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…)
NSSpain is one of the most well-known iOS conferences in Europe – that had been proven by the fact the tickets had been sold out before even one single speaker was announced. This was my first time at any iOS conference, so I was extremely excited about this whole trip. The talks were divided into two days, 19th and 20th September, so it was a great getaway before the summer ends.
Last few years, the WWDC keynote was mostly about introducing new features into Apple operating systems that were focusing mainly on the end user. It looked like Apple forgot that the letter D in WWDC means Developer. Everything was all about introducing new UI, new gestures or introducing new hardware. We were again and again wondering if something was changing and Apple would come up with some real game changer even for developers and again and again we were a bit disappointed that it never happened. But this year it’s a completely different story. (more…)
Interacting with the Tezos blockchain on an iOS device should be an easy task. With TezosSwift, we at Ackee are working to accomplish that goal. TezosSwift has been built with type-safety in mind and implements most of what you could possibly need for Tezos development on iOS. Parts of this tutorial are also applicable to Keefer Taylor’s TezosKit, a library that TezosSwift is based on.
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. ?
Programmers and supporters of the Ethereum cryptocurrency have gathered in Prague for the 4th DevCon, official Ethereum Foundation conference. It took place in the Congress Center between 30th of October and 2nd of November 2018 and associated meetups took place also at our Danube House within the wider Blockchain Week Prague event. Thanks to the development of Ethereum iOS DevKit we were one of the official grantees, we had two talks during the conference and we were in the center of action during the whole week.
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…)
