Could you please help me on this coding challenge?
I have tried on X-code, the system doesn't allow adding Int item through + operator: for example: arrayOfInts=arrayOfInts+(8) I have tried insert Int item and it works.
// Enter your code below var arrayOfInts: [Int] = [1,2,3,4,5,6] arrayOfInts.append(7) arrayOfInts.insert (8, atIndex 7)

I have not looked at the challenge, but from what I see you are trying to add more ints into the array.
Here are some ways you can do this:
var arrayOfInts: [Int] = [1,2,3,4,5,6] // If you want to add ONE int use this method. arrayOfInts.append(7) // If you want to add ONE int at an specific index, use this method. arrayOfInts.insert (8, atIndex: 7) // If you want to add MORE than ONE int, do it this way. // It will add the ints to the end of the array. arrayOfInts += [9,10]
Good luck :)
