 We will create a ```SSNRule``` class to show how to create your own Validation. A United States Social Security Number (or SSN) is a field that consists of XXX-XX-XXXX. 
 
-Create a class that implements the Rule protocol
+Create a class that inherits from RegexRule
 
 ```swift
 
-class SSNVRule: Rule {
-    let REGEX = "^\\d{3}-\\d{2}-\\d{4}$"
