【问题描述】：
我最近购买了带有M1 芯片的新 Mac 书，在构建时遇到了 Flutter 和 Firebase 之间的巨大问题。我会同时列出 Flutter 错误日志和 Xcode 错误日志。
注意：我正在 Flutter 频道 Master
上构建Flutter 错误日志：
Launching lib/main.dart on iPod touch (7th generation) in debug mode...
Xcode build done. 69.1s
Failed to build iOS app
Xcode 构建的错误输出：

objc[30795]: Class AMSupportURLSession is implemented in both ?? (0x1fe91f940) and ?? (0x118940308). One of the two will be used. Which one is undefined.
** BUILD FAILED **

这是主要错误，有很多警告，但我不确定它们是否导致构建失败。

你检查你的证书了吗？如果您运行
flutter build ios --verbose，您是否会收到类似“无法为签名者构建自签名根的链......”的消息？
