关于ios：Firestore安全规则在模拟器中有效，但在应用程序中失败

Firestore security rule works in simulator but fails in app

我对此Cloud Firestore安全规则有疑问：

service cloud.firestore {
match /databases/{database}/documents {
match /stages/{stageId} {
match /collections/{collectionId} {
match /pois/{poiId} {
allow read;
allow write: if request.auth != null ||
request.method =="update" &&
request.resource.data.keys() == ["pm"];
}

}

}
}
}

在代码中，我尝试使用值字典更新作为未经身份验证的用户的现有文档的字段pm。 Firestore日志显示此请求：

此请求因"缺少权限或权限不足"而失败。

当我使用此模拟数据将update转换为stages/dev/collections/ETzbIXBn0Z5FOsCHtHlv/pois/zJELKLTWupuMkYQNb9gl时

1	{"__name__":"/databases/(default)/documents/stages/dev/collections/ETzbIXBn0Z5FOsCHtHlv/pois/zJELKLTWupuMkYQNb9gl","data":{"pm":{"adminArea":"Germany","testArea":"Munich"}}}

模拟器允许更新。

在我的代码(Swift项目/ iOS)中，我在现有文档参考上使用updateData方法。

作为参数，我传递了这个数组：

1	["pm": ["adminArea":"Faro","name":"Rua Primeiro de Dezembro","postalCode":"8200-142","locality":"Albufeira","subLocality":"Albufeira","isoCountryCode":"PT","timezone":"Europe/Lisbon","thoroughfare":"Rua Primeiro de Dezembro","country":"Portugal"]]

知道我在做什么错吗？谢谢！
