Move coordinates of UIView to LLO with Swift - ios

Question

I would expect this code to move my newLabel from the upper left corner (ULO) to the lower left corner (LLO) but it doesn't! Apparently I need someone to hold my hand through the process of setting (0, 0) to LLO for a UIView. I've been through the documentation and read post after post on this forum but can't seem to make it happen. Disclaimer: I am trying to accomplish this in a playground in xCode 6 beta 2 so it possible it's a bug or not supported.
var newLabel = UILabel(frame: CGRectMake(0, 0, 150, 50))
newLabel.text = "This is a test"
newLabel.layer.borderWidth = 2
newLabel.textAlignment = NSTextAlignment.Center
newLabel.backgroundColor = UIColor(red: 0.5, green: 0.5, blue: 0.5, alpha: 0.8)
var myView = UIView(frame: CGRectMake(0, 0, 200, 100))
myView.layer.borderWidth = 2
myView.addSubview(newLabel)
myView.transform = CGAffineTransformMakeScale(1, -1)
myView.backgroundColor = UIColor(red: 0.8, green: 0, blue: 0, alpha: 0.8)

Answer 1

It seems like you haven't added Myview in main view try this code:--
var newLabel = UILabel(frame: CGRectMake(0, 0, 150, 50))
newLabel.text = "This is a test"
newLabel.layer.borderWidth = 2
newLabel.textAlignment = NSTextAlignment.Center
newLabel.backgroundColor = UIColor(red: 0.5, green: 0.5, blue: 0.5, alpha: 0.8)
var myView = UIView(frame: CGRectMake(0, 0, 200, 100))
myView.layer.borderWidth = 2
myView.addSubview(newLabel)
myView.transform = CGAffineTransformMakeScale(1, -1)
myView.backgroundColor = UIColor(red: 0.8, green: 0, blue: 0, alpha: 0.8)
self.view.addSubview(myView);

To flip the UIView it has to be a subView of another view... My issue was I was trying to flip the mainView or baseView which apparently cant be done. This make since, since it needs a graphic space to be able to draw to. Below is the code achieving what I was looking for. Also of not I also had to "flip" my label as well to return it to it upright state (again this is logical).
var newLabel = UILabel(frame: CGRectMake(0, 0, 150, 50))
newLabel.transform = CGAffineTransformMakeScale(1, -1)
newLabel.text = "This is a test"
newLabel.layer.borderWidth = 2
newLabel.textAlignment = NSTextAlignment.Center
newLabel.backgroundColor = UIColor(red: 0.5, green: 0.5, blue: 0.5, alpha: 0.8)
var subView = UIView(frame: CGRectMake(50, 50, 200, 100))
subView.transform = CGAffineTransformMakeScale(1, -1)
subView.layer.borderWidth = 2
subView.addSubview(newLabel)
subView.backgroundColor = UIColor(red: 0.8, green: 0, blue: 0, alpha: 0.8)
var myView = UIView()
myView = UIView(frame: CGRectMake(0, 0, 300, 200))
//myView.transform = CGAffineTransformMakeScale(1, -1)
myView.layer.borderWidth = 2
myView.addSubview(subView)
myView.backgroundColor = UIColor(red: 0, green: 0.8, blue: 0, alpha: 0.8)
Thanks #Mohit for your input in helping me to find the solution.
