运行程序报错

ld: file not found: ~/Library/Developer/Xcode/DerivedData/xxx-fxhqtzymbwegttddoznsqpakmlvp/Build/Products/Debug-iphonesimulator/xxx.app/xxx

clang: error: linker command failed with exit code 1 (use -v to see invocation)

clean 项目后  删除DerivedData后 重启Xcode不起作用

2种解决办法

1）左击工程文件：

选择Edit Scheme

把红色圈住的去掉就ok了

2）Proj->BuildingSetting-搜应用名 ->Product Name更改为和 Executable file一致（proj->info->Executable file）
