在Flutter开发项目中APP想实现新功能，所以需要接入新的第三方插件，但是有些第三个的Dart SDK版本要求很高，所以不得不升级Flutter SDK。于是索性把FLutter SDK升级到最新的3.X.X版本，然后遇到了iOS运行时找不到Swift动态库的问题：

通过百度找到了这遍dyld:Library not loaded: @rpath/libswiftCore.dylib文章，但不能解决。
后面又找到了下面的方法，成功解决这个问题。
在项目的TARGETS下Runner的Build Settings->Linking->Runpath Search Paths配置添加/usr/bin/swift和/usr/lib/swift，如下图：

然后成功运行。
