## What it is
Locksmith is a protocol-oriented Swift library for interacting with the iOS, macOS, watchOS, and tvOS keychain. It provides a simple API for saving, loading, updating, and deleting secure data with strongly typed results.

## Use cases
- store passwords securely in the iOS keychain
- save user credentials on macOS
- read and write keychain items in Swift
- add secure storage to my Swift types via protocols
- delete keychain entries in an iOS app
- manage keychain metadata with strongly typed results

## When to choose
- you need keychain access across iOS, macOS, watchOS, and tvOS
- you prefer a protocol-oriented, Swift-native API over raw Security framework calls
- you want typed access to keychain metadata

## When to avoid
- you need a cross-platform (non-Apple) secure storage solution
- your project targets Swift versions older than 4 without using the legacy branch
- the library appears to be in maintenance mode and you need actively developed features

## Facets
