Ted Kremenek is a member of the Swift Core Team and manages the Languages and Runtimes group at Apple.
We are very pleased to announce Developer Preview 1 of Swift 3.0!
As described in the Swift 3.0 Release Process, developer previews (i.e., “seeds” or
“betas”) provide qualified builds of Swift 3 that are more stable than just
grabbing the latest snapshot of master (i.e., tip-of-trunk development).
Developer previews capture Swift 3 as a work-in-progress and should not
be considered the final version of Swift 3 unless otherwise stated.

Migrating to Swift 3
Swift 3 is a source-breaking release over Swift 2.2.1. It contains many syntactic refinements and improvements,
but also a huge number of changes for how Objective-C APIs import into Swift due to SE-0005.
Please consult the migration guide for guidance and tips
for migrating to Swift 3.
