A Swift framework for parsing, formatting, and validating international phone numbers, inspired by Google's libphonenumber. This original repository is frozen at 4.3.0; active development has moved to the PhoneNumberKit organization.

Use cases

• validate phone numbers entered by users in an iOS app
• format international phone numbers consistently
• parse a phone number string into country code and national number
• normalize phone numbers from contacts to E.164
• detect the default region code from the device
• build a phone number text field with country code picker

When to choose

• you need libphonenumber-style phone number handling in Swift
• you want a lightweight, fast, well-tested Swift phone number library
• you are pinned to the 4.x API and manage metadata updates yourself

When to avoid

• you want current metadata and active maintenance - use PhoneNumberKit/PhoneNumberKit instead
• you need PhoneNumberTextField or the country picker - use PhoneNumberKitUI
• your project is not in the Swift/Apple ecosystem
