Xcode 14.3版本運行項目報錯
ld: file not found: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphoneos.a
clang: error: linker command failed with exit code 1 (use -v to see invocation)
因為系統(tǒng)已經內置有ARC相關的庫尿瞭，所以沒必要再額外鏈接，至少Xcode 14支持的最低部署目標iOS 11及以上版本的系統(tǒng)肯定是沒問題的。如果應用部署目標不低于iOS 11還出現(xiàn)問題祟同，那么應該是第三方庫的部署目標有問題腰埂。

在Xcode升級到Xcode14以后叁征，大家都發(fā)現(xiàn)系統(tǒng)的支持版本升級到了11.0全闷，那么想要調試11.0之前的系統(tǒng)該怎么辦呢漂问？
下邊給大家介紹Xcode14調試11.0之前的系統(tǒng)的方法：
1.首先在Xcode14之前的版本下蔼水，應用程序-xcode 顯示包內容 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport 震糖，把程序中的低于11.0的文件夾拷貝到Xcode14的相應目錄下。
2.在Xcode14下趴腋，應用程序-xcode 顯示包內容 修改以下文件,記得修改前備份,防止改錯無法還原.

添加 8.0-10.3 的版本 到以下節(jié)點中
SupportedTargets - iphoneos - ValidDeploymentTargets
DefaultProperties - DEPLOYMENT_TARGET_SUGGESTED_VALUES
如果沒有包含吊说，請把這個plist文件拷貝到桌面手動添加。添加完成后再粘貼到原來的位置优炬。重啟Xcode即可颁井。
3.MinimumDeploymentTarget 改為8.0
配置文件拖出來到桌面 修改,完了覆蓋進去
