The Execute a Swift Script action executes a specified Swift script, either from a file or text.

The results of the script can be:

• Ignored.
• Displayed in a floating window.
• Displayed briefly in a Notification.
• Typed in to the current selection.
• Pasted in to the current selection.
• Saved to a variable.
• Saved to the system or a Named Clipboard.
• Asynchronously ignored — the action runs while the macro continues on.

Swift scripts can access variables by using environment variables, for example:

import Foundation
println( NSProcessInfo.processInfo().environment["KMVAR_Variable_Name"]! )
