【中文标题】在 iOS 上添加 firebase_core 后 Flutter 返回错误【英文标题】：Flutter returning error after adding firebase_core on iOS 【发布时间】：2021-09-09 04:52:29 【问题描述】：

按照google的firebase团队的指示将.plist文件添加到xcode项目并将firebase_core: ^1.3.0添加到pubspec.yaml后，尝试在ios上运行应用程序时返回以下错误：请注意，我在 android 上成功运行该应用程序而没有错误，当我在 pubspec.yaml 中评论 firebase_core depndency 时，iOS 运行完美。

你用的是什么mac机器？？ Macbook Pro 2015 年初 - Big Sur 【参考方案1】：

通过将 podfile 中的第一行更改为 iOS 版本 12 解决
