## What it is
A Swift framework implementing the OAuth2 protocol for macOS, iOS, and tvOS apps. It supports all OAuth2 flows including code grant, with keychain integration and configurable client settings.

## Use cases
- add oauth2 login to an ios app
- authenticate a macos app against github
- implement authorization code grant flow in swift
- handle oauth token storage in the keychain
- connect a tvos app to an oauth2 provider
- use universal links as oauth redirect uris

## When to choose
- building a native Apple-platform app that needs OAuth2 authentication
- you want keychain-backed token storage out of the box
- you need support for multiple OAuth2 grant types in Swift

## When to avoid
- you need OAuth for a non-Apple platform
- you need OIDC features beyond plain OAuth2
- your project targets Swift versions older than 5
