The first step to using Xib instead of StoryBoard
environment
Xcode12.3
goal
Remove StoryBoard and launch it from Xib.
Create a project

Select ViewController.Swift and Main.storyBoard> Right click> Delete> Move to Trash
Info.plist settings
(1) Main storyboard file base name> Delete
(2) Application Scene Manifest> Scene Configuration> Application Session Role> Item 0 (Default Configuration)> Storyboard Name> Delete
Create ViewController and Xib files
New File> Cocoa Touch Class> Subclass of: UIViewContoroller> Also create Check XIB file> Next> Create
I was able to create two files.
This time, set the background to blue so that it is easy to understand when starting up.
Set SceneDelegate.swift
Set the screen displayed at startup with func scene (_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) to ViewContoroller that supports Xib files.
SceneDelegate.swift
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
guard let _ = (scene as? UIWindowScene) else { return }
//Postscript from here
let window = UIWindow(windowScene: scene as! UIWindowScene)
self.window = window
window.makeKeyAndVisible()
let xibViewController = XibViewController()
window.rootViewController = xibViewController
}
Start the simulator
The Xib with the blue background that I set earlier has started up firmly.
