Have you ever fixed a bug in your code and wondered if you made that mistake elsewhere? Wouldn’t it be great if you could teach the Swift compiler to catch that bug next time you wrote it? In this talk, we’ll learn how you can build custom static analysis tools for Swift to make sure you never write the same bug twice.

If your app is the product you ship to your end users, your code’s API is the product you ship to your teammates, external developers, and — perhaps most importantly — future you. Daniel takes a brief look at some of the points to consider when designing an API to be proud of, before delving into some real-world challenges he faced when things started to get a bit more tricky!

Daniel Kennett is an independent iOS and Mac developer currently working on Cascable, a tool for working with WiFi-enabled digital cameras. He previously worked at Spotify as an OS X and iOS engineer.

App architecture is a topic that is very commonly discussed in the iOS developer community, but most conversations tend to focus on design patterns and letter combinations—In this talk, John will take a step further and explore how system design can be a really powerful tool to create well-rounded architectures for apps of any size and complexity.

John Sundell builds apps, games & developer tools. He also makes Swift by Sundell – a weekly blog & podcast about Swift development. He has worked for companies like Volvo & Spotify, and is now an iOS freelancer. He’s the creator of several open source projects and loves to share his work with other developers.

When it comes to machine learning, the abundance of tools and frameworks that are made available today overwhelms developers who are new to the field and slows down their learning process. In her talk, Meghan will walk us through which ML tools to use for what purposes, be it training a model or doing on-device prediction, while also covering some of the newly introduced CoreML APIs in WWDC 2018.

Meghan Kane is an iOS developer at Novoda in their Berlin office. She is the co-creator and instructor of a Udacity course on Core ML. When not coding, she can usually be found reading at a coffee shop or cycling. In her former life, she lived in the US and studied Mathematics & CS at MIT.

Swift gives us a dazzling array of features we can deploy to really screw up our code, so why use just one when you can have them all? Sometimes it’s easier to learn what’s right by seeing what’s wrong, so in his talk, Paul will walk us through example code and fix the issues that come up.
