Our New Surprise Book

We have a brand new surprise book out in early access: Mastering Git by Tutorials!

1) Mastering Git by Tutorials

Mastering Git by Tutorials

If you’re frustrated with Git and want to stretch your knowledge beyond simple branching and merging in GUI clients like Tower or GitHub Desktop, then this is the book for you!

Mastering Git by Tutorials expands on the concepts touched on in our popular Beginning Git and Mastering Git video courses. This book dives deep into the Git internals, shows you how to fix your repo when Git behaves unexpectedly, reveals how rebase, cherry-pick, and merge really work behind the scenes, and even covers the major Git workflows in use today.

Whether you’re a novice with Git, or an advanced developer who needs to fix the messes other people have made of your repository, then this is the book you can’t do without.

What’s inside Mastering Git by Tutorials:

  • Git Internals: If you’ve been using Git for a while, you might be wondering how it actually works. See how Git is built on top of a simple key-value store-based file system, learn about the elegant and efficient branching model inside of Git, and discover the power this provides to you as a distributed development team.
  • Merge Conflicts: Although merging sometimes seems like more of a headache than it should be, it’s one of the most useful and elegant bits of Git source control. In this chapter, you’ll learn how to handle merge conflicts, which occur when Git can’t automatically merge your changes changes.
  • Rebasing to Rewrite History: Rebase has way more uses than just as a replacement for merge. Rebasing offers the ability to completely rewrite the history of your git repo, should you need to squash commits, or clean up a messy branching history.
  • Gitignore After the Fact: Gitignore is easy, right… right? If you’ve been using it for a while, you’ll know that this isn’t always true. Discover how you can fix problems with your .gitignore, such as clearing out files that have been accidentally committed to the repository, and how to manage merges that affect ignored files.

And if you’re getting started with Git (or want to understand how the basics of Git work under the hood), this book has a whole first section devoted to Git fundamentals, including:

  • Cloning a Repo: It’s quite common to get your start with Git by creating a copy of somebody else’s repository. Discover how to clone a remote repo to your local machine, and what constitutes “forking” a repository.
  • The Staging Area: Before you can create a Git commit, you have to use the “add” command. What does it do? Discover how to use the staging area to great effect through the interactive git add command.
  • Git log and Viewing History: There’s very little point in creating a nice history of your source code if you can’t explore it. You’ll discover the versatility of the git log command—displaying branches, graphs and even filtering the history.
  • Branching: The real power in Git comes from its branching and merging model. This allows you to work on multiple things simultaneously. Discover how to manage branches, and exactly what they are in this chapter.
  • Syncing with a Remote: You’ve been working hard on your local copy of the Git repository, and now you want to share this with your friends. See how you can share through using remotes, and how you can use multiple remotes at the same time.
  • Merging: Branches in Git without merging would be like basketball without the hoop—fun, sure, but with very little point. In this chapter, you’ll learn how you can use merging to combine the work on multiple branches back into one.
  • Stashes: Git stashes offer a great way for you to create a temporary snapshot of what you’re working on, without having to create a full-blown commit. Discover when that might be useful, and how to go about it.

One thing is certain: once you’re done with this book, you’ll know more about working with Git than most other developers you’ll meet!

This book is available as part of our early access program; when you buy the book now, you’ll receive a free update when the book is available in full!

Our Newest Books

It’s been a busy year, trying to stay on top of everything Apple announced at WWDC 2019. We’re thrilled to present the following updates to our books covering the newest Apple technologies of 2019: SwiftUI, Catalyst and Combine!

2) SwiftUI by Tutorials

SwiftUI by Tutorials

SwiftUI by Tutorials is designed to help you learn how to transition from the “old way” of building your app UI with UIKit, to the “new way” of building responsive UI with modern declarative syntax with SwiftUI.

This book is for readers who are comfortable building Swift apps and want to make the exciting leap into building their app UI with modern, declarative code.

