在Flutter開發(fā)項(xiàng)目中APP想實(shí)現(xiàn)新功能，所以需要接入新的第三方插件，但是有些第三個(gè)的Dart SDK版本要求很高矗愧，所以不得不升級(jí)Flutter SDK梯醒。于是索性把FLutter SDK升級(jí)到最新的3.X.X版本宽堆，然后遇到了iOS運(yùn)行時(shí)找不到Swift動(dòng)態(tài)庫的問題：

通過百度找到了這遍dyld:Library not loaded: @rpath/libswiftCore.dylib文章，但不能解決冤馏。
后面又找到了下面的方法日麸，成功解決這個(gè)問題。
在項(xiàng)目的TARGETS下Runner的Build Settings->Linking->Runpath Search Paths配置添加/usr/bin/swift和/usr/lib/swift逮光，如下圖：

然后成功運(yùn)行代箭。
