I am trying to run the code below:
import UIKit
class LoginViewController: UIViewController {
@IBOutlet var username : UITextField = UITextField()
@IBOutlet var password : UITextField = UITextField()
@IBAction func loginButton(sender : AnyObject) {
if username .isEqual("") || password.isEqual(""))
{
println("Sign in failed. Empty character")
}
}
My previous code was in Objective-C, which was working fine:
if([[self.username text] isEqualToString: @""] ||
[[self.password text] isEqualToString: @""] ) {
I assume I cannot use isEqualToString
in Swift. Any help would be appreciated.
Best Answer
With Swift you don't need anymore to check the equality with
isEqualToString
You can now use
==
Example:
now isEqual is
true
.
