Swift and iOS Development Best Practices
The first step to making iOS apps is learning Swift.
But learning a new programming language can be daunting if you approach it for the first time.
Nonetheless, if you follow the right path, learning Swift can be fun and rewarding. Many developers worldwide use Swift because they like to build well-crafted programs.
In this article, I show you the right path to learning Swift.
I won’t only cover the how, but I will also explain why each piece is essential to build the whole puzzle.
Arrays are the most commonly used data type in Swift and other programming languages. You will often use arrays to organize your app’s data as they are the most versatile data structure.
This article will explore the most common features of arrays in Swift.
The easiest way to install Xcode is using the Mac App Store.
But that’s not necessarily the best way.
While you can install Xcode with a simple click, using the Mac App Store is very slow, and the download might hang indefinitely or return cryptic errors.
The best alternative way to install Xcode is to download it from Apple’s website. If you are proficient enough, using the command line is the fastest.
In this article, we will look at all of the alternative ways to install Xcode, how to speed up the process, and how to resolve disk space problems. We’ll also look at the Windows alternative to Xcode.
The ternary operator is a conditional operator that you can use to write complex conditions using just one line of code. It is straightforward to use and powerful.
In this article, I will highlight the most common use cases of the ternary operator in Swift. I will also review the advantages and disadvantages of writing conditions using the ternary operator instead of if-else statements.
Switch statements compare specific values against different cases and execute the block of code associated with the first matching case. You can achieve the same result using an if statement with multiple else clauses, but switch statements are easier to read and understand at a glance.
This article covers the most common use cases of switch statements. There are other, more advanced features of switch statements that I will talk about in future articles.
To be able to do anything interesting, a Swift program needs to take decisions based on whether some condition is true or not. This is done through conditionals.
Swift has several conditionals. The most common one is the if statement, which we will cover in this article.
Learning how to program is not an easy task. But it is straightforward to get started with it by following a very simple Swift tutorial.
The very first program everyone writes is called Hello World. It teaches you the basics of creating and running a program in any language.
