Mastering Swift 5.3

Swift Documentation and Installing Swift

I spent a lot of my career working as a Linux System Administrator and Network Security Administrator. These positions required me to compile and install packages from source. There are a lot of advantages to building packages from source rather than downloading prebuilt binaries. The biggest advantage, in my opinion, is that you can get the latest version without having to wait for someone else to build it. This allows me to patch my systems with the latest security updates without delay. With Swift, we are also able to download the latest code and compile ourselves without having to wait for someone else to build it.

In this chapter, you will learn:

About the swift.org website and what it offers
How to find the latest documentation on Swift
Ways to install Swift
How to build Swift from source with its full toolchain and package manager

In the previous chapter, we mentioned that Apple has released...

Using the Swift package manager

There is a lot that you can do with the package manager that makes it a necessity for creating complex applications on the Linux platform. It helps with adding dependencies to projects and enables us to break our code up into multiple files and create library projects. You can use the package manager on the Mac platform as well, but I do find it easier to use Xcode.

For the examples in this book, we will not need to add dependencies or use multiple files. Let's see how we can simply build and run an executable project in the package manager so you can use it to run the examples from this book if you would like. Keep in mind you are able to use the package manager on the Apple platform as well. When the package manager created main.swift in the Sources/test/ directory it added the following code to it:

print("Hello, world!")

This code gives us the basic Hello World application. You can replace this code with examples from...

Using the Swift compiler

The Swift compiler is the basic utility to build Swift code and it is used by the package manager, Xcode, and any other utility that builds Swift code into executables. We can also call it ourselves. To see how to call it ourselves, create a file named hello.swift and add the print("Hello, world!") code to it as shown with the following code:

echo `print("Hello, world!")` >> hello.swift

Now we can compile this code with the following command, which calls the Swift compiler:

swiftc hello.swift

Finally we can execute the newly created application like we would any other executable:

./hello

And we will be greeted with our Hello, world! message.

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

I purchased the previous version of this book with a humble bundle a while back so this review will take a moment to focus on whats new in the 6th ed:A chapter about Swift documentation / installing swift was inserted and is now chapter 2. This will help you understand how to work with swift on Linux if you dont have a Mac, HOWEVER sticking to XCode on Mac is the optimal experience.Also new in this verson: error handling gets an added section on multi pattern catch clauses which is new to swift 5.3 and a good addition by the author.Synthesized Comparable conformance for enumerations is new to 5.3 and is also briefly covered in this book.A new chapter on Custom Operators is in this edition. I feel like this chapter is geared toward really experienced developers because it was a bit advanced for where I am in my journey.On the book itself. You dont really need much if any pre-existing knowledge on the topic before you start with this. The book has a chapter on almost every topic ranging from variables, collection types, control flow, to functions and more. The book takes time to explain differences between swift and other languages (such as semi-colons or assignment operators) so that is helpful if you are coming from that background. Towards the end he provides a style/formatting guide which will help you keep your code looking professional when its reviewed by potential employers. The design patterns chapter is cool but every employer has their own design pattern so dont waste your time memorizing these, a general understanding is more than enough.As a final note I would like to say this book is really good at teaching you the concepts of Swift as it stands in 5.3, with example code in the book done in playgrounds. After this book I suggest following along with app building tutorials on youtube to help you build your practical skillset and show you how to apply the really great concepts you get from this book. It can be a little dry reading at times but its straight to the point and I highly recommend reading this if youre trying to really get a grip on the language.

"Mastering Swift" has been my to go resource for Swift from its First Edition. The brand new Sixth Edition contains all the relevant updates for Swift 5.3, which allows iOS developers to easily keep up with the language evolution. My favorite chapters are "Concurrency and Parallelism in Swift", which focuses on GCD, and "Adopting Design Patterns in Swift".Definitely a great addition to any programming books collection!

Richard Albury Dec 13, 2020

This book is a pleasant surprise. I breezed through the book in a week, and despite a few years of Objective-C and Swift experience, I still learned a few things.It does a great job of hitting the important aspects of the language while also providing good context, so it’s not just a collection of dry pedagogical exercises. The chapter on swift.org and building Swift is a great introduction to one of Swift’s hidden strengths: an enthusiastic and diverse community of people who care about this open, developer-driven language and the platforms it runs on.I also have to call out the chapter on closures: it’s one of the better introductions to a topic a lot of beginning Swift developers struggle with. The chapter on concurrency deserves mention as well: these two topics are fundamental to master, and the book does an exceptional job with them.Finally, the ending chapter on design patterns provides a good grounding in an advanced topic.Highly recommended. If you had to buy a single book on Swift, this would be it.

Just Me Dec 07, 2020

I have purchased a copy of almost all of the Mastering Swift books because I find them incredibly informative. The author does a great job of teaching Swift while also covering the most important new features of the language. While the first few chapters are geared towards someone first learning the language, the later chapters are a must read for anyone that wants to master the Swift Language. From Protocol Oriented Programming techniques and Copy-on-Write to Concurrency and Generics, this book covers almost all of the advanced topicsWhen I first received my copy of this book, I went right to the Advanced Operators chapters which is one of the two new chapters added in this revision. This is one of the few books that cover details like the Bitwise operators and custom operators. This chapter is a great addition to the book.Just like previous revisions of this book, I consider this a most read for beginners to the Swift Language and also for experience developers that want to take their knowledge to the next level.
