UIHostingController inside UIView bug when moving

UIHostingController (text with purple background) is not following it's parent container (blue UIView), even though it has all the constraints to match the parent.

  • The blue view is a UIView
  • The blue view bottomAnchor is pinned to the keyboardLayoutGuide.topAnchor and has a fixed height.
  • The text "Hello I'm here!" with purple background is a SwiftUI view
  • I added the SwiftUI view inside the blue view like the following:
    let vc = UIHostingController(rootView: CustomText())
    vc.didMove(toParent: self)
    vc.view.translatesAutoresizingMaskIntoConstraints = false
    vc.view.topAnchor.constraint(equalTo: blueView.topAnchor).isActive = true
    vc.view.bottomAnchor.constraint(equalTo: blueView.bottomAnchor).isActive = true
    vc.view.leadingAnchor.constraint(equalTo: blueView.leadingAnchor).isActive = true
    vc.view.trailingAnchor.constraint(equalTo: blueView.trailingAnchor).isActive = true
