how to remove first character from textfield value in swift-CodePudding

if my textfield takes 11 characters then i need to remove first character and then pass it to jason perameter, so i tried like below

var dropFirst: String?
if emailPhoneTextField.text?.count == 11{
    dropFirst = emailPhoneTextField.text?.dropFirst()
        emailPhoneTextField.text = dropFirst 
    }

then o/p: then error, how to fix

Cannot assign value of type 'String.SubSequence?' (aka 'Optional') to type 'String?'

CodePudding user response：

dropFirst returns SubSequence so you can't assign it directly to textfield's text property that accepts an optional string (String?) , So replace

dropFirst = emailPhoneTextField.text?.dropFirst()

With

dropFirst = String(emailPhoneTextField.text!.dropFirst())
