Swift:ワークスペースの切り替えを監視する

More than 1 year has passed since last update.

導入

macOSでワークスペース(デスクトップ)が切り替わったタイミングで処理を発火できます.

実装

Appdelegate.swift
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {

    func applicationDidFinishLaunching(_ aNotification: Notification) { 
        NSWorkspace.shared.notificationCenter.addObserver(self,
                                                          selector: #selector(changedActiveSpace(_:)),
                                                          name: NSWorkspace.activeSpaceDidChangeNotification,
                                                          object: nil)
    }

    @objc func changedActiveSpace(_ notification: NSNotification) {
        Swift.print("切り替わった")
    }

}

NSWorkspace.activeSpaceDidChangeNotificationを使えばいいだけ
