Register the fields that you want to validate

super.viewDidLoad()
// Validation Rules are evaluated from left to right.
validator.registerField(fullNameTextField, rules: [RequiredRule(), FullNameRule()])
// You can pass in error labels with your rules
validator.registerField(emailTextField, errorLabel: emailErrorLabel, rules: [RequiredRule(), EmailRule()])
// You can validate against other fields using ConfirmRule
validator.registerField(emailConfirmTextField, errorLabel: emailConfirmErrorLabel, rules: [ConfirmationRule(confirmField: emailTextField)])
// You can now pass in regex and length parameters through overloaded contructors
validator.registerField(phoneNumberTextField, errorLabel: phoneNumberErrorLabel, rules: [RequiredRule(), MinLengthRule(length: 9)])
validator.registerField(zipcodeTextField, errorLabel: zipcodeErrorLabel, rules: [RequiredRule(), ZipCodeRule(regex = "\\d{5}")])
