Swift Value Types. Structs Vs Classes
- Basic understanding of 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 discuss value & reference types and how they exhibit different behaviour. Reference types are instances of classes (objects) and value types refer to basic data types such as an Int, Double, String or a Struct (copied values stored in memory).
2. We write code in an Xcode Playground to test the behaviour of struct and class singletons. We learn the differences in memory management and explain some architectural principles we might be breaking.
· What is a value type
· What is a reference type
· The behaviour of a struct
· The behaviour of a class
Sample Code Is Always Included and attached to each video. You can download the same project used in each episode of the course.
This Course Is Free
This course is free. We aim to publish as many short courses as we can to help new iOS Developers apply for jobs in iOS and enter a high paying profession. We want those developers to write great apps that are robust, work correctly, and are maintainable. By supplying this information for free we hope we can reach as many people studying in the pandemic as we can.

What Is SwiftUI?
SwiftUI is a newly released UI Framework introduced to iOS. It aims to solve a lot of problems with apps, such as running on all platforms, reducing bugs, improving stability and bringing more developers to iOS - because it's easier to write apps!
Learning SwiftUI is an absolute must for any iOS developer looking to develop a career over the next 5 years.

Our GitHub Account
We made the official Swift documentation searchable. Visit our account on the GitHub website @matthewpharding for more details.
Our Udemy Courses
Our goal is to provide direction to those who want to learn Swift in order to better their lifestyle or livelihood. I can fully recommend iOS and Swift as fantastic opportunities to live a wealthy, healthy and happy life, working fully remote as a computer programmer.
Our online courses are designed to learn Swift fast in as little time as possible. We condense as much as we can also providing over a decades worth of knowledge and tips within every video.
We are new to Udemy courses and are working hard to deliver great content. Please show us your support and let us know how we can do better.
Our Teaching Style
We have taken the official Swift documentation and translated the official programming guide into Xcode playgrounds. We then simplified the content creating a guided tour of the Swift programming language with a course project. Inside each one of our videos you will find the attached sample code to interact with every given example. This is a hands on course that focusses on writing code first and watching videos second. This provides a full customer experience as more stimuli have been catered for. By providing both written interactive coding examples alongside a guided video explanation learning can be efficient as possible, significantly reducing the time required to increase knowledge.
Udemy kindly offers a refund in full for any unhappy customers - so why not try us?
Some Coding Tips
We use many technical terms within the industry and perhaps some of the most frequent are ‘design patterns’ and ‘architecture’. You can think of design patterns as a type of blue print used to structure a certain type of communication between a cluster of objects. As an example we may chose to use the Factory pattern to write a class that produces cars to a fixed specification already configured. This term can then be used in conversations to describe the behaviour and type of structure you have used to construct a certain feature or area of the codebase.
Architecture is essentially very similar and is used to describe the entire infrastructure of every component within the system itself. Design patterns are used to design and build the architecture and a solid system cannot built without this type of order. Perhaps when we think abut this term architecture we should think of the term ‘structured code’ and remember the importance of structure communication between files.
How To Become An iOS Developer
Most companies that offer iOS developer jobs simply need to maintain an existing Swift system that has previoiusly been put in place. Creating the architecture and thinking about performance can be difficult and may require some expert knowledge, but they are not the needs of most companies. In fact, if you are interested in maintaining an existing system then the technology industry will be a huge market place in which to advertise your skills.
With the interest of both parties in mind (the business and the employee) having great Swift knowledge and being able to write safe code will be the biggest focus, which is great news.
This means, all you need to do is learn Swift.
Why Learn Swift
To become an iOS developer with a great salary who can work anywhere in the world using only a laptop and an internet connection.
By studying the language all of the other pieces of the puzzle will fall into place. With a clear grasp of the Swift programming language it will be much easier to apply for jobs and to pass each test they provide. The rest will be provided to you as you learn whats required within that role for that specific company.
Our Goal / Motivation
We are trying to consolidate more than a decades commercial experience combined with the official Swift documentation into short online courses (created for fast learning), so that our students can live happier and wealthier lives - Swift engineers are well-paid and can work anywhere in the world.
Why not think about becoming an iOS developer making apps for Apple software.
We made the official Swift documentation searchable and made available on the GitHub website. Our courses also condense the official Swift programming guide into short digestible and editable coding examples and we aim to enhance the lives of each of our students.
A big warm hug and thank you to all of our students. Repetition is the key. Just keep writing code each day and then the only remaining factor is time. You can do it, I promise.
