## What it is
Resolver is an ultralight dependency injection / service locator framework for Swift on iOS, supporting multiple injection strategies and property wrappers. It is officially deprecated in favor of the author's successor library, Factory.

## Use cases
- dependency injection in swift ios apps
- service locator pattern in swift
- inject dependencies into viewcontrollers with property wrappers
- manage service scopes like cached or graph in swift
- resolve protocols to implementations at runtime
- pass arguments when resolving services in swift

## When to choose
- maintaining an existing codebase already built on Resolver
- you need a tiny single-file DI framework for a legacy Swift project

## When to avoid
- starting a new Swift project - use Factory instead
- you need compile-time safe dependency injection
- the project is actively developed and needs long-term support

## Facets
- artifact type: library
- maturity: abandoned
- function: middleware
- domain: developer-tools, mobile-development
- platform: -
- tags: dependency-injection, service-locator, swift, property-wrappers, deprecated, inversion-of-control, ios, mobile
