When Apple meets AR

It's time for AR! The last WWDC was full of announcements: one of them concerns Augmented Reality features now offered through iOS 11.

Unidirectional Dataflow with ReSwift

ReSwift is a Redux-like implementation of the unidirectional data flow architecture in Swift. It helps you to isolate state inside your app and manage state transitions and propagation of state to various components in your app in a well-defined, predictable and testable fashion.

How I came with peace with Core Data.

Mobile applications tend to need more local data storage nowadays. CoreData is a powerful tool for storing and querying locally stored information. In the first glance it may appears a little complicated to setup and use its power, at least this was the case to me. This talk aims to present a quick and easy way to setup Core Data. If you are interested to take a look before the meet-up, checkout the github link below.

How moving to manual dependency management saved us app startup and build time.

Cocoapods is a de-facto standard in iOS dependency management. Nevertheless, with complex project structure it becomes hard to maintain. I'll tell you a story of transitioning our project from Cocoapods to manual dependency management, which improved our project structure, build time and app startup time.

Recursive Enums, Value Types in Swift & Performance Analysis

One feature in Swift that is often overlooked are indirect enum cases. With those we can create tree based data structures that are benefiting from Swifts efficient value types. In my talk I will explain this, using the an example called KD-Tree a k-dimensional binary space partitioning tree that is used for nearest neighbour searches among other things. Furthermore I will present performance results that present the advantages of of value types in general.
