SwiftUI And MVVM. Adding MVVM into a sample project. – Free Udemy Courses

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 ios free



(pronounced “iOS Be Free”).

In This Course

1.



This course is free. I hope that it helps to continue the discussions on architecture with the new realize of SwiftUI, which is using a new type of programming paradigm (known as Reactive Programming). We discuss MVVM and architectural design principles such as layered 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 that 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 on top 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 with 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 type isn’t reduced to having just 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.

Learning Objectives

• Quickly add MVVM to an existing project
• Understand the architecture of the MVVM design pattern
• To evaluate someone else’s project, code, and code-structure

Sample Code

Sample Code Is Always Included and attached to each video. You can download the same project used in each episode of the course.

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.

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 the pandemic as we can.
