how can i convert NSString to String

Question

Im trying to convert a NSString from a text field to a standard String so that I can check if it contains a certain character.

I have tried

var nSStringText = textField.text! as NSString
var stringText = nSStringText as String

output

'NSString' is not convertible to 'String'

Answer 1

let myNSString: NSString = "I'm iOSDev"
let myString: String = myNSString as String
print(myString)
print(myString.isEmpty)

Casting Refer to myNSString as String

Also, You don't need to cast textField text as NSString it's by default String So, Just use

var myString: String = myTextField.text ?? ""

NSString and String are bridged. You don't need to, and can't, cast from one to the other. As vacawama says in his comment, a UITextField's text property is already of types String.
