How to Programmatically Retrieve Running Application Bundles in OS X

In OS X, fetching a comprehensive list of actively running application bundles presents a considerable challenge. Unlike querying running processes, which can be accomplished using sysctl() and KERN_PROC_ALL, uncovering their corresponding application bundles remains elusive. This emerges as a significant roadblock for applications seeking to log usage time or implement parental control features.

A potentially viable approach involves utilizing the Activity Monitor, which designates certain processes with icons and provides insights into their application origins. However, replicating this behavior programmatically becomes a language-specific endeavor.

Solution Using Swift and Cocoa APIs

Within the realm of Swift and Cocoa APIs, a solution has emerged:

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

// Acquire all running applications
let workspace = NSWorkspace.shared
let applications = workspace.runningApplications

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

Here, the "app" object represents an NSApplication instance. By leveraging this object, the application's bundle identifier, the sought-after information, can be obtained effortlessly.
