NavLibSwift 3.1.0

Additions

• Your app can now offer its own commands for users to assign to 3D mouse buttons. Register a list of NavLibCommand actions and categories with registerCommands(_:setID:) and handle button presses in commandHandler. Users find them in the 3Dconnexion settings under "Exported Commands". This only works in apps that aren't sandboxed, because of a bug in 3Dconnexion's navlib framework.

Improvements

• The public API now has documentation comments, which show up in Xcode's Quick Help.
