Build finished with errors/Executable Not Found

Xcode error:
Build finished with errors/Executable Not Found

• The expression is:
  There are Errors errors during compilation but the compilation is passed.When installing, it prompts that the executable file is not found.

• Reason:
  Some files may not be deleted cleanly, such as manually deleting from Finder, or selecting remove refrence, resulting in file indexes remaining in Compile Sources

• Solution:
  Build Phases-> Compile Resources, delete the problematic files (if there are too many files, you can select the Filter input box in the upper right corner to directly locate the problematic files)
