Remove subviews from ScrollView Swift

I use a for-loop to create labels and buttons inside my scrollView.
Is it possible to remove all objects indside my scrollView? (I would like to update it with new content)

for peop in personArray{

scrollView.clearContent ??????


// Name label
var label: UILabel = UILabel()
label.frame = CGRectMake(8, CGFloat(nameHeight), 183, 21)
label.backgroundColor = UIColor.whiteColor()
label.textColor = UIColor(red: 90/255.0, green: 187/255.0, blue: 206/255.0, alpha: 1.0)
label.textAlignment = NSTextAlignment.Left
label.font = UIFont (name: "HelveticaNeue-Light", size: 14)
label.text = " \(peop.getName()) - \(sex)"
self.scrollView.addSubview(label)


//Delete button
var button = UIButton.buttonWithType(UIButtonType.System) as UIButton
button.tag = playerId
button.frame = CGRectMake(199, CGFloat(nameHeight), 37, 21)
button.backgroundColor = colorWheel.colorsArray[7]
button.setTitle("Slet", forState: UIControlState.Normal)
button.addTarget(self, action: "delAction:", forControlEvents: UIControlEvents.TouchUpInside)
button.setTitleColor(UIColor.whiteColor(), forState: UIControlState.Normal)
self.scrollView.addSubview(button)
button.titleLabel!.font = UIFont(name: "HelveticaNeue-Light", size: 14)


scrollHeight = scrollHeight + 29
nameHeight = nameHeight + 29
playerId++
}
scrollView.contentSize = CGSize(width: 20.0, height: CGFloat(nameHeight))
}

func delAction(sender: UIButton!){
personArray.removeAtIndex(sender.tag)
updatePeople()
}

Answer

Have you tried this ?

let subViews = self.scrollView.subviews
for subview in subViews{
    subview.removeFromSuperview()
}
