Do you prefer iOS and Apple is your thing? We are glad for that - iOS Developer is always welcome.
However, we have some requirements.
We don't know, what programming language you use, but we use Swift and we'd like you to have at least a year of experience with it.
Knowledge of libraries for networking, autolayout and data persistence is also needed.
You don't have to be master of all that, but you will definitely get in touch with those things as we use them daily. Working skill with Git or SVN is a must-have.
We will appreciate if you have knowledge of project architectures and experience with some of them. Knowledge of reactive programming is a huge advantage.
