How to ignore safe area in UIHostingController

UIHostingController+SafeArea.swift

import SwiftUI

extension UIHostingController {

    convenience public init(rootView: Content, ignoreSafeArea: Bool) {
        self.init(rootView: rootView)

        if ignoreSafeArea {
            disableSafeArea()
        }
    }

    func disableSafeArea() {
        guard let viewClass = object_getClass(view) else {
            return
        }

        let viewSubclassName = String(cString: class_getName(viewClass)).appending("_IgnoreSafeArea")

        if let viewSubclass = NSClassFromString(viewSubclassName) {
            object_setClass(view, viewSubclass)
        } else {
            guard 
                let viewClassNameUtf8 = (viewSubclassName as NSString).utf8String,
                let viewSubclass = objc_allocateClassPair(viewClass, viewClassNameUtf8, 0) 
            else {
                return
            }

            if let method = class_getInstanceMethod(UIView.self, #selector(getter: UIView.safeAreaInsets)) {
                let safeAreaInsets: @convention(block) (AnyObject) -> UIEdgeInsets = { _ in
                    return .zero
                }

                class_addMethod(
                    viewSubclass,
                    #selector(getter: UIView.safeAreaInsets),
                    imp_implementationWithBlock(safeAreaInsets),
                    method_getTypeEncoding(method)
                )
            }

            objc_registerClassPair(viewSubclass)
            object_setClass(view, viewSubclass)
        }
    }
}
