我正在我的应用程序中实现Firebase phoneNumber验证.然后在我的应用程序中生成错误：

If app delegate swizzling is disabled, remote notifications received by UIApplicationDelegate need to be forwarded to FIRAuth\’s canHandleNotificaton: method.

最佳答案 您可能错过了在AppDelegate中添加此方法

func application(_ application: UIApplication,
                 didReceiveRemoteNotification notification: [AnyHashable : Any],
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    if Auth.auth().canHandleNotification(notification) {
        completionHandler(.noData)
        return
    }
    // This notification is not auth related, developer should handle it.
    handleNotification(notification)
}
