Udemy Gratis: Swift Singletons | La diferencia al usar clases y estructuras



Created by iOSBFree. Understanding the differences between class and struct singletons in Swift iOS.

Learn From One Of The 1st iOS Developers In The World

Our instructor Matt, has 13 years of experience in iOS and created the world’s first iPhone, iPad and Apple Watch apps. Now, he dedicates his time to recording courses for iOSBFree (pronounced «iOS Be Free»).


In This Course

1. We create two singletons in a Playground.

2. Each singleton is created using either a struct or a class.

3. We examine the advantages and disadvantages of each approach


Learning Objectives

· What is a singleton

· The behaviour of a struct singleton

· The behaviour of a class singleton


The Goal Of A Singleton

Together, we’ll examine the behaviour of two different approaches when creating singletons. The more classic approach is to create each singleton using a class due to its memory management – when the singleton is created it will exist in only one area of memory and never be duplicated. However, the opposite can be true when dealing with struct singletons.


Our Recommendation

Our recommendation would be to always use a class singleton due to the principle of a singleton itself, which is to maintain only one of its kind within the system. One manager handles the inflow and outflow of certain behaviour. If we want to ensure that we don’t duplicate our singleton, we should stay away from struct value types that use such behaviour by default.


Sample Code
