The NSAppleScriptMBS class provides the ability to load, compile, and execute scripts.

Example

Var source as string = "tell Application ""iTunes"" to pause"
Var n as new NSAppleScriptMBS(source)
call n.execute

Your application may need the NSAppleEventsUsageDescription entry in info.plist to do any AppleScript usage:
https://developer.apple.com/documentation/bundleresources/information_property_list/nsappleeventsusagedescription

If you use hardened runtime, which you need for notarization, you may need the entitlement for Apple Events, too:
https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_automation_apple-events

Important: You should access NSAppleScriptMBS only from the main thread.

This class provides applications with the ability to

load a script from a URL or from a text string
compile or execute a script or an individual Apple event
obtain an NSAppleEventDescriptorMBS containing the reply from an executed script or event
obtain an attributed string for a compiled script, suitable for display in a script editor
obtain various kinds of information about any errors that may occur

Important: NSAppleScriptMBS provides the execute method so that you can send an Apple event to invoke a handler in a script. (In an AppleScript script, a handler is the equivalent of a function.) However, you cannot use this method to send Apple events to other applications.

When you create an instance of NSAppleScriptMBS object, you can use a URL or a folderitem to specify a script that can be in either text or compiled form, or you can supply the script as a string. Should an error occur when compiling or executing the script, several of the methods return a dictionary containing error information. The keys for obtaining error information, such as NSAppleScriptErrorMessage, are described in the Constants section.
