What is the proper way to dismiss a modal when using storyboards?

Question

Using storyboards, what is the proper way to dismiss a modal?

• using IBAction and writing code to dismiss after a button click?
• using segue and notify the parent view controller after a button click?

Answer 1

See Here Dismissing a Presented View Controller about halfway down

When it comes time to dismiss a presented view controller, the preferred approach is to let the presenting view controller dismiss it.

So you should use an IBAction and writing code to dismiss after a button click

Answer 2

According Alex Cio answer for Swift 3 and XCode 8.3:

Create class:

import UIKit  class DismissSegue: UIStoryboardSegue {     override func perform() {         self.source.presentingViewController?.dismiss(animated: true, completion: nil)    } } 

But in storyboard you should choose:

Action Segue -> Custom -> dismiss

Only after this option appear on Action Segue menu
