Before the public release of iOS 8.2, Apple on Monday already provided its development community with a beta build of iOS 8.3, along with a new version of its Swift programming language with "noteworthy" changes.
The pre-release version of iOS 8.3 is identified as build 12F5027d. Apple has warned developers that devices updated to the iOS 8.3 beta cannot be restored to earlier versions of iOS.
Exactly what changes are included in iOS 8.3 are unknown. But the fact that it's a point-one release would suggest that Apple has added new features, or plans to before the software becomes public.
In addition, developers were also supplied with Xcode 6.3 beta with Swift 1.2 on Monday. Apple's release notes state that the Swift update contains a number of "noteworthy" changes.
Accordingly, Xcode 6.3 beta includes a new "Swift Migrator" tool that allows developers to move from Swift 1.1 to Swift 1.2.
The release comes one week after Apple provided a fifth beta of iOS 8.2. The iOS 8.2 beta allows developers to begin building applications for the forthcoming Apple Watch.
