This is the perfect time to get full access to all of our videos. In the past year we have explored many advanced topics of Swift and SwiftUI, including:

• Modern Persistence

  Our current ambitious series series of episodes asks “What should the persistence layer in a modern application look like?” We attack this problem head on by rebuilding Apple’s Reminders app from scratch, and we do not shy away from its most complex features, including complex schemas, foreign key relationships, queries, and more.

  And soon we will be attacking multi-device synchronization of SQLite databases and sharing data with other users. You won’t want to miss it!

• SQLite

  We dedicate a series of episodes to SQLite, one of the most impressive software projects in the history of software development. Gaining an expertise to SQL and SQLite can be a huge boon to your career as it is a far reaching skill beyond the Apple walls, and it provides an amazing set of tools for building data-intensive applications with very little work.

• SQL Building

  There’s no better way to deeply learn SQL than to build a library that is capable of representing any SQL statement as a type-safe and schema-safe expression in Swift. So, we designed a series of episodes that shows how to use some of Swift’s most advanced features (parameter packs, existentials, key paths, result builders, …) to create a SQL building library that rivals any other SQL building library in any other language out there.

• Back-to-basics: Equatable and Hashable

  We go back to our roots by dusting off the mathematical foundations of Equatable and truly understanding how to properly conform to this ubiquitous protocol. While straightforward for structs, we make the surprising (but 100% correct) discovery that classes should almost never use their stored data to implement == or hash(into:), and doing so will lead to disastrous results.

• Modern UIKit

  No one was asking for a modern UIKit series, but that doesn’t mean it didn’t deserve to be made! We showed how the Observation framework in Swift allows us to completely revolutionize how one writes UIKit apps. We can provide powerful state management tools and navigation tools that allow us to write UIKit features in a style that looks very similar to SwiftUI.

• Cross-Platform Swift

  Did you know that Swift runs on more than just Apple’s platforms? It runs on Linux, Windows, and can even run directly in a browser via Wasm. We explore this topic by building a moderately complex application that runs in the browser. It manages state, makes network requests, and even performs navigation!

And the above is only scratching the surface of what we have covered in the last 6 years since Point-Free launched, and we have some truly exciting episodes planned for the rest of the year, including a powerful new way to automatically synchronize SQLite databases to multiple devices using CloudKit.

And that is just barely scratching the surface of what we offer on Point-Free. We hope you’ll join us for all of the great material we have planned for the rest of the year!
