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.

This is a excellent book. The reason I give 1 less star them 5 is it’s doesn’t have any thing new to offer to already experienced developer.

Kim K Feb 13, 2023

The organization of topics was quite good, as well as explanations, descriptions, and examples illustrating the concepts of Swift. There are nice chapters on extralingual topics such as design patterns and protocal-oriented programming.However, I had many issues with the text:* It is littered with errors, both in the text and in the code. For example the phrase "... throws an error" was used (which is a runtime event), where "... causes a compile-time error" should have been used. And a typical spelling error: "Warth" appears where "Earth" should be. The pages are filled with these kinds of errors.* The index is *very* short, compared to other language books I have. In a reference book, a good index is critical.* In the String section there was no coverage of the Substring struct, which deserves discussion because it does not occur in some other languages.* Example code blocks have comments describing the results. Then paragraphically, the *exact* same thing is said. It is redundant (and painful).* Oddities abound. For example, for enums, he first says it is preferred to begin enum values with lowercase. Then he proceeds to define most examples with uppercase!?* There are fullscreen images of the Xcode editor to show code and run time results, but the font is too small to read!! This occurs frequently in chapter 1, but thankfully less so in the rest of the book. Actually, Swift is available on Linux and Windows, so I would prefer a platform-neutral book, using comments and text to explain the concepts, instead of utilizing the Apple-only Xcode tool.* There are so many of the "next we'll look at xxx yyy", followed immediately with a section title of "Xxx Yyyy". Some may like that, but to me it is just noise.This could be a *great* book, if efforts are made to improve these things.

Great reference book, but definitely not for individuals just getting started in programming.

This is a clear, concise and easily readable presentation of the basics of Swift, certainly usable by anyone familiar with the basics of modern computer-languages. (It is, after all, a description of Swift, not an introductory CS course.)The only problem is that the index (of only 8 pages) is useless for finding anything other than the most rudimentary items. For example, there is no entry for the key word "mutating." This is a situation I've found to be common with books published by "Packt>".Complete answers have to be done with Internet searches, or (as is perhaps the goal of such under-documentation) by subscribing to packtpub.com.

Looking for a book underwriting the more intermediate and advanced approaches to programming with Swift, I was initially concerned with the beginner-level difficulty of first few chapters of actual Programming content. However, I was even surprised the odd piece of Swift functionality in these first chapters that had not as yet come across.My concerns weren’t long-lived. The book, although not in great depth, covers a large variety of programming paradigms and concepts and how they are approached with, Swift 5. Overall, I’m glad I bought this book.
