要在SwiftUI应用中实现Apple ID授权登录，您可以按照以下步骤操作：

1. 在Apple开发者账号中为您的应用程序配置Sign in with Apple认证信息。
2. 在Xcode中创建一个SwiftUI项目。
3. 导入AuthenticationServices框架。
4. 创建一个View来显示Apple ID登录按钮，并处理登录成功或失败的情况。

下面是一个简单的示例代码，演示如何在SwiftUI应用中实现Apple ID授权登录：

import SwiftUI
import AuthenticationServicesstruct ContentView: View {var body: some View {VStack {Text("Welcome to MyApp")SignInWithAppleButton().frame(width: 200, height: 50).onTapGesture {performSignInWithApple()}}}func performSignInWithApple() {let request = ASAuthorizationAppleIDProvider().createRequest()request.requestedScopes = [.fullName, .email]let authorizationController = ASAuthorizationController(authorizationRequests: [request])authorizationController.delegate = selfauthorizationController.presentationContextProvider = selfauthorizationController.performRequests()}
}extension ContentView: ASAuthorizationControllerDelegate {func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {// 处理成功登录的情况if let appleIDCredential = authorization.credential as? ASAuthorizationAppleIDCredential {// 使用appleIDCredential.user和appleIDCredential.email等信息进行后续操作}}func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) {// 处理登录失败的情况print("Error: \(error.localizedDescription)")}
}extension ContentView: ASAuthorizationControllerPresentationContextProviding {func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {return UIApplication.shared.windows.first!}
}struct ContentView_Previews: PreviewProvider {static var previews: some View {ContentView()}
}
