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

• Quick hardware test, hold D on boot
• Serial number check at apple https://checkcoverage.apple.com, see for confirmed purchase date, expired warranties (or not)
• No iCloud should be linked (Settings -> iCloud), ‘find my mac’ should be off
• Check if the Firmware password is set, Cmd-R during boot and go to Security settings, should be off
• Turn Firewault off (Settings -> Security & privacy)
• Model hw (A1502 for example) and SN should match the HW specs (check on https://everymac.com/ultimate-mac-lookup/)
• Battery cycles check
• Overall state, screen hinges
• Keyboard, all keys
• Screen test, search for pixels (https://www.eizo.be/all-monitors/accessories/software/monitor-test/)
