Validation du courrier électronique et du téléphone dans Swift
j'utilise le code suivant pour la validation du numéro de téléphone. Mais je reçois l'erreur suivante. Je ne peux pas continuer plus loin. Aidez-nous à le faire avancer.

Erreur: Swift: 15: 28: La valeur liée dans une liaison conditionnelle doit être de type facultatif.
Oui, votre erreur est ci-dessous dans xcode 6.1
Cette erreur est due au fait que IF conditionnel a le type de retour Bool, mais que dans Your si le type de retour est NSPredicate, de sorte que vous obtenez une erreur Swift: La valeur liée dans une liaison conditionnelle doit être de type facultatif vous pouvez le résoudre en tant que au dessous de.

Le code suivant fonctionne dans xcode 6.3 beta
func isValidEmail(testStr:String) -> Bool {
let emailRegEx = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}"
let range = testStr.rangeOfString(emailRegEx, options:.RegularExpressionSearch)
let result = range != nil ? true : false
return result
}
comment l'utiliser:
Ex.
if isValidEmail(email.text) == false{
//your code here
}
Swift 4+
Vous pouvez utiliser regex"^[6-9]\\d{9}$" simplifié
^ #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

extension String {
var isValidContact: Bool {
let phoneNumberRegex = "^[6-9]\\d{9}$"
let phoneTest = NSPredicate(format: "SELF MATCHES %@", phoneNumberRegex)
let isValidPhone = phoneTest.evaluate(with: self)

Fichier-Nouveau-Fichier.Faites une classe Swift nommée AppExtension.Add ce qui suit.
extension UIViewController{
func validateEmailAndGetBoolValue(candidate: String) -> Bool {

Use:
var emailValidator:Bool?
self.emailValidator = self.validateEmailAndGetBoolValue(resetEmail!)
print("emailValidator : "+String(self.emailValidator?.boolValue))
Use a loop to alternate desired results.
OR
extension String
