我是一个编码新手。在SwiftUIKit中编写代码时，我很难将文档上传到Firestore数据库。程序给我的警告消息为

• '权限被拒绝：缺少权限或权限不足。'/failed：权限缺失或不足*

我已经检查了消息，并尝试了所有的解决方案，但仍然无法修复它。我已经改变了规则在Firebase很多次，最后一个是这样的;

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write: if request.auth != null
    
    }
  }
}

这是我的代码，应用程序应该运行/上传数据到数据库，但它没有。我希望你能帮助我...谢谢你：）
