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]].
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)
arrData needs to be var, not let. 4. Let Swift determine a variable's type. Just do var arrData = [ModelClass]().
