Remove the unwanted charaters in a phone Number iOS swift

-
Solution:

 You can get the phone number from the user in textfield and format it as a valid phone number using the below expression.


 let ValidNo = number.value.stringValue.replacingOccurrences(of: "[^0-9+]", with: "", options: NSString.CompareOptions.regularExpression, range:nil)



The above expression will truncate the special characters in the phone Number.So you can save the phone number directly to your database.
