## What it is
Unwrap is a free iOS app by Paul Hudson that teaches the Swift programming language through nearly 100 video lessons, interactive reviews, and daily coding challenges. Its source code is open so developers can study how the app is structured and contribute improvements.

## Use cases
- learn swift on my iphone
- interactive swift tutorials for beginners
- practice writing swift code on ipad
- daily swift coding challenges
- study how an ios app is structured in swift

## When to choose
- you want to learn Swift fundamentals interactively on an iPhone or iPad

## When to avoid
- you need to learn SwiftUI or UIKit app development rather than the Swift language itself
- you want a desktop or web-based learning environment
- you need redistributable assets - the code is MIT licensed but assets are not
