How to check if a text field is empty or not in swift

Question

I am working on the code below to check the textField1 and textField2 text fields whether there is any input in them or not.

The IF statement is not doing anything when I press the button.

 @IBOutlet var textField1 : UITextField = UITextField()  @IBOutlet var textField2 : UITextField = UITextField()  @IBAction func Button(sender : AnyObject)    {      if textField1 == "" || textField2 == ""        {    //then do something        }     }

Simply comparing the textfield object to the empty string "" is not the right way to go about this. You have to compare the textfield's text property, as it is a compatible type and holds the information you are looking for.

@IBAction func Button(sender: AnyObject) {     if textField1.text == "" || textField2.text == "" {         // either textfield 1 or 2's text is empty     } } 

Swift 2.0:

Guard:

guard let text = descriptionLabel.text where !text.isEmpty else {     return } text.characters.count  //do something if it's not empty 

if:

if let text = descriptionLabel.text where !text.isEmpty {     //do something if it's not empty       text.characters.count   } 

Swift 3.0:

Guard:

guard let text = descriptionLabel.text, !text.isEmpty else {     return } text.characters.count  //do something if it's not empty 

if:

if let text = descriptionLabel.text, !text.isEmpty {     //do something if it's not empty       text.characters.count   }
