How to find the bundle ID of an iOS application

If you’re an iOS developer looking to modify an existing app or create a new one, knowing the bundle ID is crucial. The bundle ID is a unique identifier assigned to your app when it’s submitted to the App Store. It allows you to manage and distribute your app across different platforms and devices.

What is a Bundle ID?

A bundle ID is a unique identifier assigned to each iOS app when it’s submitted to the App Store. It consists of two parts: the team identifier and the app name or identifier. The team identifier is a unique identifier for your development team, while the app name or identifier is a unique identifier for your specific app. The bundle ID is used to identify your app in the App Store and in the iTunes Connect portal.

Finding the Bundle ID of an Existing App

If you have an existing iOS app that you want to modify, there are two ways to find its bundle ID:

Using iTunes Connect

iTunes Connect is a web-based platform where you can manage your apps, including finding their bundle IDs. Follow these steps to find the bundle ID of your app using iTunes Connect:

1. Log in to your iTunes Connect account
2. Click on the “My Apps” tab
3. Find the app you want to modify and click on its name
4. Scroll down to the “App Information” section
5. Look for the “Bundle ID” field, which should display your app’s unique identifier

Using Xcode

Xcode is a development environment used to build iOS apps. If you have the source code of your app, you can use Xcode to find its bundle ID. Follow these steps:

7. Open Xcode and create a new project
8. In the “Navigator” window, click on your project in the left-hand sidebar
9. Click on the “.xcworkspace” file in the top-level directory of your project
10. In the “File Inspector” window, look for the “Identifiers” tab
11. Look for the “Bundle ID” field, which should display your app’s unique identifier

Creating a New App with a Custom Bundle ID

If you want to create a new iOS app with a custom bundle ID, you need to follow these steps:

1. Create a new Xcode project

   Open Xcode and create a new project by selecting “File” > “New” > “Project”. Choose the “Single View App” template and click “Next”. Enter your project details and click “Create”.

   Set the bundle ID in Info.plist

   The bundle ID is stored in the Info.plist file of your app. To set a custom bundle ID, follow these steps:

   2. Open Xcode and open your project
   3. In the “Navigator” window, click on your project in the left-hand sidebar
   4. Click on the “.xcworkspace” file in the top-level directory of your project
   5. Right-click on the Info.plist file in the “File Explorer” and select “Show in Finder”
   6. Open the Info.plist file with a text editor
   7. Scroll down to the bottom of the file and look for the “CFBundleIdentifier” line
   8. Replace the default bundle ID with your custom bundle ID
   9. Save the changes to the Info.plist file

   Distribute your app

   Once you’ve set the bundle ID in Info.plist, you can distribute your app to the App Store or other platforms. When distributing your app, make sure to use your custom bundle ID to avoid any conflicts with other apps with the same name.
