When looking at this article - AppDelegate in SwiftUI, and adapting it to WatchOS, I am still unsure how to access the delegate within other classes. I used to be able to use a version of this - let delegate = WKExtension.shared().delegate as! ExtensionDelegate, but this tries to access withe default SwiftUI.ExtensionDelegate. How to I get swift to accessmy custom extension Delegate?

Instead of using ExtensionDelegate use your own custom class name here?

Having the same issue and still was not able to figure out. @Hatsushira ExtensionDelegate IS the name of my custom class.
