After uploading to Xcode 9.2 I copied an update and I am now getting ITMS-90503. The app has an iOS component, a sticker component, a watch component, and an ext for a widget. Any thoughts on how to resolve. I have tried the arm64 suggestions online with still continuing to get this error.
ITSM-90503 - Existing App Arm64 error
Found the issue, incase anyone else is having this issue. After about 12 hours of going through to figure this out I found out I had to add armv7 and armv7s to the sticker pack and armv7k to the watch. All others had to have just arm64 and it submitted without any issue. Hope this helps someone else.
