I have used this delegate method but it's not returning last character which I entered.
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool
Eg. Current Text field string is "123" and when I enter "4", so textfield string is "1234" but above delegate method return only "123", now again entered "5" then above method return "1234" but I'm expecting "12345"
But later I found the solution which works for me
Swift 5
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
var finalString = ""
if range.length > 0 {
finalString = "\(textField.text!.dropLast())"
} else {
finalString = "\(textField.text! + string)"
}
print(finalString)
return true
}
