Keyboard offset no longer functions in SwiftUI 2


So I have an ObservableObject that sets a published variable ‘currentHeight’ to the height of the keyboard:

import Foundation
import SwiftUI

class KeyboardResponder: ObservableObject {

@Published var currentHeight: CGFloat = 0

var _center: NotificationCenter

init(center: NotificationCenter = .default) {
    _center = center
    _center.addObserver(self, selector: #selector(keyBoardWillShow(notification:)), name: UIResponder.keyboardWillShowNotification, object: nil)
    _center.addObserver(self, selector: #selector(keyBoardWillHide(notification:)), name: UIResponder.keyboardWillHideNotification, object: nil)

@objc func keyBoardWillShow(notification: Notification) {
    if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        withAnimation {
           currentHeight = keyboardSize.height
    print("the KEYBOARD HEIGHT IS (self.currentHeight)")

@objc func keyBoardWillHide(notification: Notification) {
    withAnimation {
       currentHeight = 0
    print("the KEYBOARD HEIGHT IS (self.currentHeight)")

In my other views, I create an ObservedObject keyboardResponder and then inside the body of the view, I’ll have for example some view where I set the vertical offset:

struct ViewName: View {
    @ObservedObject var keyboardResponder = KeyboardResponder()
    var body: some View {
        VStack {
            Text("this should be offset")
            .offset(y: -keyboardResponder.currentHeight)

Before Xcode 12/SwiftUI 2 dropped, this worked like a charm but I think they changed something with how views refresh–anyone know what they changed and if there is a solution to my issue here?

As of the latest Swift, Xcode 12 and iOS14, I noticed that it is standard build in, when the textfield is not visible when typing. The screen is being risen with the keyboard height and shows the original field. Try this out with a scrollable view and 20 textfields for example.
Maybe you can get rid of your observableheight and do it without hard coding it.
