Ios 更改Xcode 11后找不到架构x86_64的符号

我将Xcode更新为11

我发现了这个链接器错误

对于模拟器或设备，结果相同

也许这与谷歌图书馆有关

代码由

flatter

有人帮忙吗

我从谷歌下载了GoogleMobileAdsdkios-7.64.0.zip

并手动将

GoogleMobileAds.framework

复制到ios/Frameworks

然后，目标

Runner

->

构建阶段

->

将二进制文件与库链接

->在

GoogleMobileAds.framwork

文件夹下添加（+）

GoogleMobileAds

文件

我想根本原因是Cocoapod不能正常工作

---

所以我手动添加了框架，然后解决了。

在这种类型的错误中，最适合我的解决方案是删除外部库，然后重新安装。
