i have been looking at the following (I am pretty new to IOS so any help would be gratefully appreciated).

How to convert string to MD5 hash using ios swift

And with the explanation of code used for Swift 2.2 from Hugo Alonso i am having problems actually using the function and declaring a string that is then hashed.

Code is below

struct MD5Digester {
// return MD5 digest of string provided
static func digest(string: String) -> String? {

    guard let data = string.dataUsingEncoding(NSUTF8StringEncoding) else { return nil }

    var digest = [UInt8](count: Int(CC_MD5_DIGEST_LENGTH), repeatedValue: 0)

    CC_MD5(data.bytes, CC_LONG(data.length), &digest)

    return (0..<Int(CC_MD5_DIGEST_LENGTH)).reduce("") { $0 + String(format: "%02x", digest[$1]) }
  }
}

Any help is appreciated.

Thanks

what specific kind of problem are your having? – Reinier Melian Jun 20 '16 at 20:29
Do you expect us to play detective to figure out what **your** problem is, or are you gonna tell us? – Alexander Jun 20 '16 at 20:40
sorry guys, thought i was being clear enough. So the above works however in that i don't get any build errors however i don't know how to use so that i supply a STRING which is then HASHED using the above code – ChinChaChee Jun 20 '16 at 20:44
You need to use `let md5string = MD5Digester.digest(@"string that you want to convert to MD5")` and in md5string you have your result? – Reinier Melian Jun 20 '16 at 20:53
Hey Reiner Melian now you have pointed it out its so obvious. Really appreciate your help with this. – ChinChaChee Jun 20 '16 at 21:00
Of course MD5 is not secure and should not be used in new code. – zaph Jun 20 '16 at 21:27
