How to perform a segue programmatically using performSegue()

Swift version: 5.0

Paul Hudson    @twostraws   

Segues are a visual way to connect various components on your storyboard, but sometimes it’s important to be able to trigger them programmatically as well as after a user interaction.

Fortunately, it only takes two steps. First, select a segue in your storyboard, then go to the attributes inspector and give it a name such as “showDetail”.

Now head to your Swift code, to the place where you want to trigger the segue you just named. The method you need to call is performSegue(), which exists on all view controllers: pass it a segue identifier as well as whatever object you want to send along, and you’re done:

performSegue(withIdentifier: "showDetail", sender: nil)

Technically the sender parameter is whatever triggered the segue, but you can put whatever you want in there.
