App still appears in Dock despite adding LSUIElement in Info.plist

[pycoder2000]

The app is supposed to run as a menu bar application and not appear in the Dock. To achieve this, I added the following key to my Info.plist file:

<key>LSUIElement</key>
<true/>

However, the app still appears in the Dock when launched.

Steps to Reproduce:

1. Set <key>LSUIElement</key><true/> in the Info.plist file.
2. Build and run the app from Xcode.
3. Observe that the app appears in the Dock.

Expected Behavior:

The app should only appear only as a menu bar item and not show up in the Dock.

---

Actual Behavior:

The app still appears in the Dock when launched.

Additional Information:

• Xcode Version: Version 16.2 (16C5032a)
• macOS Version: Sequoia 15.2

Questions and Requests:

1. Could this behavior be caused by how I’m running the app (e.g., directly from Xcode or certain configurations)?
2. Are there any additional settings I need to modify in the Info.plist file or Xcode project?
3. Has anyone else encountered this issue, and how did you resolve it?
