How to double jump on game using sprite kit in Swift?

I'm very new to coding and I'm doing this game in swift but I'm stuck because my character jumps infinitely when I tap nonstop the screen.

I would like to make the character jump only twice, like a double jump and no more.

How can I write this code? Please!

Heres my code:

     dude.physicsBody = SKPhysicsBody(circleOfRadius: dude.size.height / 2)
    dude.physicsBody?.dynamic = true
    dude.physicsBody?.allowsRotation = false

 }

}

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {

dude.physicsBody?.velocity = CGVectorMake(0, 0)
dude.physicsBody?.applyImpulse(CGVectorMake(0, 200))

}

override func update(currentTime: CFTimeInterval) {

}
