I am trying to check if a textbox has no value.
When I do this:
if(userEmail?.isEmpty || userPassword?.isEmpty || userPasswordRepeat?.isEmpty)
Try this....
if txtEmail.text?.isEmpty == true || txtPassword.text?.isEmpty == true || txtRePassword.text?.isEmpty == true{
print("true")
}
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
}
