How to Programmatically Retrieve a List of Running Applications in OS X?

Detecting Running Applications in OS X Using System Calls

Question:

How can I programmatically retrieve a list of all currently running application bundles in OS X, including those displayed in the Dock or Activity Monitor?

Answer:

To obtain the desired information, utilize Cocoa APIs. The following Swift code sample provides an example:

<code class="swift">import Foundation
import AppKit

// Gather running applications
let workspace = NSWorkspace.shared
let applications = workspace.runningApplications

// Inspect each application
for app in applications {
    print(app)
}</code>

The app variable in this code represents an NSApplication object, which provides access to the bundle identifier, providing the information you seek.
