ITMS-90338: Non-public API usage - The app contains one or more corrupted binaries. Rebuild the app and resubmit.. If method names in your source code match the private Apple APIs listed above, altering your method names will help prevent this app from being flagged in future submissions. In addition, note that one or more of the above APIs may be located in a static library that was included with your app. If so, they must be removed. For further information, visit the Technical Support Information at http://developer.apple.com/support/technical/ I have a similar problem with Flutter. When I removed the frameworks in the project and set 'enable bitcode', the problem was solved. However, these frameworks are important to the project, I can't delete them just because of this apple problem. Is there a way to solve the problem with 'disable bitcode' still set?

This is exactly my problem. It seems that Apple has not fully resolved it yet. Have they contacted you yet?

Okay I figured out how to solve this for cross-platform apps. In Target -> Build Settings -> Other Linker Flags, remove -interposable. Rebuild app
