Swift is more than just a language for building apps. In this talk, we will explore the Swift ecosystem including the compiler, the package manager, and the community-driven tools that make Swift development productive and enjoyable. We will look at how these tools work together and how you can contribute to the ecosystem.

One of the talks that Ayaka enjoyed watching is Boundaries by Gary Bernhardt. If you’ve seen a talk about functional programming in Swift, you’ve probably heard it being referenced. When she first watched the talk a few years ago, she understood the theory but wasn’t sure where exactly to apply the concepts. As she has been writing more Swift, she started to see that the concept of “Functional Core, Imperative Shell” applies not just to functional programming, but also to good engineering in general. In this talk, we’ll go over a couple of specific examples how these “boundaries” can help us write better, safer, and more future-proof Swift code. You don’t need to watch the Boundaries talk to understand this talk, but if you have time, definitely watch it because it’s a great talk.

Ayaka Nonaka

Ayaka leads the iOS team at Venmo where they write only Swift these days. She’s been doing iOS development since iOS 4 and loves writing Swift while listening to Taylor Swift.

At a high level, Swift is amazing and brings so much to us developers to use on a daily basis. However, there are many little-known things in Swift that can save us time and energy if we memorize a few key features. This talk will cover many features that look weird and translates them for beginners and experts alike to understand. Armed with this information, developers should hopefully be able to save lots of time decrypting the weird things they see on a day-to-day basis!
