Answer 1

helpful when getting value from UITextField and checking for nil & empty string

@IBOutlet weak var myTextField: UITextField!

Heres your function (when you tap on a button) that gets string from UITextField and does some other stuff

@IBAction func getStringFrom_myTextField(_ sender: Any) {

guard let string = myTextField.text, !(myTextField.text?.isEmpty)!  else { return }
    //use "string" to do your stuff.
}

This will take care of nil value as well as empty string.

It worked perfectly well for me.
