what am I doing wrong?

Not sure what I'm doing wrong for the append method.

array.swift 
// Enter your code below

var arrayOfInts: [Int] = [1,2,3,4,5,6]

arrayOfInts.append(7,8)


arrayOfInts = arrayOfInts = [7,8]

You are almost correct but you are supposed to add one Int at a time. Fist using the append method. 

arrayOfInts.append(7)

Then concatenate:

arrayOfInts += [8]
