I've not words to describe how thankful I am for your extremely clear explanation!

[SaedAlavinia]

I only had 5 minutes to spare and came here to learn about explicit declaration. The awesomeness of the video had me till the end!

Love the explanation of functions as params and return types. Thanks, almighty Skip!

[jensBendig]

Thank you very much for the explanation about the internal and external parameter. This is a feature I was always missing in languages that do not use headers. With headers, like in C++, we easily could name the external params in the header and the internal ones in the bodies. Now I have this (important) distinction back! Yipieh!

You know what?! You are absolutely awesome! Very clear, straight forward lessons. Thank you!

That's super awesome! 2 hours of reading cut short to half an hour video and yet learned more :)

[George-oruv]

This is a very well done video to describe Swift Functions.

How we define the constraint on function's arguments ??
e.g:
we have a function :
 func   xyz(str: [String] ){  }
 
and Constraints :
str will contain between 2 and 10 elements.
 Each element of str will contain between 1 to 5 characters
 Each element of str will consist of only decimal digits (0 - 9)

I'm sorry man I just had to say I laughed so hard when you tell us to 'get ready' at the start. I wasn't sure how to get ready so I just pulled a face and started laughing. Thanks for the vids they are really good.

Thanks Skip!, even though I am still 12 years old and too young to learn some coding. I am learning a lot from you.

great vids..so annoying that I'm using swift 3 and now a few things have changed..input parameters can't be var,
func blah(#input: String) dosent make it the input external name anymore. ++ == are going. hard to keep up when your new to swift and all the tuts are swift 2.0. but I'm loving the challenge of learning this code!!!

Awesome tutorial, just started migrating to Swift from Objective-C.
I have question regarding the 'inout' thing, isn't it as if we are passing parameter by reference instead of value? or is it something different?

Thank you, I am really entertained by your tutorials. Very well explained. 

[ruiguo]

Thanks for making these tutorials video

[BRBallin]

Good tutorials. I am trying to make user applicable programs and so far your tutorial hasn't covered stuff like that u have in applications like images and buttons. 

[HikikomoriDev]

"So get ready." ..This is it. This is it... The truth xD

[dexmax]

So why would you do
#number: Int  instead of number: Int

and also could you please explain to me what this all means and why you would do that?
 
func buildIncrementor () -> () -> Int{

}


Let me get this straight please.

The code in the parenthesis is the arguments and the -> Int means that the return value will be an integer? 
Thanks! Your vids are awesome! I got the developers license so I could program in Swift.
