I'm having trouble disabling keyboard avoidance for a SwiftUI view that is embedded in a UIHostingController. When the UITextField becomes first responder, the SwiftUI view jumps out of the way for the keyboard, and I want it to stay in place. To test this out, set the ViewController as the rootViewController in a UIKit App Delegate. import SwiftUI struct ContentView: View {     var body: some View {         Text("I want this text to stay put.") /* THIS DOESN'T WORK         .ignoresSafeArea(.keyboard) */     } } class ViewController: UIViewController {     override func viewDidLoad() {         super.viewDidLoad()         let textField = UITextField(frame: CGRect(x: 10, y: 100, width: 200, height: 50))         textField.backgroundColor = .white         textField.placeholder = "Tap here!"         view.addSubview(textField)         let button = UIButton(type: .system, primaryAction: UIAction(title: "Dismiss Keyboard", handler: { _ in             textField.resignFirstResponder()         }))         button.frame = CGRect(x: 220, y: 100, width: 140, height: 50)         view.addSubview(button)         let hostingController = UIHostingController(rootView: ContentView())         hostingController.view.frame = CGRect(x: 10, y: UIScreen.main.bounds.size.height - 510, width: UIScreen.main.bounds.size.width - 20, height: 500)         view.addSubview(hostingController.view)     } }

As described in "The details of UI typography," the system font is now variable, implicating that its weight can be scaled between standard values from 100 - 900. Is there a way I can achieve this in UIKit? My overall goal is to animate text from one standard font weight to another.
