I created a sticker pack with no code. I'm able to export to a developer .ipa file. When I try and upload using Application Loader I get an error:
"Your app contains non-public API usage..."
"The app contains or inherits from non public classes in Payload/***/Plugins/StickerPackExtension.appex/StickerPackExtension:_MSStickerPackCollectionViewDataSource"
I can't figure this out because I haven't added any frameworks or any code, its just images. Is this due to the fact that its a development build? Or are we not able to upload yet from sticker builds from XCode 8 beta 6?
