Programmatically go back to previous ViewController in Swift
Swift 3:
If you want to go back to the previous view controller
_ = navigationController?.popViewController(animated: true)If you want to go back to the root view controller
_ = navigationController?.popToRootViewController(animated: true)If you are not using a navigation controller then pls use the below code.self.dismiss(animated: true, completion: nil)
Swift 3
I might be late in the answer but for swift 3 you can do it this way:
override func viewDidLoad() { super.viewDidLoad() navigationItem.leftBarButtonItem = UIBarButtonItem(title: "< Back", style: .plain, target: self, action: #selector(backAction)) // Do any additional setup if required.}func backAction(){ //print("Back Button Clicked") dismiss(animated: true, completion: nil)}
