ios – SwiftUI Views are shifting after being loaded (the peak is altering)

So I’m utilizing a swiftUI view inside UIKit utilizing UIHostingController . That is the code for that half

class ProductCardViewController: UIViewController {
  var purchaseResult: PurchaseResult = .failure

  override func viewAppearance() {
    tremendous.viewAppearance()
      let productCardVc: UIHostingController
    change purchaseResult {
    case .success:
       let productCardVc = UIHostingController(rootView: AnyView(ProductCardView()))
    case .failure:
        productCardVc = UIHostingController(rootView: AnyView(ProductPurchaseFailureView(navigationController: navigationController)))
    }
    setupHostingController(productCardVc)
  }

  personal func setupHostingController(_ hostingController: UIHostingController) {
    hostingController.view.bounds = view.bounds
    hostingController.view.backgroundColor = .clear
    hostingController.view.translatesAutoresizingMaskIntoConstraints = false
    view.addSubview(hostingController.view)

    NSLayoutConstraint.activate([
      hostingController.view.topAnchor.constraint(equalTo: view.topAnchor),
      hostingController.view.bottomAnchor.constraint(equalTo: view.bottomAnchor),
      hostingController.view.leadingAnchor.constraint(equalTo: view.leadingAnchor),
      hostingController.view.trailingAnchor.constraint(equalTo: view.trailingAnchor)
    ])
  }
  
}

However when my swiftUI View hundreds there’s a change in top of the geomatry of the view from top 852 to top 759. I do not know why that is taking place .

My SwiftUI view

import SwiftUI
import Lottie

struct ProductPurchaseFailureView: View {
    var navigationController: UINavigationController?
    var physique: some View {
        GeometryReader { geometry in
            ZStack() {
                Picture("random_image")
                    .resizable()
                    .opacity(0.3)
                    .blur(radius: 150)
                    .background(Colour.purchaseFailureBackground)
                    .ignoresSafeArea()
                
                ZStack {
                  Textual content("Scratch Card")
                    .font(.customized(FontConstants.therokBold.rawValue, measurement: 28))
                    .foregroundColor(.white)
                    .shadow(coloration: .black, radius: 2, x: 1, y: 2)

I do not perceive the place I’m doing mistaken. I’m very new to SwiftUI and have solely labored with UIKit . Please assist guys
