iOS Bundle ID Formatting Rules

Reverse-DNS Format

Apple mandates a reverse domain name structure (e.g., `com.domain.appname`) to guarantee uniqueness across the App Store ecosystem.

Character Restrictions

Bundle IDs may contain alphanumeric characters (`A-Z`, `a-z`, `0-9`), hyphens (`-`), and periods (`.`). Spaces and special symbols are prohibited.

App Extensions

Companion app extensions (like widgets or share extensions) must use the main app's bundle ID as a prefix (e.g., `com.domain.appname.widget`).

Frequently Asked Questions (FAQ)

While you can easily update the bundle ID in your local Xcode project settings, changing it after publishing to App Store Connect requires creating an entirely new App ID and record.

An explicit App ID matches a exact bundle ID string and is required to leverage specific Apple capabilities like Push Notifications, Associated Domains, and In-App Purchases.
