Connecting iOS AppDelegate, SceneDelegate, and ViewController

Avoid Non Programming Interfaces in the Project

When we create a Story iOS App Project, we will get a few files automatically generated as below.

Only 3 Swift classes i.e. AppDelegate, SceneDelegate and ViewController. There are 2 Storyboards and one info.plist, the accessories that help connect them up.

From the diagram, we can see the Swift codes are not tied to one another. This makes it harder to control them programmatically.

Therefore, here I’m sharing how to programmatically hook them up.

1. Hook up AppDelegate with SceneDelegate

When we see the info.plist, we can see it is used to connect to both the SceneDelegate and also the Main storyboard.
