Apple has identified and issued a fix for a bug that prevents data from third-party apps from syncing properly with iCloud. The fix has been implemented on the CloudKit backend, a framework that runs iCloud on iOS, macOS and web.
Â
The technology giant did not reveal what the problem was but in a post on its forum said that the errors were akin to "request-throttling that may be affecting a specific user, or the container as a whole". The Cupertino-based company also blamed an "underlying issue" that "caused an elevated number of these error responses to be returned to your CloudKit apps in certain situations".
Â
Apple concluded by saying that the issue was resolved and reached out to developers to confirm if they were still receiving error messages.

App developers had been facing the problem since November, with Apple not acknowledging the bug until now. The bug led to a lot of users seeing the error message, "Request failed with HTTP status code 503,"Â which developers feared would result in a negative perception of their apps in the eyes of consumers.
