touchesBegan Swift 2 custom SKSpriteKit Nodes

Question

I am new to creating games and such so as a practice I am making a silly game currently. This game has a briefcase which contains buttons (0-9) I would like to save the value of the number that was pressed in an array. I am unsure of how to use touches began to do a specific action if a specific type is pressed. ButtonInput:

class ButtonInput: SKSpriteNode{

var value: Int = 0

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

}
}

loadView():

let briefcase = ButtonInput(imageNamed: "briefcase")
    let Button0 = ButtonInput(imageNamed: "Button0")
    let Button1 = ButtonInput(imageNamed: "Button1")
    let Button2 = ButtonInput(imageNamed: "Button2")
    let Button3 = ButtonInput(imageNamed: "Button3")
    let Button4 = ButtonInput(imageNamed: "Button4")
    let Button5 = ButtonInput(imageNamed: "Button5")
    let Button6 = ButtonInput(imageNamed: "Button6")
    let Button7 = ButtonInput(imageNamed: "Button7")
    let Button8 = ButtonInput(imageNamed: "Button8")
    let Button9 = ButtonInput(imageNamed: "Button9")


    Button0.value = 0
    Button1.value = 1
    Button2.value = 2
    Button3.value = 3
    Button4.value = 4
    Button5.value = 5
    Button6.value = 6
    Button7.value = 7
    Button8.value = 8
    Button9.value = 9

UPDATE:

I tried making a touches began after hours of research and I came up with this:

    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {


    for touch: AnyObject! in touches {
        let touchLocation = touch.locationInNode(self)
        let touchedNode = self.nodeAtPoint(touchLocation)
        let name = touchedNode.name

            if name == "Button0"
            {
                userSequence.append(Button0.value)
                print("Button0 pressed")
            }
            if name == "Button1"
            {
                userSequence.append(Button1.getValue())
                print("Button1 pressed")
            }
            if name == "Button2"
            {
                userSequence.append(Button2.value)
            }
            if name == "Button3"
            {
                userSequence.append(Button3.value)
            }
            if name == "Button4"
            {
                userSequence.append(Button4.value)
            }
            if name == "Button5"
            {
                userSequence.append(Button5.value)
            }
            if name == "Button6"
            {
                userSequence.append(Button6.value)
            }
            if name == "Button7"
            {
                userSequence.append(Button7.value)
            }
            if name == "Button8"
            {
                userSequence.append(Button8.value)
            }
            if name == "Button9"
            {
                userSequence.append(Button9.value)
            }
            if name == "ButtonEnter"
            {
                compareSequences()
            }
    }


}

If you use SpriteKit, I would do something like this:

import SpriteKit

var _button = [SKSpriteNode]()

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

    for touch in touches {
        let location = touch.locationInNode(self)

        if(self.nodeAtPoint(location).name != nil && self.nodeAtPoint().name != "enter") {
            _array.append(self.nodeAtPoint(location).name)
        }
    }
}

func loadView() {

    for(var i = 0; i < 10; i++) {
        let tempButton = SKSpriteNode(imageNamed: "Button\(i)")
        tempButton.position = CGPoint(x: yourValue, y: yourValue)
        tempButton.size = CGSize(width: yourValue, height: yourValue)
        tempButton.name = "\(i)"
        temButton.zPosition = 2
        _button.append(tempButton)
        self.addChild(_button.last!)
    }

}

This will work if you have no other SKSpriteNode in the game because in the touches began I assume that the sprite touched has a number (0-9). To counter this problem, you could add an if statement to verify that the name is between 0-9.

Hope this help!
