Developer Guide


For Beginner Developers

For Complete Beginners!

If you’re completely new to Swift and iOS development (or need a brush-up), this is the series for you.

The iOS Apprentice is a series of epic-length tutorials for beginners where you’ll learn how to build four complete apps from scratch.

Each new app will be a little more advanced than the one before, and together they cover everything you need to know to make your own apps. By the end of the series you’ll be experienced enough to turn your ideas into real apps that you can sell on the App Store.

These tutorials have easy to follow step-by-step instructions, and consist of more than 1,100 pages and 500 illustrations! You also get full source code, image files, and other resources you can re-use for your own projects.

If you’re new to iOS and Swift, or to programming in general, learning how to write an app can seem incredibly overwhelming.

That’s why you need a guide that:

  • Shows you how to write an app step-by-step
  • With tons of illustrations and screenshots to make everything clear
  • In a fun and easygoing manner!

We’ll start at the very beginning. The first tutorial assumes absolutely zero programming knowledge but still shows you how to build an entire game from scratch.

The iOS Apprentice series doesn’t cover every single feature of iOS – it just focuses on the absolutely essential ones that you need to know.

Instead of just covering a list of features, the iOS Apprentice series does something much more important: it explains how all the different building blocks fit together and what is involved in building real apps.

You’re not going to create quick example programs that demonstrate how to accomplish a single feature. Instead, you’ll develop complete, fully-formed apps that are good enough to submit to the App Store!

Table of Contents

Section I: Getting Started with UIkit



Welcome to **The iOS Apprentice!** In this book, you're about to deep dive into the latest and greatest Swift and iOS best practices. Throughout this six-section book, you will build six iOS projects using both UIKit and SwiftUI. Good luck!


UIKit & the One-Button App

In this chapter, you will start building Bullseye using UIKit, Apple's existing way of building UI for iOS apps.


Sliders & Labels

Congratulations, you have a UIButton on the screen. It's time to start adding the UISlider which will be fundamental to the game.



You'll be well on your way of noticing the differences between building an app using SwiftUI and now UIKit. In this chapter you will deal with random numbers, adding rounds to the game and calculating the points scored.


Rounds & Score

It's time to start calculating the score for the gameplay in this chapter.



n this chapter, we will add some UIKit polish to the app and show an alert to the user.


The New Look

The look of your app is super important now as many apps flood the App Store. In this chapter, we're going to spruce up the UI with some fancy artwork.


The Final App

Phew! You have successfully created Bullseye using UIKit. In this final chapter of this section you will learn about supporting different device sizes and add some beautiful animations.

Section II: Checklists


Table Views

We're going to look at UITableView and UINavigationController in this Chapter. The majority of your apps in the future will be using these key frameworks provided by Apple.


The Data Model

In this chapter, we're going to introduce you to MVC (a programming design pattern) widely used in the Apple ecosystem. We will also separate our data logic into models.


Navigation Controllers

A UINavigationController is super important to control the flow of the navigation in our apps. We'll introduce you to it here and start building out the navigation stack ready for the next chapter.


Add Item Screen

A to-do list app is no good if we can't add an item, right? In this chapter we'll create a new screen to do just that.


Delegates & Protocols

In this chapter we'll introduce you to Delegates and Protocols and the concepts within. Again these are widely used across iOS development.


Edit Items

You've tackled adding a new item, we're now going to build out the functionality of our to-do list app with editing existing items in our list.


Saving & Loading

Our app is looking great, but every time you launch the app the data will be lost! Let's fix this by exploring how to save data and show a loading HUD.



Our app currently only manages one list of to-do list items. Let's explore having multiple lists in this chapter.


Improved Data Model

In this Chapter, we're going to improve our data model and make our app more scalable for the future. If you want to build any sort of list-based iOS app, this section is a good starting point for learning the basics. Of course, even if you aren't building a list-based app, this section has some basic concepts such as handling the navigation flow from one screen to another (and back again) that would be very useful to an apprentice iOS developer.


User Defaults

UserDefaults is a very popular framework provided by Apple and can be seen in many apps. Let's explore UserDefaults and why it will fit this project perfectly.


UI Improvements

In this Chapter, we're going to make some vital UI improvements.


Local Notifications

To finish Checklists it's time to explore LocalNotifications and their use.

Section III: My Locations


Swift Review

You have made great progress. You have built your first app using UIKit which is some achievement. Whilst we have been writing the apps using Swift, you will need some additional theory to level up your knowledge. In this chapter, we will go into details about some of the Swift language, such as Variables, Constants, Types, Methods & Functions, Loops, and Objects.


Get Location Data

Are you ready for the final app challenge? In this chapter, you will commence the final app MyLocations. It's all about using the Core Location framework and displaying using MapKit.


