Checking if text fields are empty cause error in Swift 2

I am trying to check if a textbox has no value.

When I do this: 

if(userEmail?.isEmpty || userPassword?.isEmpty || userPasswordRepeat?.isEmpty)

I get the following error enter image description here

I tried adding "?" before the ".isEmpty" but the error won't go away enter image description here

Any ideas?

If interested also in positive case, the following is an alternative solution for Swift 2:

let email = self.txtEmail.text where !email.isEmpty, let password = self.txtPassword.text where !password.isEmpty {
    //all fields are not nil && not empty
}else{
    //some field is nil or empty
}

Try this.... 

if txtEmail.text?.isEmpty == true || txtPassword.text?.isEmpty == true || txtRePassword.text?.isEmpty == true{
        print("true")
}
