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.

arrays.swift 
// Enter your code below
var arrayOfInts: [Int] = [1,2,3,4,5,6]
arrayOfInts.append(7)
arrayOfInts.insert (8, atIndex 7)

Hello:

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 :)
