Append arrays in Swift

Question

I have a question, is it possible to append an array of string in an other array. (in Swift)

var array: [String] = []
var array2: [String] = []

array.append("test")
print(array)
example: ["test", "test", "test", "test"]

How can I append just the string "test", "test", "test", "test" in array2 in ()?

print(array2)
example: [("test", "test", "test", "test")]

In the end I would like to have this as result:

print(array2)

[("test", "test", "test", "test"),("test", "test", "test", "test"), ("test", "test", "test", "test")]

@shadowof you should add answers, if you're going to write the answer anyway :) — SpacyRicochet, Jun 03 '16 at 12:59

@SpacyRicochet question too stupid to perform more than 15 symbols and make answer; also its probably duplicate or even illegal (syntax) — Yury, Jun 03 '16 at 13:02

Do you mean:

let array: [String] = ["test1", "test2", "test3"]
var array2: [String] = ["test4", "test5", "test6"]

array2.appendContentsOf(array)

print(array2)

Instead of appendContentsOf(_:), you can use the += operator to append to an existing array:

var a = [1, 2, 3]
let b = [4, 5, 6]

a += b

print(a)

The best way to do this would be as follows:

let array1   = ["Something"]
let array2   = ["Else"]
let combined = array1 + array2
print(combined) // ["Something", "Else"]

or

let array1 = ["Something"]
var array2 = ["Else"]
array2 = array1 + array2
print(array2) //["Something", "Else"]
