While we highly recommend taking advantage of the latest version of Swift which provides a Web interface, Isode continues to offer Swift 4.0

Swift 4.0 is an open source, desktop version of our Swift XMPP Chat client. Whilst it is not likely to receive any further updates, there are support packages available for purchase should you require custom support and bug fixes for your deployment.

Key features of Swift 4.0

  • Security Labels: Swift supports the security labelling of messages, ensuring that in both MUC rooms and 1:1 chats, messages can only be delivered to those with the security clearance required to view them (requires support from an appropriate server).
  • Trellis Mode: Enables the user to view several MUC rooms and 1:1 chats at the same time, instead of on a tabbed interface.
  • Keyword/Phrase Highlighting: Easily create highlight rules for key words or phrases across multiple conversations, include the ability to highlight words or phrases only when used by specific individuals.
  • Message Delivery Receipts: Swift can request and display an acknowledgement from the target user's client (1:1 chat).

Swift supports Strong Authentication using certificates and smart-cards as well as password-based SASL authentication mechanisms.

Commercial Support Packages

The open source version of Swift is written with Swiften and licensed under the GNU General Public License. Swiften is offered under both commercial licensing, from Isode, and under the GNU General Public License.

Development has been supported by Isode with the contribution of considerable engineering effort. The open-source version of Swift will always be a free client, however Isode does offer commercial support for large installations and mission-critical environments as well as commercial licenses and commercial support contracts for Swiften.

Swift 4.0 is available for Windows, Mac OS X (10.9+) as well as AppImage for 64-bit Linux systems. Swift 4.0 can be downloaded from the open source Swift website, along with the source code of Swift 4.0 and Swiften.
