Master Swift Generics: A practical guide to code reuse

Master Swift Generics: A practical guide to code reuse

Generics are a great feature of Swift that allow you to generalize and reuse code in ways that would not be possible otherwise.

They are also a quite advanced feature and become a roadblock for many developers. The iOS SDK uses generic extensively, something that is especially true in SwiftUI.

In this article, I will show why generics exist and how to use them in your apps.

A Practical SwiftUI Kickstart

A Practical SwiftUI Kickstart How to Create Complete iOS App Interfaces

SwiftUI is a revolutionary way to create user interfaces on iOS and other Apple platforms.

It introduces a new declarative syntax that allows you to build user interfaces packed with features quickly.

In this article, I will show you an overview of the SwiftUI features you will need in every iOS app you will ever build.

Model-View-Controller in iOS: A Blueprint for Better Apps

Model View Controller in iOS A Blueprint for Better Apps

Since the introduction of SwiftUI, I have seen many developers write all their code inside views. Unfortunately, the simplicity of the framework seems to encourage a return of many poor practices.

But you do not build robust, maintainable apps by gluing together random pieces of code.

Sure, you can search on Google for specific tasks, copy and paste some code into your project and make it work, somehow.

That works if your app is small and simple. But as soon as you go beyond basic tutorials, you inevitably get serious problems.

That’s why the MVC and MVVM patterns exist. In this article, we will see how they apply to SwiftUI.

Protocol-Oriented Programming: The Best Tool of Expert iOS Developers

Protocol-Oriented Programming: The Best Tool of Expert iOS DevelopersAfter the introduction of protocol extensions in Swift, Apple started pushing protocol-oriented programming.

Even if it was a new paradigm, it quickly got widespread adoption in Swift programming and iOS development. 

This is not a surprise. Protocol-oriented programming is a highly flexible paradigm with many benefits. One of my favorite applications is to create well-structured network requests.

Protocol-oriented programming solves many of the problems of object-oriented programming. Moreover, it works great with Swift’s value types, i.e., structures and enumerations.

For loops in Swift: a Detailed List of the Most Practical Uses

For loops in Swift a Detailed List of the Most Practical Uses

For loops are a fundamental construct of programming, and even more so of making iOS apps. If you want to become an iOS developer, they are a necessary tool you need to have in your toolbox.

But more important than simply understanding how they work, is to know how to use them for the different tasks you will meet in iOS development.

So, the aim of this article is not only to show you how Swift for loops work, but how to use them to solve the most common programming problems.
