Having fun(ctions) with Swift

Date: October 17, 2018

Abstract: The talk aims to show you how (& why) to incorporate various heresies (such as free functions and loads of custom operators) into your Swift development toolkit. You may ask: "what the heck, why would I ever want to do that"?! The answer is simple: for extreme testability and composability. Sounds interesting? Come by for deep dive into the functional world! 👍

Always give 100% (revised)

Video: youtube.

Date: September 18, 2018

Abstract: The talk is about unit testing and developing iOS apps in TDD with Swift. It will cover a plethora of tips and techniques that me and the team has discovered en route to the app with 200K lines of Swift at nearly 100% code coverage. The talk will highlight the techniques of structuring the code so that it is easily testable. It will demonstrate how to overcome common pain points, such as testing view controllers or the test-first approach for views built entirely in code. It will also show how to refactor the test code for better readability, for example using Sourcery code generation tool. It doesn't matter whether you have never written a single test case or are a veteran looking to push the testing to the limit. If you are like me and want the days of debugging through piles of unmaintainable code to be over, this talk is definitely for you!
