Wow, Chris, this series is fantastic! You've just cleared up a mess of information that I've been looking at in a few different books--and so succinctly. I really appreciate all your efforts on teaching Swift!

[alfredogonzalezgalicia]

Yeah Chris, your classes are fantástics and your clean pronunciation helps me to understand each word. Greetings from Mexico.

[programmeromkarpawar]

Hey, Thanks Chris so much i was searching to learn swift all other videos are not informative
I really appreciate your work towards teaching swift without cost

[CodeWithChris]

QOTD ⚡Does subclassing make sense to you? Let me know!

[DukeDuke]

This is so great! I had such a hard time understanding class and subclasses. You made it easy to understand by going about it step by step.. Thanks a bunch!

[udayjain]

Hey Chris I have started learning Swift now. You are too good with your concepts and information. Thanks for that.

[nococo]

Thank you so much for your concise and clear tutorials – all the other resources I found on the net are very hard to get into.

[caseanonymous]

You're the best, all the tutorials are clear, detailed and easy to understand!

[emilazizov]

Definitely one of the best lessons, many thanks, so clear and helpful

[amitbt]

Your tutorials are so clear.
Thank you Chris!

[Blankslate]

Great video, everything was well explained!

If anyone is having difficulties conceptualizing classes and subclasses I think looking at ERD database models can be helpful. Databases often use very practical, and intuitive, examples that translate easily to object oriented programming. (In database terms this is called specialization)

[JoeDoe]

Thank you it’s all coming together. I spent a lot of time piddling with Swift and getting nowhere.

[RashaadFontenot]

That was amazing. Thank you. I totally understand classes now.

[sweld]

I appreciate the work you do Chris, this was a great explanation!

[leningradka]

Definitely this tutorial is one of the best in my opinion. Great job, Chris! Thanks for the high level of quality of information about Swift. Keep doing it :^]

[szymondalagopisz]

Oh boy, it's getting serious... Love it!!!

[JamesEtallaz]

Great video! Classes look really powerful. I still have 2 questions:
-Can I write to navigate in class hierarchy?
-Or, is there a keyword to go directly to top/highest super class?

[tomcyclope]

From the moment you wrote override, it began to be really hard which is funny, I like it. basically there are 2 key word for this lesson its override and super that I didn't know.
I have a question : how many video like this Tutorial for beginners have you planned (in the first video, you wrote 12 with dictionary, array) ? I started code with these videos series which is really perfect and before that, I was on swift playground on iPad (the level between playground and your video is different).

ps : after these video series, I plan to focus on your other serie : make an app for beginner.

[TechBoxNorth]

Any plans on making a similar series about making apps with flutter?

[microcuts]

Hey Chris! I'm wondering why you used "salary += x" if you didn't use it? Thank you for these lessons!
