How to completely remove bundle id in iOS development?

How can I reuse the bundle ID I have created for the app ID? I even delete the associated app ID but the bundle ID still unavailable.Does it to say bundle ID couldn't be removed completely once created?

The bundle id can't be reused as exact. For example com.abc.xxx can be used only once. If you had created this app Id from one account, you can't create the same app Id from the other account. However, you will still be able to create a new one as com.abc.xxx1 like or so. There should be atleast 1 character difference in the app Id's

If you want to delete an app ID, follow these steps:

1. Open https://developer.apple.com and enter using your credentials.
2. Click on Identifiers under the Certificates, Identifiers & Profiles section.
3. Now click on the App ID you want to Delete.
4. Click on Remove next to Edit your App ID Configuration.
5. Again click on Remove in the confirmation message that opens.
