Contacts

The Contacts framework provides Swift and Objective-C APIs to access the user's contact information. Because most apps read contact information without making any changes, this framework is optimized for thread-safe, read-only usage.

Stores and organizes contact information, including names, phone numbers, emails, addresses, and more. It works with services like iCloud, Exchange, and Google to keep contacts up-to-date across all devices. It also adds photographs to contacts for quick recognition.
