Array of array of Struct swift

Question

In DataModel. swift i have a class called DataModel with this struct :

struct pippo {
var x : Int
var y : Int
}

struct peppe {
var z : Int
var v : Int
}

struct franco {
var a : Int
var b : Int
}

Now i want to create an Array of Array of struct like this :

var array : [[DataModel.pippo],[DataModel.peppe],[DataModel.franco]] = [[],[],[]]

Is there a method ?

I think you are looking for a tuple instead: var array : ([DataModel.pippo],[DataModel.peppe],[DataModel.franco]) = ([],[],[]) Am I right? — Sweeper

Maybe you could improve your question and expalin how you will be using this array or tuple of arrays. What is the correlation between the arrays, for example why can't you have 3 separate variables instead for your arrays. — Joakim Danielson

Make another struct

struct Name {
    var pippos = [Pippo]()
    var peppes = [Peppe]()
    var francos = [Franco]()
}
// Then array of names
var names = [Names]()

struct pippo {
    var x : Int
    var y : Int
}

struct peppe {
    var z : Int
    var v : Int
}

struct franco {
    var a : Int
    var b : Int
}
struct Names {
    var arrayPippo = [pippo]()
    var arrayPeppe = [peppe]()
    var arrayFranco = [franco]()
}

//After that create a array

    class ViewController: UIViewController {
    var names: [Names]()

    override func viewDidLoad() {
        super.viewDidLoad()
        for name in names {
            print(name.arrayFranco)
            print(name.arrayPeppe)
            print(name.arrayPippo)


            for franco in name.arrayFranco {
                print(franco.a)
            }
        }

    }


}
