Apple fixes iOS 9 app slicing bug, releases full text transcripts of WWDC 2015

Apple on Monday announced it has fixed an iCloud bug that prevented the release of iOS 9 App Thinning features, and released searchable text transcripts of WWDC 2015's keynote and developer sessions.

The App Thinning fix comes less than two weeks after Apple initially announced it was delaying rollout of the space-saving feature due to an issue related to iCloud backups.

Touted as a key iOS 9 feature, App Thinning is a blanket term for a trio of technologies —app slicing, On Demand Resources and Bitcode —designed to cut down on app install size. By implementing these features, Apple is able to keep software bloat down for users with lower capacity devices.

The recent iCloud bug was affecting app slicing, which pares down universal app downloads to only those assets necessary for running on a particular device. For example, an iPhone 5s does not require the same graphical assets as an iPad Air. As detailed by Apple, an iCloud issue was prohibiting app backups from restoring to other device types, for example from an iPhone 5s to iPhone 6s.

With the fix in place, device-specific app versions will be delivered to customers when downloaded on devices running iOS 9.0.2 or later.

In a separate announcement, Apple revealed full text transcripts of this year's WWDC session videos, including the keynote at which iOS 9 and OS X 10.11 El Capitan were unveiled. Developers can search for keywords, session topics and more on Apple's WWDC videos webpage.
