Apple Once Again Erases All CloudKit Data For iOS 8 And OS X Yosemite Betas

Apple’s introduction of the various CloudKit APIs within iOS 8 and OS 10.10 Yosemite at this year’s Worldwide Developer Conference was greeted with much glee and excitement from attending developers. The creation of CloudKit will ultimately afford developers with the ability to focus on creating impressive and immersive client-side experiences rather than having to deal with the issues that come attached with server-side cloud storage code. As the APIs are being developed and ironed out it seems that testers will need to put up with some bumps in the road with Apple once again notifying developers that all CloudKit data will once again be wiped at some point today.

Early adopter developers who have chosen to get down and dirty with the new CloudKit APIs will surely appreciate that the wiping of any stored data is ultimately part of the roadmap to launch. Today’s deletion of all public CloudKit databases will be the second such occurrence in the time that has followed since the introduction of the technology at WWDC. As part of the process of upgrading internal storage servers to work alongside the launch of the latest iOS 8 and Yosemite betas, Apple performed a similar wipe of CloudKit public data back on July 7th.

In an attempt to make the process as seamless and transparent as possible, the Cupertino-based company has taken the additional step of emailing all registered developers with more in-depth information regarding the purge. Yesterday’s iOS 8 beta 4 release and Yosemite’s 4th Developer Preview came attached with release notes informing of the data wipe. The follow up email sent out to all iOS and OS X developers goes a little further by clarifying why the purge is necessary as well as outline specific data that won’t be part of the deletion:


As per Apple’s instructions, if you’re one of the developers tinkering with the new APIs, then make sure you create a copy of any important data that is stored within a public CloudKit database before it’s gone forever.
