3. How to accept functions as parameters: This video

Tip I learned today after some searching. When the auto complete menu is open hit the "return" key on your keyboard twice to automatically convert to trailing closure syntax! Saves so much time when you have a function that accepts multiple closures!

Awesome !! This is super helpful . I struggle with closures a lot ! :)

It’s clear now. The last example helped me to understand how things are basically flowing.

Fully understood everything. However, why on the second example we didn't used "using". I modified the first example removing the using and still works. Any reason on why and when use "using"?

When I run the function:

func generateNumber() -> Int {
Int.random(in: 1...20)
}

let newRolls = makeArray(size: 50, using: generateNumber)
print(newRolls)

I get an error saying Cannot find 'makeArray' in scope. Has Swift made some kind of update to variable declarations after this video was published?

I work in cyber security, and today was the first day that the word 'hacking' in 'hacking with SwiftUI' really clicked. I got a similar feeling as when discovering a vulnerability during a security assessment. It's really just a matter of figuring out how stuff works and make the code do things you want it to. Loved this course.

We don't have to use the word "using" here.

hi paul. remember how your dad sat us down and told us the path we were heading on would make us jail birds?
and then we made a life choice, with you on swift and me on java.

look at you. how as swift been treating you these 19.3 years? I bet you choose my direct, and did java and her beans the way i did.
at leaste we are not jail birds, thanks to your dads words.
