Apple rolls out fix for bug that could break iCloud sync

Apple has identified and rolled out a bug fix that intermittently prevented third-party apps from syncing in iCloud (via 9to5Mac). In a response to a developer on Apple’s community forum, Apple says it has “investigated this issue on the CloudKit backend and has implemented a fix.”

The company still has not specified exactly what went wrong – it said the errors “resemble request regulation that could affect a specific user or container as a whole,” and blatantly accused “an underlying problem” of causing the widespread synchronization problems.

As 9to5Mac reports, developers have been dealing with this issue since November, which has not been publicly acknowledged by Apple until now. Developers note that their users have received a “Query failed with HTTP status code 503”, which largely results in a bad appearance for developers (without consequence for Apple). Back then 9to5Mac also said that some developers were contacted individually by Apple and told that the problem had to do with CloudKit.

It’s unclear why it took so long for Apple to respond, or why it does not solve the problem on a larger platform. When The edge reached out to Apple, we were referred to the company post on the developer forum instead of an official statement.

Aside from the app sync issue, Apple experienced some outages related to its other iCloud services, including iCloud Photos, iCloud Mail, and iCloud Backup, but as seen on Apple’s System Status page and DownDector’s chart, it appears that the issue for it most are solved.
