一、Xcode14.3的问题

添加了fluttertoast库后，执行flutter run后会报错如下

flutter run
Launching lib/main.dart on iPhone 14 Pro in debug mode...
Running pod install...                                           2,039ms
Running Xcode build...                                                  
Xcode build done.                                           12.1s
Failed to build iOS app
Error (Xcode): File not found:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphonesimulator.a


Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation)


Could not build the application for the simulator.
Error launching application on iPhone 14 Pro.

解决办法：
1、下载一个旧的xcode包。https://download.developer.apple.com/Developer_Tools/Xcode_14.2/Xcode_14.2.xip
2、将旧xcode中的arc/libarclite_iphonesimulator.a文件夹整体复制到新的xcode里。
