Error ITMS-90206 Invalid bundle contains disallowed file 'Frameworks'
I faced the same problem while trying to upload from Xcode 9.3 This happened because I added 'use_frameworks' in my OneSignal NotificationServiceExtension
The value Always Embed Swift Standard Libraries found in Build Settings should be set to Yes only for you main Projects and not for your custom frameworks or extensions.
I solved the problem
Firstly, set into Build Settings
For main project (here XXX) :
Embedded Content Contains Swift Code
to YESCustom Framework (SharedXXX) :
Embedded Content Contains Swift Code
toNO
Custom Framework (SharedXXX) :
Runpath Search Path
=@executable_path/../../Frameworks
This helped me solving that issue
