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 get (but not set) Keyboard Maestro Variables by using environment variables, for example:

Swift 2 (Xcode 7 and 8)

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

Swift 3 (currently beta, Xcode 8)

import Foundation
print(ProcessInfo.processInfo.environment["KMVAR_Variable_Name"]!)
