you can append an array to the end of another array. so you would just put your multiple items you wanted to add to the array between [], and then add that to your other array.

Using +=

var cityArray: String[] = ["Portland","San Francisco","Cupertino","Seattle"]
//append multiple items to the end of cityArray
cityArray += ["Vancouver", "Los Angeles", "Eugene"]

Using .append

var cityArray: String[] = ["Portland","San Francisco","Cupertino","Seattle"]
//append multiple items to the end of cityArray
cityArray.append(["Vancouver", "Los Angeles", "Eugene"])

Thank you!!

cityArray.append(["Vancouver", "Los Angeles", "Eugene"])

Does it! My mistake was ommiting the parentheses
