i am using the following code for phone number validation. But i am getting the following error. I cant able to proceed further. Help us to take it forward.
class PhoneNumberValidation: Validation {
let PHONE_REGEX = "^\\d{3}-\\d{3}-\\d{4}$"
func validate(value: String) -> (Bool, ValidationErrorType) {
if let phoneTest = NSPredicate(format: "SELF MATCHES %@", PHONE_REGEX) {
if phoneTest.evaluateWithObject(value) {
return (true, .NoError)

return (false, .PhoneNumber)
}
return (false, .PhoneNumber)
}
}
Error : swift:15:28: Bound value in a conditional binding must be of Optional type

Yes your Error is below in XCode 6.1
This error is occurs because of if conditional have to Bool return type, but in Your if condition Return type is NSPredicate so that you got error swift: Bound value in a conditional binding must be of Optional type you can solve as below.
var phoneTest = NSPredicate(format: "SELF MATCHES %@", PHONE_REGEX)
if phoneTest.evaluateWithObject(value) {
return (true, .NoError)
}
return (false, .PhoneNumber)
}

do {
let detector = try NSDataDetector(types: NSTextCheckingType.PhoneNumber.rawValue)
let matches = detector.matchesInString(self, options: [], range: NSMakeRange(0, self.characters.count))

You can use simplified regex "^[6-9]\\d{9}$"
^ #Match the beginning of the string
[6-9] #Match a 6, 7, 8 or 9
\\d #Match a digit (0-9 and anything else that is a "digit" in the regex engine)
{9} #Repeat the previous "\d" 9 times (9 digits)
$ #Match the end of the string
Indian 10 Digit Mobile validation(can start with 6,7,8,9) -
extension String {
var isValidContact: Bool {
let phoneNumberRegex = "^[6-9]\\d{9}$"
let phoneTest = NSPredicate(format: "SELF MATCHES %@", phoneNumberRegex)
let isValidPhone = phoneTest.evaluate(with: self)
return isValidPhone
}
}
Usage:-
print("9292929292".isValidContact)//true
print("5454545454".isValidContact)//false

if isValidEmail(email.text) == false{

Updated version of iksnae's awesome answer. It's not a regex, but I think it's the best solution to validate all countries' phone numbers as it is smart enough to know if the country's phone extension code is valid as well.
extension String {
public var validPhoneNumber: Bool {
let types: NSTextCheckingResult.CheckingType = [.phoneNumber]
guard let detector = try? NSDataDetector(types: types.rawValue) else { return false }
if let match = detector.matches(in: self, options: [], range: NSMakeRange(0, self.count)).first?.phoneNumber {
return match == self
} else {
return false
}
}
}
print("\("+96 (123) 456-0990".validPhoneNumber)") //returns false, smart enough to know if country phone code is valid as well 🔥
print("\("+994 (123) 456-0990".validPhoneNumber)") //returns true because +994 country code is an actual country phone code
print("\("(123) 456-0990".validPhoneNumber)") //returns true
print("\("123-456-0990".validPhoneNumber)") //returns true
print("\("1234560990".validPhoneNumber)") //returns true
