✅ It's not a serious problem but very annoying after updating to Xcode 8 and macOS Sierra. A lot of "is missing from working copy" warnings have shown up like the following one. I know these files were deleted from my project several months ago. Does anyone know how to get rid of them?warning: Missing file: /Users/me/Desktop/MyAppFolder1/MyAppFolder2/MyAppxcode/MyApp/Textrtfd_iPhonePlus/8_10plus.rtfd/TXT.rtf is missing from working copy
