Is it possible to access a String inside an Array, inside an Array in swift?

Question

Is it possible to access a string inside an array that is inside another array? - Swift

for instance:

    var a = 1
    var b = 2

    var maleDogs = ["Fido","Thor"]
    var femaleDogs = ["Linn","Eva"]
    var dogs = [maleDogs,femaleDogs]

And then do something like

dogs[a][b]

In this instance, I wanted to get "Thor" as an output, but it calls an error. (Inside playground)

@b3rge: Your code is completely correct, but note that Swift array indices are zero-based, so accessing index 2 will cause an out-of-bounds exception. — Martin R

Your code is completely correct, but note that Swift array indices are zero-based, so accessing index 2 causes an "Array index out of range" exception. You can see the error message if you open the "Assistant Editor" for the Playground file (View -> Assistant Editor -> Show Assistant Editor).

What you probably wanted is

var a = 0
var b = 1

var maleDogs = ["Fido","Thor"]
var femaleDogs = ["Linn","Eva"]
var dogs = [maleDogs,femaleDogs]

dogs[a][b]  // Thor
