I want to check the validation for both mobile number and email id in single textfield. How should I validate this? - swift

Question

I want to check the validation for both "Email id " and "mobile number" in single textfield. How should I validate the conditions for the same textfield?

Answer 1

Maybe this will help:
extension String {
var isPhoneNumber: Bool {
do {
let detector = try NSDataDetector(types: NSTextCheckingResult.CheckingType.phoneNumber.rawValue)
let matches = detector.matches(in: self, options: [], range: NSMakeRange(0, self.count))
if let res = matches.first {
return res.resultType == .phoneNumber && res.range.location == 0 && res.range.length == self.count
} else {
return false
}
} catch {
return false
}
}
}
extension String {
var isInt: Bool {
return Int(self) != nil
}
}
func isValidEmail(testStr:String) -> Bool {
let emailRegEx = "[A-Z0-9a-z._%+-]+#[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"
let emailTest = NSPredicate(format:"SELF MATCHES %#", emailRegEx)
return emailTest.evaluate(with: testStr)
}
if textField.text.characterCount > 6 {
if textField.text.isInt == true {
print("this might be users phone number"
} else if isValidEmail(testStr:textField.text) {
print("this might be users mail")
} else {
print("user entered wrong value or nothing")
}
