I have problem with my ios app ipa package.
Transport program shows me :

ERROR ITMS-90171: “Invalid Bundle Structure - The binary file ‘reqnet.sterowanie.app/reqnet.sterowanie.dSYM/Contents/Resources/DWARF/reqnet.sterowanie’ is not permitted. Your app can’t contain standalone executables or libraries, other than a valid CFBundleExecutable of supported bundles. Refer to the Bundle Programming Guide at Redirect: Bundle Programming Guide - Bundle Structures for information on the iOS app bundle structure.”

Why this package is generated and how to turn off it ?
Best regards