What’s inside SwiftUI by Tutorials:

  • Introduction: In this chapter, you’ll get an overview of the book as a whole, as well as the apps you will be building as you learn the fundamentals of SwiftUI!
  • Integrating SwiftUI: The previous chapter showed one type of integration: how to create a data dependency on a “traditional” reference type. This chapter shows how easy it is to include a SwiftUI view in a UIKit app, and vice versa.
  • Intro to Controls: Text & Image: In this chapter, you’ll learn about two of the most used controls, Text and Image, and how to customize them using modifiers.
  • State & Data Flow: In this chapter, you’ll learn binding data to the UI, reactive updates to the UI through state management, and an in-depth usage of the attributes introduced in the SwiftUI introduction.
  • Controls & User Input: In this chapter you’ll learn about other controls, like TextField, Button, Toggle, Slider, Stepper and pickers.
  • Introducing Stacks: In this chapter you’ll learn how to use container controls, such as stacks, GroupBox, Form and Group.
  • Lists & Navigation: In this chapter you’ll learn how to display lists of items, and how to navigate between views.
  • Testing & Debugging: In this chapter, you will learn about creating user interface tests and debugging your app.
  • Handling User Input: This chapter will cover user updates of the interface, including how to easily test a SwiftUI interface, how to manage the flow of screens throughout a complex app, and how to deal with gestures, including the development of a custom gesture.
  • Drawing & Creating Custom Graphics: In this chapter, you will learn how to create drawings and graphics in your app.
  • Animations & Transitions: In this chapter, you will learn how to use animations and view transitions in your app.
  • Complex Interfaces: In this chapter, you will learn how to use existing custom controls from SwiftUI and how to build complex interfaces in Swift.
  • Apple Ecosystem/Frameworks: This chapter shows how a SwiftUI iOS app can be easily adapted to other Apple platforms — macOS, watchOS, tvOS — focusing on how to make best use of the device, its unique features and how it handles input.

SwiftUI by Tutorials is 100% complete and available on sale today for the special launch price of $49.99!

3) Catalyst by Tutorials

Catalyst by Tutorials

Catalyst by Tutorials shows you how to take all of those great apps you’ve build on iOS and run them right on macOS. But like everything else with Apple, it’s not always as straightforward as you’d like!

This book shows you how to design your apps to work well on macOS, what you can and can’t port between the two platforms, and any other “gotchas” to keep an eye out for when building apps under Catalyst.

What’s inside Catalyst by Tutorials:

  • Setting the Scene(s): In this chapter, you’ll learn how to enable a feature that has been available since the beginning on the Mac, and has just arrived with iOS 13 on the iPad, multi-window support.
  • Adding Some Context: In this chapter, you’re going to learn all about context menus, adding support for long-press menus on iPad and how those menus will automatically port to Mac.
  • The Keyboard: In this chapter, learn how to use keyboard commands to navigate across a list and delete items, as well as the UIKeyCommand and setting first responder.
  • Preferences & Settings Bundle: Learn layout preferences, and override individual items from dark mode, similar to Mail.app and the reader pane.
  • Making Your App Feel at Home on MacOS: In this chapter, you’ll go deeper on several other Mac-specific features. When you’re done, you’ll have the makings of a world-class Mac app.
  • The Mouse: Use UIHoverGestureRecognizer to show a shadow effect when hovering over a diary entry in the sample app.
  • Barista Training: Menu Bar: In this chapter, you’ll learn all about the menu bar by trimming the default menu bar, as well as adding new items to delete, share and add new diary entries.
  • Barista Training: Toolbar: In this chapter, you’ll learn to customize the toolbar items, including Share, Insert and Print.
  • Barista Training: Touch Bar: In this chapter, you’ll continue to develop your app by adding the toolbar items to the Touch Bar.
  • App Store: In this chapter, you’ll read about the pros and cons of distributing on the Mac App Store, and learn how to go from Xcode all the way to a released app on the App Store.
  • Third-Party Distribution: In this chapter, you’ll learn how to make sure everyone with macOS can run your app, as well as how to improve the installation experience for your potential users.
  • …and much, much more!

Catalyst by Tutorials is 100% complete and available on sale today for the special launch price of $49.99!

