App.Delegate from ViewController to TabController Swift 5

Question

My code does not work in Swift 5

var myTabBar = self.storyboard?.instantiateViewController(withIdentifier: "myTabBar") as! UITabBarController
var app = UIApplication.shared.delegate as! AppDelegate
app.window?.rootViewController = myTabBar

Value of type AppDelegate has no member window

I'm meeting you more than half-way here, because we really need more details on what's going on and what you're trying to achieve.

But the error is telling you that the AppDelegate doesn't have a variable called window. You probably want the UIApplication object itself, and not its delegate.

Maybe try replacing

var app = UIApplication.shared.delegate as! AppDelegate
app.window?.rootViewController = myTabBar

with

var app = UIApplication.shared
app.keyWindow?.rootViewController = myTabBar
