Been having a really bad problem lately where I can’t upload my apps to the app store for testing builds, and sending them to teammates over TestFlight.
When I try to upload to the App Store via Xcode or the Application Uploader, it gets to the very end of the upload process then throws a whole bunch of errors: ERROR ITMS-90328 “Your package contains a file ‘appname.app/Data/Managed/Icon’ with a name that contains invalid characters. Avoid using control characters in the file names.”
The files in question are just empty hidden files named “Icon”, that don’t contain any data and as far as I can tell don’t have any invalid characters. Weirdly, I’ve tried deleting them altogether and the exact same error occurs. The error gets thrown multiple times too, with the filepath changing (instead of Data/Managed/Icon itll be Data/Icon, Data/Managed/mono/2.0/Icon, etc)
Any help here would be great! Stopping those Icon files from spawning, preventing the error, anything to let me upload to the app store. I’m using the latest Unity on the latest OS X, publishing for iOS. I’ve also replaced all the default Unity icons and splash screen with custom art.
