Xcode SwiftUI转UIKit界面后大小异常怎么解决？

Question

//Xcode SwiftUI转UIKit界面后，界面大小异常，所有组件变得比之前大
转换代码:
import UIKit
import SwiftUI

class ViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    // Hiding Nav Bar...
    //self.navigationController?.navigationBar.isHidden = true
    extractView()
}

//Extracting SwiftUI View And Setting to UIkit View...
func extractView(){
    
    let hostView = UIHostingController(rootView: Home())
    hostView.view.translatesAutoresizingMaskIntoConstraints = false
    
    self.view.addSubview(hostView.view)
    
    // Constraints...
    // Clipping SwiftUI View to UIkit View...
    let constraints = [
        
        hostView.view.topAnchor.constraint(equalTo: view.topAnchor),
        hostView.view.bottomAnchor.constraint(equalTo: view.bottomAnchor),
        hostView.view.leadingAnchor.constraint(equalTo: view.leadingAnchor),
        hostView.view.trailingAnchor.constraint(equalTo: view.trailingAnchor),
        
        // Height And Width...
        hostView.view.widthAnchor.constraint(equalTo: view.widthAnchor),
        hostView.view.heightAnchor.constraint(equalTo: view.heightAnchor),
    ]
    
    self.view.addConstraints(constraints)
}

}
