlags, UnsafeMutablePointer<ObjCBool>) -> Void)

2)

func matches(in string: String, 
         options: NSRegularExpression.MatchingOptions = [], 
           range: NSRange) -> [NSTextCheckingResult]

3)

func stringByReplacingMatches(in string: String, 
                      options: NSRegularExpression.MatchingOptions = [], 
                        range: NSRange, 
                 withTemplate templ: String) -> String

4)

func replaceMatches(in string: NSMutableString, 
            options: NSRegularExpression.MatchingOptions = [], 
              range: NSRange, 
       withTemplate templ: String) -> Int
