Description

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 recording courses for iOSBFree (pronounced "iOS Be Free").


In This Course

1. We examine two Xcode projects: From Apple and also online

2. We search for code enhancements

3. We lookout for code smells (code that looks like trouble in some way)

4. Try to spot code that breaks layered architecture design principles


Learning Objectives

· How to review an Xcode project

· How to look for code smells

· How to preserve layered architecture

· How to check the imported frameworks for architectural clues

· Why we don't use FatalError() in commercial projects

· Why we don't force unwrap optionals in commercial projects


Layered Architecture vs Spaghetti Code

Together, we’ll investigate two sample projects looking to enhance the code whilst searching for any areas that could break a layered architecture design. When constructing a solution using a layered tier system is a must in terms of design as it provides order and structure. And remember that without this kind of infrastructure our tools would consist of an unordered collection of files all communicating with each other in a very difficult manner to follow or understand. i.e. like a ball of tangled spaghetti.


Sample Code

Sample Code Is Always Included and attached to each video. You can download the exact 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 and amazing apps that are robust, work correctly and are also maintainable too. By supplying this information for free we hope we can reach as many people studying in the pandemic as we can.

Free Courses

I provide free step-by-step mini courses (1 hour) to learn SwiftUI whilst also teaching architecture.

I record these courses to provide a little direction with how we structure our SwiftUI projects. There are many amazing SwiftUI tutorials and sample code available on YouTube, Udemy and the Apple developer portal, but they mostly miss some key points in basic architecture. My aim is to help teach students on Udemy some best practices, how to analyse projects, how to analyse architecture


- Learn SwiftUI

- Layered Architecture

- Code Review techniques

- How to examine code

- Memory management

- MVVM



How To Write High Quality Code

My aim is to help teach students on Udemy some best practices, how to analyse projects, how to analyse architecture and how to write maintainable apps - your career will benefit from it!


- Layered Architecture - (Networking, Data and Presentation Layers)

- KISS - always write simple solutions

- Single Responsibility - types should only do one thing

- Readability - code should be understandable by juniors, mid and senior developers

- Maintenance - ensure code is not constantly re-written or edited

- Never connect systems that shouldn’t be connected

- Cover every error scenario - don’t think of errors as an edge case

- Edge cases are equally as important as success cases

- Never create an instance of FatalError()



What Is High Quality Code?

Code that is readable by everyone = all levels of developers

Solutions that are simple in nature = less moving parts = less potential problems



SwiftUI Is The Future

Prepare for the future and learn SwiftUI. Apps are buggy, crash too often and developers are having to constantly re-write code. Apple are focussing on more stability for the future. SwiftUI together with the Swift language are great tools to write simple and safe solutions. SwiftUI also uses the Reactive Programming paradigm to create solutions.

It’s time to learn SwiftUI.



Great Projects = Understanding Architecture

You wouldn’t trust a brick layer to build a sky scraper and perhaps you shouldn’t trust someone who only writes code to build an app. We need more. We need to understand architecture. We are engineers constructing our solutions using thought and structure - we call this architecture.


- Layered Architecture

- Never connect systems that shouldn’t be connected

- Single Responsibility

- KISS
