无法从反应原生iOS应用程序的数据库中检索Firestore文档

我正在使用firestore来检索/存储反应原生应用程序的一些消息 . 一切都在Android上按预期工作，但在iOS上我只能看到缓存的消息 . 该应用程序配置没有cocoapods，任何本机库已手动链接 .

我的想法是，我缺少某种参数来允许请求对firebase域的请求，或者我的firebase配置可能不正确 . 我的plist文件和调用firestore的代码都列在下面 . 我缺少任何选项/属性吗？

下面是从firestore集合中检索数据的代码

firebase.firestore().collection('messages')
      .orderBy('timestamp', 'asc')
      .limit(50)
      .onSnapshot(snapshot => {
          console.log('On Fetch...')

        let newState = {
          messages: []
        };

        snapshot.forEach(function(doc) {
          newState.messages.push({
            id: doc.id,
            message: doc.data().message
          });
        });
      });

以下是我的GoogleService-Info.plist文件
