This component is intended as a replacement for SS_PrefsController by Matt Legend Gemmell and Selectable Toolbar by Brandon Walkin. It is designed to use NSViewController subclasses for preference panes.

You can find a Demo project at MASPreferencesDemo.

##Swift Edge case When using Swift you need to override the identifier from MASPreferencesViewController the following to be compatible with the mutable identifier String? in NSViewController

override var identifier: String? { get {return "general"} set { super.identifier = newValue} }
