iOS Technical Interview Guide

Many devs, no matter their experience, get nervous at technical interviews.  It is normal you are human, you are looking for a job. You want to be hired and it’s normal to feel anxious when someone is evaluating you.

Many of us learn by doing. Creating apps and maybe we not think too much in the theory or the reasons why Swift does things in certain way. I needed 4 years to know the purpose of import Foundation at the beginning of a Swift file. But not having that knowledge did not have any impact in get hired in two jobs and publish my own app. But in a technical interview someone can ask why we need to import Foundation and I already know the answer: Foundation provides fundamental classes for data handling, file management, networking, date and time manipulation, and more. It's a crucial framework for building the backbone of your app.

This PDF file contains just a small sample of the complete guide. There are 20 questions, some basic, some more advanced. The complete guide contains 100 questions, 80 related to Swift and 20 are more general to iOS and development in general like frequent Git commands, Fastlane, VIPER, SCRUM, Package Manager and others.

My goal and hope is that studying this guide can lead you to get that job you are applying for. Best wishes and good luck. Persist studying an preparing yourself: You will get that job.
