Getting ready for a job interview is tough work, so I’ve prepared a whole bunch of common questions and answers to help give you a jump start. But before you get into them, let me explain the plan in more detail…
Watch the video here, or read the article below
Once you’ve polished your resume, prepped your portfolio, and applied for the job of your dreams, you still have one major hurdle to get through: the interviews, which might be an hour if you’re lucky, or potentially a day or two if it’s for a bigger company or a more senior role.
I’ve done a lot of job interviews in my time, and I’m also responsible for maintaining the world’s largest collection of interview questions for Swift developers – questions that are specifically and directly used by countless companies around the world. So, I tell you the kinds of things you’re likely to be asked in your interview, but that’s not enough by itself.
Yes, if I were to tell you all the most popular interviews questions, it would give you something to plan for and prepare for, and hopefully would give you extra confidence when walking into the interview that you have good answers ready. But it wouldn’t do much to help you structure those answers – it wouldn’t give you guidance on what to include in your answer, or how to structure things, and so on.
So, this section of Hacking with Swift+ is designed to solve that problem: not only have I selected the most common interview questions for you, but I’ve also answered them in detail, explained the approach I would take, and often provided code samples to, so you have the complete toolkit needed to really ace your next interview.
You’ll see a few things come up regularly, and I want to repeat them here:
There’s one bonus tip that isn’t about iOS: if they ask you whether you’d like some coffee or something, say yes. I don’t care if you don’t want coffee – ask for tea, or water, or soda, or something, just take the drink. Why? Because when they ask you a tough question, you can take a sip of your drink and pause for just a moment, and in doing so buy yourself a few seconds to phrase your answer as best as you can. Seriously, it works – take the drink!
Here's just a sample of the other tutorials, with each one coming as an article to read and as a 4K Ultra HD video.

UPDATED: While I’m sure you’re keen to get started programming immediately, please give me a few minutes to outline the goals of this course and explain why it’s different from other courses I’ve written.
SwiftUI gives us a modifier to make simple shadows, but if you want something more advanced such as inner shadows or glows, you need to do extra work. In this article I’ll show you how to get both those effects and more in a customizable, flexible way.
Swift’s optionals are implemented as simple enums, with just a little compiler magic sprinkled around as syntactic sugar. However, they do much more than people realize, and in this article I’m going to demonstrate some of their power features that can really help you write better code – and blow your mind along the way.
Generics are one of the most powerful features of Swift, allowing us to write code once and reuse it in many ways. In this article we’ll explore how they work, why adding constraints actually helps us write more code, and how generics help solve one of the biggest problems in Swift.
Phantom types are a powerful way to give the Swift compiler extra information about our code so that it can stop us from making mistakes. In this article I’m going to explain how they work and why you’d want them, as well as providing lots of hands-on examples you can try.
Assertions allow us to have Swift silently check the state of our program at runtime, but if you want to get them right you need to understand some intricacies. In this article I’ll walk you through the five ways we can make assertions in Swift, and provide clear advice on which to use and when.
Trees are an extraordinarily simple, extraordinarily useful data type, and in this article we’ll make a complete tree data type using Swift in just a few minutes. But rather than just stop there, we’re going to do something quite beautiful that I hope will blow your mind while teaching you something useful.
It’s not hard to make a basic property wrapper, but if you want one that automatically updates the body
property like @State
you need to do some extra work. In this article I’ll show you exactly how it’s done, as we build a property wrapper capable of reading and writing documents from our app’s container.
In this article we’re going to look at the map()
function, which transforms one thing into another thing. Along the way we’ll also be exploring some core concepts of functional programming, so if you read no other articles in this course at least read this one!
In this article I’m going to walk you through building a WaveView
with SwiftUI, allowing us to create beautiful waveform-like effects to bring your user interface to life.
Anyone can write Swift code to fetch network data, but much harder is knowing how to write code to do it respectfully. In this article we’ll look at building a considerate network stack, taking into account the user’s connection, preferences, and more.
In this article you’ll learn how memoization can dramatically boost the performance of slow functions, and how easy Swift makes it thanks to its generics and closures.
Before you dive in to the first article in this course, I want to give you a brief overview of our goals, how the content is structured, as well as a rough idea of what you can expect to find.
SwiftUI’s humble Button
view is actually capable of doing remarkable things if you take the time to customize it. In this video I’ll be walking you through the ButtonStyle
protocol, showing you how we can use it to make great-looking and reusable button effects.
Broken record alert: explain the fundamental technical difference between the two, try to provide an opinion on which you think works better, then provide some kinds of examples of where each might work well.
UPDATED: Everything we’ve done so far has produced a serviceable app, although in the future we’ll add a lot more functionality and cross-platform support. But before we get near to those, I want to change gear and focus on making our existing code better. This is where the real work begins!
This challenge asks you to let users switch map styles, show alerts for authentication errors, and create a view model for EditView
. Let’s tackle it now…
To kick off the process of cleaning up our code to work well on macOS, we’re going to tackle the easiest one of our views: Awards. This means fixing up its navigation and button styles so it looks and feels great on Mac.
In this article we’re going to look at how easy it is to rebuild the iOS lock screen. Yes, this isn’t hard, but along the way I think you’ll pick up a few cool SwiftUI tricks, including better date formatting, haptic buttons, and more.
This question comes up a lot, but I’m always wary of it because it places a lot of emphasis on unpaid work out of hours, which particularly affects people who already have extra responsibilities caring for children or elders.
