An instance of NSSetCommand sets one or more attributes or relationships to one or more values; for example, it may set the (x, y) coordinates for a window’s position or set the name of a document.


NSSetCommand is part of Cocoa’s built-in scripting support. It works automatically to support the set command through key-value coding. Most applications don’t need to subclass NSSetCommand or call its methods.

NSSetCommand uses available scripting class descriptions to determine whether it should set a value for an attribute (or property), or set a value for all elements (to-many objects). For the latter, it invokes replaceValue(at:inPropertyWithKey:withValue:); for the former, it invokes setValue(_:forKey:) (or, if the receiver overrides takeValue:forKey:, it invokes that method, to support backward binary compatibility.)

For information on working with set commands, see Getting and Setting Properties and Elements in Cocoa Scripting Guide.


Working with specifiers

var keySpecifier: NSScriptObjectSpecifier

Returns a specifier that identifies the attribute or relationship that is to be set for the receiver of the set AppleScript command.

func setReceiversSpecifier(NSScriptObjectSpecifier?)

Sets the receiver’s object specifier.