Use Location Data

You've learned about getting GPS coordinate information. Now it's time to deal with GPS errors, improving GPS results and testing on real devices to mimic real-world scenarios.


Objects vs. Classes

This question will most likely crop up in your next iOS interview. It's time to put the toolbox down and learn some theory. Expect to learn about classes, inheritance, overriding methods and casting an object.


The Tag Location Screen

In this chapter, you will be picking up the toolbox again and building our tag location screen. This involves building out some TableViewCells, displaying location info and adding a category picker.


Adding Polish

Who doesn't love adding a bit of polish? It's time to start making it look more like an app ready for the App Store. We will improve the experience of the app and add a loading 'HUD'.


Saving Locations

At this point, you have an app that obtains GPS coordinates and allows the user to tag the location. We're going to be deep-diving into Core Data, the object persistence framework for iOS apps.


The Locations Tab

Now that you can persist the data to Core Data, we're going to explore displaying this data in the TableView. Learn about TableView sections, NSFetchedResults and add functionality to delete tagged locations.



Showing a list of locations is great, but not very visually appealing. In this chapter, you will learn about MapKit, the awesome map view control giving in the iOS toolbox.


Image Picker

UIKit comes with a built-in view controller, UIImagePickerController that lets users take new photos or select existing ones. In this chapter explore this controller and how best to display the image on the screen.


Polishing the App

You have made it this far! It's time to give MyLocations a complete makeover. Prepare your pixel paintbrush for this chapter and let's get your creative flair at the ready. In this chapter you will cover the map screen improvements by adding icons, polishing the main screen and adding some cool effects to the app.

Section IV: Store Search


Search Bar

One of the most common tasks for mobile apps is to talk to a server. In this final UIKit app you will build StoreSearch. In this chapter, you will build the first screens, add fake searches and create the data models.


Custom Table Cells

Before your app can search the iTunes store for real, we need to make the app look visually appealing. In this chapter, you will cover custom table view cells and nibs. Learn a little more about using git and the debugger right inside Xcode.



Networking you say? Start querying the iTunes web service by using HTTP requests. An introduction to JSON and best to convert them into data models and finally look at how best to sort results.


Asynchronous Networking

Phew! You will rarely want to block the main thread with a network request. In this chapter, we will explore asynchronous networking and finally showing an activity indicated to let the user know something is loading.



The iOS toolbox and the Swift language has many tools for our disposal, including URLSession. In this chapter, we will explore URLSession and it's many benefits. Downloading the iTunes artwork and how best to merge your git changes.


The Detail Pop-Up

In this chapter, we will create a detail pop-up view when a user taps a row in the TableView. We don't want to display too much information now, do we?


Polish the Pop-Up

We're about to get the polish back out again. The detail pop-up view is working well but we can display the information better. Learn about dynamic types, gradients for the background and let's explore adding some more animations.



Users expect apps to work in both portrait and landscape. They also expect the app to look great in both orientations. In this chapter, we will learn about adding a completely different user interface for landscape vs. portrait.



The final app is looking great. You should put your feet up and grab a coffee! Programming is all about building new pretty features but when you join an existing company with an existing code-base you have to learn about the best ways to refactor existing code. Let's go!



So far our app works great in English. But if you want your app to go international you must support multiple languages and formats. In this chapter, you will explore adding support for a new language and look at regional settings.


The iPad

Even though the app works _OK_ on the iPad, but it's not exactly optimized for the iPad. In this chapter, we're going to explore universal apps, the split view controller functionality, and dark mode support.


Distributing the App

Are you ready to ship to the App Store? Finally, you will learn the key fundamentals on how to ship the app to the App Store, including the Apple Developer Program, beta testing using TestFlight and finally submitting to the App Store.

Section V: Getting Started with SwiftUI


Hello SwiftUI

Take the first step of building a SwiftUI game by creating your iOS project, add some interactivity with a UIButton and learn all about the anatomy of an app.


Building the Bullseye Interface

Bullseye is all about the slider, get sliding in this chapter by using the Slider control and start constructing the first steps of a working game.


Polishing Bullseye

Apps are known for their clean and simple UI. We will spice up the artwork in this chapter and make it look like a *real* game. We will also make improvements to landscape orientation.

Section VI: Checklists


Swift Playgrounds, Classes & Structs

It's time to start your next iOS project. Are you ready for the challenge? In this chapter, we will commence our next app using SwiftUI, Checklists. Before we dive into building Checklists this chapter will cover a Playgrounds project and explore some core concepts.


List Views

It's time to start your next iOS project. Are you ready for the challenge? In this chapter, we will commence our next app using SwiftUI, Checklists. Prepare for NavigationView, Arrays, Loops and removing items from the list.


A "Checkable" List

A Checklist app without being able to tick off the items? In this chapter, you will add the toggle for a Checklist item.
