iOSCon 2018

Conferences are a great opportunity to exchange knowledge and experiences with the fellow developers. The iOS community is pretty cool – there are a lot of fantastic people who are building apps and tools, but also share knowledge with everyone who wants to work as an iOS engineer.

I’m very excited to attend iOSCon 2018, where I will be speaking about Understanding language on iOS. In the talk, we will see approaches that can help us in tackling one of the most challenging tasks in computer science – understanding what the users are trying to say. The talk will cover technologies ranging from SiriKit, Dialogflow, and CoreML, up to doing it everything by yourself, using Apple’s NSLinguisticTagger. If these technologies are interesting for you and want to learn more about them, come and see my talk on 23rd March @ CodeNode in London. For even more details, you can also check my new book Developing Conversational Interfaces for iOS, published by Apress.

Common iOS development mistakes


Developing iOS apps is fun and challenging. During this process, we sometimes make bad decisions and mistakes, that can have impact on the quality of the app (both technical and from the user’s perspective). Some of those pitfalls can cause crashes in our apps, making users angry. Others can make the maintenance of the app a nightmare, making developers angry. In this post, we will see some of the more common such errors, ranging from the most trivial ones that a careless developer can make, to the bigger impact ones, that a tech lead might not foresee and send the project to hell.

Xcode build settings tour


Build settings in Xcode define how your app is going to be built. Usually, when your app shows build errors or it fails to validate on iTunesConnect, build settings is the place that you should search for errors. Is some path configured in a wrong way? Are the architectures properly set? What about the linker flags? In this post, we will look at several build settings (not all since there are too many), and what errors they might cause. Here’s a list of all the settings for reference.

Writing a technical book

Recently, I’ve finished writing a technical book, called Developing Conversational Interfaces for iOS, which will be published by Apress early next year. Writing a book is a very different experience than writing code or blogging. That’s why in this post I will share my impressions from that interesting journey. I hope other developers who want to try themselves out in the book publishing industry will consider my findings helpful.

Trendy topics for 2018 and beyond

The previous year was very exciting in terms of technology. A lot of new concepts, tools and frameworks were introduced, laying the ground for software developers and entrepreneurs to introduce cool new innovative products in the following years. 2018 would be even more exciting, with lots of improvements in the already existing areas, that will (hopefully) make our lives better and more efficient. In this post, we will see what I believe would be the trendy topics for 2018.

Drawing charts on iOS


Data visualisation helps us better understand the information and statistics our systems have collected. Having different views of the data, in different types of charts, like line charts, bar charts, pies etc, is really useful for anyone who has to make decisions based on data. Since users expect to have everything now on their mobile devices, we will see in this post how we can draw such charts. We will create three different types of visualisations, the first two with the awesome Charts library, and the third one will be our custom implementation.
