Firebase crash report dump_syms is not permitted in iTunes connect upload

[Thein Tun]

I am integrating the Firebase SDK into my app without using CocoaPods for Analytics and Crash Report. When I upload app to the app store, I get the following error. Any idea of what I'm doing wrong here?

>ERROR ITMS-90171: "Invalid Bundle Structure - The binary file 'xxxx.app/dump_syms' is not permitted. Your app can’t contain standalone executables or libraries, other than the CFBundleExecutable of supported bundles. Refer to the Bundle Programming Guide at https://developer.apple.com/go/?id=bundle-structure for information on the iOS app bundle structure."
