Tengo un problema grave en Xcode 8 en macOS Sierra. cuando intento compilar mi aplicación, aparece el siguiente problema.

CodeSign /Users/me/Library/Developer/Xcode/DerivedData/MyApp-gnoiiwnelmxzdidnijaswisrwdqe/Build/Products/Debug-iphonesimulator/MyApp.app
cd /Users/me/Desktop/MyAppFolder1/MyAppFolder2/MyAppxcode
export CODESIGN_ALLOCATE=/Users/me/Downloads/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate
export PATH="/Users/me/Downloads/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin:/Users/me/Downloads/Xcode.app/Contents/Developer/usr/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"

Signing Identity:     "-"

/usr/bin/codesign --force --sign - --timestamp=none /Users/me/Library/Developer/Xcode/DerivedData/MyApp-gnoiiwnelmxzdidnijaswisrwdqe/Build/Products/Debug-iphonesimulator/MyApp.app

/Users/me/Library/Developer/Xcode/DerivedData/MyApp-gnoiiwnelmxzdidnijaswisrwdqe/Build/Products/Debug-iphonesimulator/MyApp.app: resource fork, Finder information, or similar detritus not allowed
Command /usr/bin/codesign failed with exit code 1

entonces lo hicehttps://forums.developer.apple.com/thread/48905 en la terminal como la siguiente y funcionó. pero una vez que limpio, el problema vuelve.

cd /Users/me/Library/Developer/Xcode/DerivedData/MyApp-gnoiiwnelmxzdidnijaswisrwdqe/Build/Products/Debug-iphonesimulator/MyApp

ls -al@ *

xattr -c *

y esta solución no funciona para el archivo con el siguiente problema. ¿hay alguna solución para ello?
