Creating array in Swift

Question

I'm using Swift to create an array that needs to match this format:

let items = [["1", "red", "33", "canada"], ["2", "blue", "66", "usa"]]

In my code, I query a database and have multiple rows returned with the pertinent info:

let items = [id+" - "+colour+" - "+number+" - "+home_location]

I use a loop to .append the array but the format comes out like this instead:

["1 - red - 33 - canada", "2 - blue - 66 - usa"]

What do I need to do to create the required array structure?

For each row of the database, instead of

let items = [id+" - "+colour+" - "+number+" - "+home_location]

say

let items = [id, colour, number, home_location]

Now append that to a var array of [[String]].

I would also rename items to item. :)

create model for your data like this

class ModelClass {

    var id = ""
    var colour = ""
    var number = ""
    var home_location = ""

}

and then create the object of your model class like this

let objmodel : ModelClass = ModelClass()
 objmodel.id = "1"
 objmodel.colour = "red"
 objmodel.number = "33"
 objmodel.home_location = "canada"

then create your main array and append this model object to your model array

var arrData = [ModelClass]()
arrData.append(objmodel)

1. Your class should be a struct. 2. Class and struct names should start with uppercase letters. 3. arrData needs to be var, not let. 4. Let Swift determine a variable's type. Just do var arrData = [ModelClass]().
