Xcrun PackageApplication, failed unable to copy application

Я создал простое приложение в Xcode. Настроил инициализацию для конфигурации Debug и Release. Выполняю в терминале:

xcodebuild -target signtest -configuration Debug -sdk iphoneos clean build

И оно собирается правильно. Теперь я пытаюсь создать ipa файл с помощью этой команды:

/usr/bin/xcrun -sdk iphoneos PackageApplication -v /Users/admin/Desktop/signtest/signtest/build/Debug-iphoneos/signtest.app/  -o /Users/admin/Desktop/binaries/signtest.ipa

И получаю эту ошибку:

Что здесь не так?
