Test task

Description

github.com has public API to get list of users: "https://api.github.com/users". There are helpfull parameters like "per_page" and "since", check them. You need to create iOS application that displays list of github users loaded into table. Each row should contain login, profile link (html_url) and avatar preview(100x100). Tap on user should result in opening list of his followers.

Requirements

• application should be written in Swift (Swift 3.0 is preferred, but 2.3 will do just fine)
• source code should be available on github.com
