Environment Object Method error in Scene Delegate - mvvm

Question

SO Community
I have been self-teaching myself SwiftUI and I've just come across a problem while creating an application in the Scene Delegate. When I add an environment object method to the scene delegate to assign an object to the environment of a view hierarchy, Xcode sends these errors on my let contentView = ContentView().environmentObject(delegate.myData) line of code, "Expected member name following '.' ", and "Missing argument for parameter 'appData' in call ".
I will also attach a picture of my ContentView.swift File to show where I placed my #EnviromentObject reference within the body Content View. If you guys have any questions can you please try to help me out, this has been a bum time. Thanks.

class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options
connectionOptions: UIScene.ConnectionOptions) {
let app = UIApplication.shared
let delegate = app.delegate as! AppDelegate
let contentView = ContentView()
.environmentObject(delegate.myData)
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: contentView)
self.window = window
window.makeKeyAndVisible()
}
}

EnvironmentObjects are not passed via parameter like you're trying to do in your ContentView initializer. Instead, they are passed "magically" behind-the-scenes and exposed via the #EnvironomentObject property wrapper.
My suggestion is to get rid of your init method and use onAppear { } to set your contentData fields:
var body: some View {
VStack {
//...
}.onAppear {
// do initial setup
}
}
You should also make sure that you're using the same capitalization of appData -- you're using appdata sometimes, which is leading to many of your compilation errors.
