Apple has released Xcode 6.3 beta to developers including a noteworthy update to the Swift language, incrementing the version to 1.2
The language update includes compiler improvements and new language features such as incremental builds, faster executables both for debug and release builds, better compiler diagnostics and elimination of compiler crashes.
New language features included are improved interaction between Swift and Objective-C and refinements to ensure safe and predictable behavior.
Since the 1.2 release includes some source-incompatible changes compared to previous versions, Xcode 6.3 includes a migrator to help automate the conversion process.
Xcode 6.3 can be used with Xcode’s Continuous Integration service on OS X Server 4.x and Git Source Code management in OS X Server.
More details of Swift 1.2 can be found in the Swift Blog and the full details in the release notes (requires developer account logon).
Maybe the language is now sufficiently mature to build a Swift viewer for OpenSim!
