Apple Warns Developers of Server-Side Data Wipe for iOS 8 and OS X Yosemite on July 7th

Apple has sent an email to developers warning them of a server-side data wipe for iOS 8 and OS X Yosemite on July 7th.

-----
Dear Developer,


We will be performing a server-side data wipe on all CloudKit public and private databases for iOS 8 beta and OS X Yosemite Developer Preview users on July 7, 2014. The following iCloud features will be affected: iCloud Drive, iCloud Photo Library, and Mail Drop.

Photos and videos stored in iCloud Photo Library will remain on their original iOS 8 devices and will upload to iCloud Photo Library again automatically. iCloud Drive can be re-enabled from Set up Assistant after upgrade. If you choose to store your documents in iCloud Drive, your Documents & Data will automatically be copied to iCloud Drive. iCloud Drive will not update across earlier seeds or operating systems. Attachments sent through Mail Drop will expire and need to be resent after you upgrade.

If you have any questions, visit the Apple Developer Forums.

Best regards,
Apple Developer Technical Support
