Hello all,

'XCoordinator - A powerful navigation library for iOS based on the Coordinator pattern'
by Paul Kraft - QuickBird Studios

Let’s redefine how navigation is done in iOS. This presentation will introduce you to the iOS navigation library XCoordinator. Being based on the Coordinator-pattern, it answers the common question: “How does an app transition from one ViewController to another?“. It’s a navigation framework for decoupling complicated navigation and transition code from your view components. We’ll start with a light introduction to the Coordinator-pattern and show the pros and cons of it. Afterwards, we will dive into XCoordinator and introduce it to a small project.


'A generic solution for offline persistence of user interactions' - by Karim Alweheshy - United Internet AG

Ever worked with offline data on iOS? Then you might also have written some code to avoid/fix race conditions. Synk is our in-house solution in 1&1 using Core Data and URLSession. Not only it avoids race conditions on the lowest levels, it asserts sequential executions, it also helps with (re-)authentication, it executes requests on the background, retries in case of client error and it persists to CoreData.


We also have a Slack channel that you can join, message us your email in a private message and we will add you.
