VIPER: our view on the issue

After a year of using VIPER architecture in the development of applications such as LiveJournal, Afisha, Kassa we are ready to share the results of our experience. How and why we use VIPER, what advantages and disadvantages of this approach we see compared to MVC, MVVM or the absence of any architecture. We will also tell you about some of the decisions and agreements that have been produced in course of joint development for better standardization of processes.

Critique of “library” approach in developing for Android

Recently there is an explosion of interest to the development of Android applications using the external SDKs and frameworks. First of all, this is due to the energetic activity of such companies as Square and Facebook.

And while we generally have no questions concerning the libraries that perform purely utilitarian functions and help without writing any extra code, the excessive use of libraries and frameworks that impose their rules of the game on top of the native one often leads to negative results.

The aim of the report is to review the negative aspects of the use of such libraries as EventBus, RxJava, Mortar etc. compared to the development using native tools Android Framework, and explain to the audience the idea that any library, framework or SDK is primarily a tool, the efficiency of which depends on the understanding how it works in the context of a specific task.

Swift iOS Architecture with FLUX in mind

With the release of Swift, programmers received new opportunities under iOS platform: value types, associative enumerations, tuples, support of a functional paradigm. To make the most of all these innovations it is necessary to rethink the approach to architecture designing. In my report I will demonstrate a working and pragmatic approach to creating iOS apps using the Swift programming language.

Effective Android Development

The efficiency of your software engineering work depends not only on your deep knowledge and expertise, but also on the toolset you select, and how well you use the tools.
In this talk, I will discuss some tools and approaches that will help you to increase your productivity as an Android developer and decrease the amount of “monkey work” being done day-to-day. My talk will show a collection of solutions used by our team to develop product with 10+ million downloads. Key points:

• Android Studio: configuration tricks, little-known features and plugins
• Test devices: emulators vs real gadgets, cloud test platforms
• App performance: what and how to measure, how to make your app work faster
• Gradle hacks: build your app faster and add more flexibility for different build types

The information and examples provided will be interesting for both beginner and experienced developers.

Windows 10 – one application for all platforms

After the release of the latest operating system from Microsoft, developers get a great opportunity to write single code, develop single view and get a single application that runs on all Windows 10 devices. Just imagine - you do not need to worry about various API on different platforms, different design guidelines. But how could you use this opportunity for the 100%? How could you create a high-quality mobile app that works everywhere, using all existed possibilities?

In this talk, I will tell you how to create a high-quality application for Windows 10, what problems you may encounter and how to solve them and the new procedure of compiling .Net Native.

In his free time plays football, does all kinds of experiments in the development and propagandizes C# mobile development.

Data transfering: faster, stronger, better and not harder

Almost all mobile apps should communicate with server or even with each other, some of them should store something and definitely all of them should work as fast as they can. One of the bottlenecks in performance of these apps is operations with data. Actually almost all apps are all about the data, they send it, store it, process it, receive it and somehow show it to the user. So to make your app really fast you definitely need to find a way how to make data processing really fast.

So let’s discus what tools do we have right now for this, how and when should we use it and how this will make your users happier.

Azure App Services for creating backend of the mobile applications. The example of the deployment of Parse Open Source on Azure.

Mobile telephones enter deeper into our lives from year to year. At the same time, not only do they in a private life, but also in working one. A mail, a calendar, a corporate messenger, an office suite and specific applications even now allow us to keep the business on the pulse and carry out the work, being far away from a computer. Being always online is a modern trend. Despite the fact that every year the mobile devices become more productive, we still cannot bring all the business logic on the client side. On the other hand, the mobile devices run on different platforms and the application support issue becomes particularly critical if different commands work over the same functionality for different types of devices.

The cloud helps us in addressing these issues. Bringing the business logic of applications to a centralized backend, we can achieve the ultimate efficiency of the application operation and facilitate support.

In this report, we will talk about the principles of building of the fault-tolerant and scalable server-based applications for mobile devices. We will have a look at the functionality of the Azure cloud services for the mobile application developers, as well as we will have a look at the process of the deployment of these solutions, as exemplified by the Parse platform, which recently became the Open Source.

Faster than light

In my report, I will share the experience that I gained while working at http://uberchord.com: I will tell why we returned from MVVM back to the MVC, what is the first experience of using Swift in the production of a major project, how it is possible to increase the conversion of users by 10 times just in 2 weeks of work, as well as I will show the results of my little experiment of printing any application in Featured by Apple.

The Flexible Layout Kit (how we got rid of web views)

Content is King! At Zalando, our content is changing every day. fashion trends come and go and new items enter our warehouses every day. Discounts happen over night and every so often we want to present a new feature on a landing page. On websites these changes can be pushed to the public within seconds. But with Native apps we have release cycles measured in weeks or at least days.

In this talk, I’ll cover how we tackled this problem at Zalando by creating a framework we call Flexible Layout Kit. Flexible Layout Kit is a layout engine that translates JSON content into native iOS interfaces. it’s made up of a collection of elements that can be contained inside each other to form amazing native UI.

Zeyad is an iOS Developer at Zalando SE. He has been a fan of iOS ever since iOS 1.0 and has been writing apps since version 4 came out. From working with startups to creating his own. And now he's part of the amazing Zalando team that allows us to buy pants from our iPhones :D