4) Combine: Asynchronous Programming with Swift

Combine: Asynchronous Programming with Swift

Combine: Asynchronous Programming with Swift is the best book to master declarative asynchronous programming with Swift using the Combine framework!

The introduction of Combine into the Swift ecosystem now gives you a native way to manage asynchronous events in Swift, meaning you don’t have to rely on third-party reactive frameworks for event-driven systems.

What’s inside Combine: Asynchronous Programming with Swift:

  • Time-Based Operators: A large part of asynchronous programming relating to processing values over time, this chapter goes into the details of performing complex time-based tasks that would be hard to do without Combine.
  • Sequence Operators: When you think about it, Publishers are merely sequences. As such, there are many useful operators that let you target specific elements, or gather information about the sequence as a whole, which you’ll learn about in this chapter.
  • In Practice: Building a Collage App: It’s time to try your new Combine skills in a real project and learn how to make Foundation and UIKit play along with your reactive code.
  • Combine for Networking: This chapter teaches you how to seamlessly integrate network requests in Combine publisher chains and make your networking easier and more resilient.
  • Debugging Combine: Debugging asynchronous code being notoriously harder linear code, Combine helps with a few tools that will greatly help you improve your understanding of the processes at play.
  • Combine Timers: A niche part of your code, timers are always useful to have around and easy to create in Combine, as you’ll learn in this chapter.
  • Key-Value Observing (KVO): This chapter shows you how Key-Value Observing, which was historically the best way to get notified when a value changed, now integrates nicely with Combine publishers.
  • Resources in Combine: Precisely controlling resource usage is a touchy subject, but this chapter will shed light on sharing operators which let you do just that.
  • In Practice: Networking: In this chapter you will work on a networking API that talks in real-time to the Hacker News servers and along the way exercise using multiple operators and publishers in Foundation.
  • …and much, much more!

Combine: Asynchronous Programming with Swift is available now in early access and on sale today for the special launch price of $49.99!

These three books are part of our Advanced iOS Summer Bundle! At just $99, this bundle saves you over 40% on all three of our new books. Get it here.

Updated Books on Sale

We’ve also been busy updating all of our books for Swift 5.1, Xcode 11 and iOS 13. Check out what we’ve updated this year!

5) iOS Test-Driven Development

iOS Test-Driven Development teaches you to write maintainable and sustainable apps by building them with testing in mind or adding tests to already-written apps.

Here’s what’s new in iOS Test-Driven Development:

  • RESTful Networking: You’ll learn how to TDD a RESTful networking client, specifically setting up the networking client, ensure the correct endpoint is called, handle networking errors, valid responses and invalid responses and finally dispatch the results to a response queue.
  • Using the Network Client: You’ll use the previously created network client in your application by updating the ListingsViewController to use the DogPatchClient to actually network.
  • Image Client: You’ll use TDD to create an ImageClient for handling images. You can use that ImageClient anywhere you need it in the app.
  • Legacy Problems: Beginning TDD on a “legacy” project is much different than starting TDD on a new project. For example, the project may have few (if any) unit tests, lack documentation and be slow to build. This chapter will introduce you to strategies for tackling these problems.
  • Dependency Maps: Before you can make a change, you must first understand how the system works and which classes relate to one another. This chapter will give you a tool for doing this: dependency maps.
  • Breaking Up Dependencies: In this chapter, you’ll use the strategies and techniques you learned from the previous chapters to start TDDing changes to the legacy app. To make this possible, however, you’ll have to break existing class dependencies. You’ll learn how to do this in a safe(r) manner in this chapter.
  • Modularizing Dependencies: you’ll continue the work from the last chapter, further breaking MyBiz into modules so you can reuse the login functionality. You’ll learn how to define clean boundaries in the code to create logical units. Through the use of tests, you’ll make sure the new architecture works and the app continues to function.
  • Adding Features to Existing Classes: You won’t always have the time, or it may simply not be possible, to break the dependencies of very large classes. In this chapter, you’ll learn strategies to add functionality to an existing class, while at the same time, avoid modifying them!

iOS Test-Driven Development is 100% complete and available on sale today for the special launch price of $49.99!
