React Native SwiftUI 'unrecognized selector sent to instance'

$

I'm trying to use a SwiftUI component with my React Native app, which appears to be a little complicated since I haven't found any documentation or tutorials for doing this online. Here are the files I'm using:

CategoryCardView.swift

import UIKitimport SwiftUIstruct CategoryCard: View {  var name: String  var body: some View {      Text(name)  }}@objc(RCTCategoryCardViewManager)class RCTCategoryCardViewManager: RCTViewManager {  override static func requiresMainQueueSetup() -> Bool {    return true  }  @objc var name: String = "Default text"  override func view() -> UIView! {    let swiftUIView = CategoryCard(name: name)    let viewController = UIHostingController(rootView: swiftUIView)    return viewController.view  }}

CategoryCardView.m

#import <React/RCTViewManager.h>@interface RCT_EXTERN_MODULE(RCTCategoryCardViewManager, RCTViewManager)RCT_EXPORT_VIEW_PROPERTY(name, NSString)@end

NativeCategoryCard.tsx (in React Native):

import {requireNativeComponent} from "react-native";import React from "react";const NativeCategoryCard = requireNativeComponent('RCTCategoryCardView');export interface CategoryCardProps{    name: string;}function CategoryCard(props: CategoryCardProps) {    return <NativeCategoryCard        style={[{            height: 100,            width: 100        }]}        {...props}    />}export default CategoryCard;

And then somewhere in my React Native code:

<CategoryCard text='hello' />

My app throws the following error when it tries rendering <CategoryCard>:

Exception thrown while executing UI block: -[_TtGC7SwiftUI14_UIHostingViewV7PalChat12CategoryCard_ setName:]: unrecognized selector sent to instance 0x7fc8718c7830

I don't really understand Swift and SwiftUI thoroughly, especially in terms of integrating it with React Native, so I apologise if I'm making an obvious mistake.
