Add MVVM to a SwiftUI sample project. Learn Layered Architecture and how to examine projects for Code Review. – Free Course
- Only basic experience required
* LEARN FROM ONE OF THE WORLDS FIRST IOS DEVELOPERS *
================ 13 years in iOS ====================
1. This course is free. I hope that it helps to continue the discussions on architecture with the new realise of SwiftUI, which is using a new type of programming paradigm (known as the Reactive Programming). We discuss MVVM and awesome architecture.
2. We introduce the MVVM architectural design pattern into a sample project using a really simple approach that only takes a few minutes.
3. We focus on what’s known as having a layered architecture. A layered architecture is when you separate the responsibilities into layers which sit on top of each other. As an example, we could have an application with 3 layers. Layer 1 (the lowest layer) could be the networking layer, layer 2 would sit ontop consisting of our business logic and ViewModels and finally layer 3 (the top layer) would only display UI and is known as the presentation layer. The layers communicate between each other but the information passes between layers and so Layer 1 would not communicate to Layer 3 directly without passing the communication to Layer 2.
The alternative to a layered architecture is known as ‘spaghetti code’, which you may be familiar with. Spaghetti code doesn’t have much of a structure and individual classes seem to talk to each other on an individual to individual basis. Also, each file typically isn’t reduced to use only one Single Responsibility (my advice: don’t write a class that does more than one thing!). With spaghetti code the classes and structs tend to do a lot of things.
Tip: Avoid writing spaghetti code because it is untidy, harder to read, lacks structure and ultimately makes it more difficult (and more expensive) to maintain.
Free Videos & Courses
These courses are free. I hope you enjoy them. I keep the course short. 1 hour is pretty good to learn some new tricks. Architecture is the foundation of engineering and I hope I can encourage everyone to learn more about it. I will help out where I can and share as often as possible.
Check out my Instructor profile (just briefly) and glance over it to know about my experience. After 13 years on iOS I would like to start giving back and supporting my fellow iOS developers.
Apple has given me a great career and if possible I would like to contribute to this incredibly talented and highly skilled community.
Whats a Mini Course
A course that is roughly 1 hour long and with only a handful of videos so that it is easily completable in a day! So many people have asked for short little courses and I completely understand why users / developers would want something they can finish in an hour. I hope this helps.
