这有点奇怪。
我认为这与XCode 12有关，但是我同时进行了一些项目更改，也许就是这样。看来我可以将项目有意义地成功部署到运行ios 13或ios 14的设备上，项目运行正常，但是当我尝试部署到模拟器时，它无法将某些内容复制到目标中。我已经在各个论坛中查看了许多相关问题，但还没有看到专门解决的问题。

总是导致：
error: Build input file cannot be found: '/Users/seanl/Library/Developer/Xcode/DerivedData/PROJNAME-dmjlgigvatannqerrubxabptwsnp/Build/Products/Debug-iphonesimulator/APPNAME.app/APPNAME' (in target 'APPNAME' from project 'PROJNAME')
正如我所说，这只是在模拟器上构建的，设备工作正常。有趣的一点是它没有使用swift，但是有一个copySwiftLibs调用，尽管这也许是一个通用的库副本。
我已经在网上搜寻想法，任何想法吗？
谢谢。
