Checking if text fields are empty cause error in Swift 2

Question

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

When I do this:

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


        

Answer 1

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
}
