ABOUT ME

Hi I’m Chris! I’m dedicated to teaching fundamentals about how to make an app. This is important if you’re trying to land an iOS job, be a freelancer, increase or start a business with an app idea. On the site, you'll find a ton of free resources and tutorials to aid you on your journey to learn iOS development. Many people have successfully picked up Swift 4, Xcode 9 and app building from my course and materials!

Here's just a sample of the success stories my students have sent in:

This series is awesome! I already know C++ and Java, but skimming this video along with Chris' explanations helps me learn the syntax for Swift 3.1 faster. Subbed.

i can't believe how easy to understand the basics of swift 3 !!

[abhishekdadwal]

awesome chris! You have made it hell easy to understand for newbies ... thanks for the efforts

[krishanmalhotra]

How do i accept an integer value from the user?
By the way great teaching methodology

[litrich]

Hi Chris, I was curious how you would be able to print the results of the for-in statement one by one. A good example I believe would be - when you level up a character its total damage increases by 2 each level. How would we print or insert that data?

[hurasane]

great series I know java and c# but swift is similar which is cool but how do you control the iterator in the for in loop for example lets say you wanted it to subtract instead of add would you have to put 1...-5?. I have never heard of a for in loop until today. Its amazing how swift knows what your implicit variables are but wont that get confusing as a code base grows maybe its just me and im used to explicity setting variables to types.

[hextaniumfranklin]

So, Chris, we talked before yes, but what do the {curly braces} mean?

[RadenSoCal]

This is still freaking tough to learn, is there an easier way to understand this? i can repeat this over and over but mayn lol this is a gift but thank you

[trentkelly]

What is the significance of using the word "index"?

[FewMinuteProgramming]

Darn, swift looks so interesting. I wish I could develop with it with windows. Guess I got to save up.

[joshuachavarria]

Hey chris I’m watching this video and when typing in my “sum+= index” i get a pop up that says it cannot concert value of type (unsafe pointer ) could you help me explain why I get this pop up and how I can fix it if it’s not too much of a hassle? Thanks chris love the videos !

[vokadekaestheticssalon]

Hey Chris! Can't really understand why you moved the var sum and print("") out of the loop in order for the numbers to add up? Like why does it not work inside the loop?
THANKS

[MartinJurus]

Great ! I have one question:

Why is it 15 in the end ? sum is 0 and index is 1 to 5. Then, in the loop, you declare that sum is actualy sum + index, which means 0 + 1 to 5, which is... 5 ? And if we repeat (or loop) that 5 times, we would get 25, no ?

Little bit confused student

[mpgmafia]

Hello at 9:18 how is the print out 15? Thanks in Advance Guys!

[geangarcia]

"immutable value 'index' was never used; consider replacing with '_' or removing it" --- What does that mean?
