Coding Review - SwiftUI example with Best Practices - Tips and Tricks - Core Data Preview & Canvas

In this video I am going to review another SwiftUI project. I will discuss best practices for SwiftUI and the Swift programming language. We will see how to use Core Data CRUD operations and implement he preview provider to see the canvas.

👉 The original tutorial from Kavsoft is SwiftUI 2.0 Core Data Best Practices - SwiftUI 2.0 Core Data CRUD Operations - Tasks App

You can find the documented project code at

Overview
00:00 Intro
01:18 Dependency injection with Core Data - use for preview / canvas
05:26 flexible frames - how to expand view to full width
20:08 Button Style and sharing view modifiers with custom view modifiers
28:43 Combine in action: sink and subscriptions
33:17 fixing a bug: clean up when view disappears with onDisappear
34:32 Core Data best practices: model extensions to add syntactic sugar
40:06 Swift language: Enum and naming conventions
48:42 Wrap up

This is so great! A lot other channels, mostly non-development, typically critique or discuss other channels' videos. You are the first one I discover doing that for another channels' SwiftUI video and I love it. Learning so much from this and I think this is also what the greater development community should be about: helping one another. I also love your thourough explanations! Thank you

there is nothing better than some good refactoring. Subscribed!

This was a fantastic code review. I’m going to share this with my team to improve PR reviews. Looking forward to more

[jeff.fredrickson]

Thanks for this code review! As a software engineer new to Swift and SwiftUI, I appreciated learning the real best practices such as Combine, flexible frames, and view modifiers. I hope to see more like this!

[yusefnathanson]

Thank you! This kind of video is exactly what I need to advance. Please consider making more refactoring / best practices videos.

[alexmedvedovski]

Nice code cleanup. I also really enjoyed the tips & tricks that you showed.

[gabrielros]

This is really great concept. There is a lot to learn from this. Please keep adding more video with "Code Review" concept.

[GaryLutchansky]

Wonderful! The technique you use for this video helps my comprehension of what to do and why to do it. Thank you very much!

[lincolndickerson]

Great job. There are ao many great tips here. Thank you! More code reviews would be awesome. There are so many “ Simple” examples that bypass good practices like using enums instead of string compares. The core data helper is fantastic.

Thanks for this. Again, a great video lesson. It’s very useful to see an excellent developer do a code review like this. I learnt lots. Thanks.

Love this kind of video. Very nice channel and very good videos to get better in Swift/SwiftUI

[juanparodriguez]

Beautiful. Great code review. I have learned a lot with you.

[encodedlife]

Enjoyed it and looking forward to more of your videos.

[bobweiram]

This is an awesome video. You should do more of code reviews and refactoring. It's an great way to introduce new ways to improve code quality resorting to non-real world examples..

[emresancaktaroglu]

I want my SwiftIUI projects reviewed by you very much. I will send my project as soon as I finished.

[peterplass]

Hallo und Danke für dieses Tutorial.
Ich habe versucht, alles exakt so nachzuvollziehen. Und: es klappt! Vielen Dank!

Perfeect! Someone actually explaining what the code does, thankyou!! :)

[rillieux]

Thank you the video. Do you have your own GitHub repo with your completed code?

[scribblingink]

Thank you for this! You’re the first person I found who even addresses the new auto generated code in core data. I think it’s about 50% more clear now! 😅 Perhaps you could reach out to the original YouTuber and give them tips for updating the tutorial, or if you have the time and desire, make a quick tutorial walking through that auto-generated core data code. Either way thank you again for this video! It’s a great example of a respectful code review. 😊

Really awesome coding review, I found that when delete a task, context is not saved, should this one be another area need a fix?
