Do not understand the question

Quick reply - Thx Lucas, it is much appreciated. Currently I'm working the late shift, but I will look at this first thing tomorrow morning and I will let you know.

Thanks!

Thank you Lucas! I got the first task correct by substituting the sum for the counter variable.

However, for task 2, I am not sure what the syntax should look like; I did take a look at the example given, but the word "newValue" throws me off. Is the example close to what the example should look like?

Thank you once more Lucas

Hi Michael, glad that I could help with the first task! Let's see what we can do about the second!

Without giving the answer explicitly, I'll explain the concept, using which iteration the loop is on to reference an array index, as best I can in code.

The first bit is that we now have a number that will grow with each iteration of the loop, but won't give us an index out of bounds error, since we stop the loop if counter is the same as the number of elements in the array. This is a rather common convention with loops, and it's quite useful! For this example, we're using it to call up the index of an array, so the general syntax of this would look like the following:

let anArray = [1,1,2,3,5,8,13,21] // Just a dummy array of Fibonacci numbers 
var counter = 0                       // Our good friend counter
var sum = 0                             // The sum where the final value will go

while counter < anArray.count {  // Makes sure the loop will stop before an
                                 // index error rears its ugly head

    sum += anArray[counter]        // Adds value of the current index of the array,
                                   // to the current value of sum
    counter++                     // Increment counter so that it will grow
                                 // and the loop won't go on forever
}

I hope this all makes sense, the newValue is just a placeholder used for the example. Loops are literally everywhere, so manipulating them is something that you will get used to with time. Again, just let me know if you have any questions, and happy coding!

Hmm, that really is odd that the challenge isn't liking your code. From what I can see, the syntax looks correct. Would you mind posting all of your code here? To make it show up as a black code block like the one above just put three (the lower case tilde. it should look like``) on a line before your code, and on a line after the code. There is a link that says "Markdown Cheatsheet" right below the textbox that will show you the syntax to post it here properly.

This will just allow me to look at everything that you currently have. I look forward to this getting sorted for you!

I'm glad that you got it sorted out! You're very welcome! I enjoy helping people out, especially when I see "I'm not looking for the answer"! Tells me that you actually want to learn, and not just have it handed to you :)

I hope you enjoy Swift and iOS as much as I am, and Happy Coding!
