We are making the 4-part series “Tour of Sharing” free for everyone to watch! In these 4 episodes we introduce a few of the most important concepts in our new Swift Sharing library, which provides a universal solution to persistence and data sharing across your app.

We cover the 3 main forms of persistence strategies that come with the library:

• appStorage: This tool allows you to persist small bits of data to UserDefaults. We also show how this tool compares to what SwiftUI provides out of the box (spoiler: ours has better support for animations and works anywhere in an app, not just a SwiftUI view), and we show how it provides a type-safe interface to UserDefaults.

• fileStorage: This tool allows you to persist more complex data structures to the file system. We also demonstrate how it observes changes to the file on disk so that any external writes are automatically kept in sync with the state in your app.

• inMemory: A simple tool for sharing state globally with your entire app, but the state is never persisted. It is automatically cleared with each launch of the app.

These 3 persistence strategies allow you to easily persist and share state across your entire app, but it’s also only half the story. The library allows one to build their own persistence strategies for speaking to other external storage systems. You can build one for SQLite, Firebase, API servers, Wasm, and more… your imagination is the only limit!

These topics will be the focus of next week’s episode, but until then be sure to catch up on our “Tour of Sharing” today!
