for the while loop eg. why is it that if index ++ is written on the same line as println, then the code will not work

Is it becaues the syntax requirement is such that each statement has to be written on a new line?

Easy, each code statement has to start on a new line. You can write multiple statements on one line, seperated by a ; but I wouldn't recommend that as your code will get unreadable over time.

This is what I made my while statement look like, and works perfectly, since index is being incremented AFTER 'println()' is executed since I am incrementing as a suffix:

while index < todo.count {

println(todo[index++])

}
