iOS Swift Basics (retired) Control Flow For-In Loop

for-in format

Do you have to put the for-in function on multiple lines?

at 2:16 he spaces the function over 3 lines, and it seems like this is the only way for it to work whenever I do it myself. He does not mention this being a requirement.

So I am wondering if my computer is just acting up, or this is the way you have to set up For-In functions.

Hi Don,

Whitespace is not important to Swift, so the three lines are not a requirement. I wouldn't recommend it, but you could write a for-in loop like this if you really wanted to:

hardToRead.swift 
for item in todo{println(item)}

I doubt your computer is acting up - it's probably something else that's causing your problem.

That said, it's a very good idea, and is considered a best practice to indent your code for easier reading. Amit's formatting is what you should follow for readability.

Best,

-Greg

Thank you Greg! I dont know what's going on with it.
Now that I go in and take away the indents, after the fact, it works. Probably just my dumb luck.
