Apple has started seeding third previews of OS X Yosemite and iOS 8 to developers. The former is listed as build 14A283o, and can be downloaded via the Mac App Store or the Mac Dev Center. iOS 8 beta 3 is identified as build 12A4318c, and available either as an over-the-air update or through the iOS Dev Center. To go with it, Apple is pushing out new betas of Find my iPhone and Find My Friends.
Both releases are arriving three weeks after the last round of betas. Release notes don’t mention any specific changes, but those are likely to be discovered in the next few days. On Friday, Apple warned developers that it would do a wipe of CloudKit databases today, something presumably connected to the new betas.
