Xcode 如何解决；flatter.framework:代码对象根本没有签名"；？

我在将iOS版本的Flitter应用程序存档上传到应用商店时遇到了很大的麻烦。我在

flatterbuildios-v

中没有问题&然后从

Runner.xcworkspace

XCode项目创建存档

但当我尝试从XCode Organizer上传到应用商店，或尝试验证应用时，它会显示：

Xcode中的分发日志（最后几行）是：

我正在成功运行相同的内置模拟器和设备。我尝试过通过

flatter clean

、删除

/ios

中的

Pods

目录、删除

Podfile.lock

&以及

Runner.xcworkspace

我当前的
