What you will learn

Build a MVVM architecture app with confidence

Unit Test (increase robustness in business logic)

UI Test (preserve the integrity of business flows)

Snapshot Test (preserve the integrity of views from unwarranted modification)

Why take this course?

Welcome to the iOS & Swift - MVVM, Combine, SnapKit, Snapshot/UI/Unit Tests course!

In this course, I share my learnings as a professional iOS developer with 6 years experience on the topics that are relevant to the industry today. The materials I've prepared are knowledge that I wish I knew as a 3 year old developer struggling with concepts like:

Protocol orientated programming
Reactive programming
MVVM architecture (why not MVC?)
Coding views programatically with SnapKit (without Storyboards)
Writing unit tests
Writing Snapshot tests
Writing UI tests

In this course, I explain and implement the above-mentioned concepts through a simple Tip Calculator application step by step. I start off by building the UI, then the ViewModel which house the business logic and finally implement the various tests to ensure that we preserve the integrity of our code.

These concepts are extremely important to a senior iOS developer because of the expectations and responsibilities placed on you by the various stakeholders in your company. As such, you need the SKILLS to

Debug issues quickly
Upkeep code coverage and testability to ensure CI passes
Set an example to junior members in your team with high quality coding standards
Avoid on-call nightmares (paper duty ringing non-stop)
Fix and stop adding new tech debts
Maintain your sanity as your app grows over time

So this course targets developers who have been working for around 3 years who want to get to the next level. I am confident you will grow after completing this course.

Good course for intermediate level. I improved my skills for MVVM architecture with Combine, programmatic views and it was a nice introduction to testing.

I like the content of the course, but the instructor speaks and types very quickly, which makes it hard to keep up.

Helpful course. Good explanation of Unit and UI testing. Step-by-step guide on how to build the UI using code and SnapKit. And how to use the MVVM design pattern and the Combine framework. Thank you.

Great course. It would have been even better if you went into more details for Combine, but great content.

This course is absolutely amazing! I was shocked by how you can easily set layouts with snapkits and use combine to bind all datas together. Getting into Unit testings were definitely very interesting! Would recommend to others as well. Thanks for the great course Kelvin!

This course is just awesome, this course can also be considered if somebody is new to Swift and MVVM as it goes through all the aspects of Swift and MVVM. You learn two new basic libraries one is SnapKit (UI Dev) and the other is Combine (Reactive Programming - MVVM). An end to end Swift crash course as it includes Unit Testing as well. Many thanks Kelvin for bringing up this course.

This course is pretty good if you want to grasp the idea of how to use Combine with MVVM and UIKIT. The Unit, UI and Snapshot tests are also explained pretty well.
