Update: The problem should now be resolved. Watch apps should upload as normal once again.
Developers are flocking to Apple’s developer forums today as the iTunes Connect submissions process is currently experiencing a glitch which makes it impossible for developers to submit apps that include Apple Watch extensions.
Rather than continuing submission process as normal, the system is incorrectly flagging up misuse of an Apple private framework called SockPuppetGizmo. Naturally, this is causing frustration in the developer community at the moment because it prevents apps from being submitted to the App Store.
Apple has started enforcing a long-ignored rule in its App Store guidelines regarding what kinds of content can appear in app metadata. According to rule 3.6 in the guidelines document:
Apps with App icons, screenshots, and previews that do not adhere to the 4+ age rating will be rejected
This rule has been mostly unenforced since the App Store launched, but according to a new report from Pocket Gamer, some app developers are starting to see their apps rejected for depictions of violence in their screenshots.
