This appears everytime...
let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
var index = 0
while index < numbers.count {
println(numbers[index]) }

Think about what your code is doing:
- The program hits the
whileloop, checks to see ifindex(which is 0) is less thannumbers.count(which is 10) - It is, so it prints
numbers[0](which is 1), and goes back to the top. - It checks to see if
index(still 0!) is less thannumbers.count(still 10), and prints again.
...
This will go on forever.
You need one more line inside your while loop. Something like index = index+1 or if you're fancy, index++. This way when the loop runs a second time, index will be 1, then 2, and so on.
This is something you have to be careful with. If you get stuck in an infinite loop outside of the safety of Workspaces, your program will crash.
Happy programming!
