Tezos smart contracts have matured a lot – and it’s time to use them in iOS apps, closer to the users’ hands. 😉 Throughout this tutorial we will write a smart contract using SmartPy.io and then move to Xcode and get a hands-on experience with interacting with our contract in Swift using generated code from tezosgen. Note that this tutorial will touch on the most important parts of RateMyTeam app and is not a complete step-by-step tutorial. (more…)
Two years ago, my colleagues participated in a weekend hackathon and came up with an idea to create a Rock-Paper-Scissors game for Facebook messenger. The real-world RPS game is simple and pretty much everyone knows how to play it. The mobile app didn’t aim to add cool new ways to play the game and tried to be as simple as possible.
All our apps are developed in several different environments. Let’s have a look at what we call an environment, what the motivation to have different environments in one app is and what type of inconveniences it could bring. We’ll also unscover a part of our technological stack which helps us to do it the way we do it. ?
Performance matters. It is especially true for audio performance, where you want the audio to be as smooth as possible. In this article I will have a look at various available options you can use in your high performance audio app on Android. But first, we need to understand the motivation behind high performance audio. Why is it important? What problems are we trying to solve? What apps are we actually talking about?
Ethereum smart contracts have a wide variety of use cases, but until now it has been quite difficult to call them from your iOS app. Well, that has changed! Just by using Ethereum iOS Dev Kit and EtherKit, you can get started in no time. At the end of this tutorial you will be able to call any public contract function that is defined in its ABI (Application Binary Interface). (more…)
The Material Design 2.0 comes with couple of new and interesting concepts. One of them is the emphasis on shapes of your components. There is one way to create very nice complex shapes in a very simple way which is called MaterialShapeDrawable. Is it useful for app development? Is it easy to use enough? Let’s find out.
