Just curious if there's a way to append multiple items to an array using .append in Swift on the same line instead of separate lines.

42,016 Pointsyou can append an array to the end of another array:
Using +=
var cityArray: String[] = ["Portland","San Francisco","Cupertino","Seattle"]
cityArray += ["Vancouver", "Los Angeles", "Eugene"]
Using .append
var cityArray: String[] = ["Portland","San Francisco","Cupertino","Seattle"]
cityArray.append(["Vancouver", "Los Angeles", "Eugene"])

Courses Plus Student 30,936 PointsHey Lars,
if you declare an array named -> var items = ["item1","item2"] you can add multi items like this:
items += ["item3","item4","item5"]
the result should be : ["item1","item2","item3","item4","item5"]

appendexample1.append("Spirit") // This will be the example for the above statement. ["Air", "Water", "Fire", "Earth", "Spirit"]

2,266 PointsMaybe this will help. Just thought of another direction.
var arrayexample3 : [Int] = [1,2,3,4,5] var arrayexample4 : [Int] = [6,7,8,9,10] arrayexample4 = arrayexample3 + arrayexample4 arrayexample4 += arrayexample3
Try it out. But i dont think append will work for entire set of array contents. Still not sure.

2,266 Pointsyou cant add more elements using append method. iOS Swift Book You can add a new item to the end of an array by calling the array’s append method:
shoppingList.append("Flour") // shoppingList now contains 3 items, and someone is making pancakes Alternatively, append an array of one or more compatible items with the addition assignment operator (+=):
shoppingList += ["Baking Powder"] // shoppingList now contains 4 items shoppingList += ["Chocolate Spread", "Cheese", "Butter"] // shoppingList now contains 7 items

1) Thanks for your great examples. They quite clear and helpful. 2) Awesome coffee mug!
Reading this was a very nice refresher to the array section.

699 PointsDid something in the .append syntax change recently? Your .append solution doesn't seem to work. I am also interested in knowing how to add an array of elements using .append.
Thanks!

2,266 PointsHi Osiris Maldonado,
Small syntax error in the example above. var cityArray: [String] = ["Portland","San Francisco","Cupertino","Seattle"] // Replaced the brackets properly above.
The below is not possible. cityArray.append(["Vancouver", "Los Angeles", "Eugene"])
