Move progressView to bottom of screen?

Question

I added a progress bar to my screen and have currently placed it at the center of my screen. Instead, I want it to be centered horizontally in my container, but at the bottom of the screen. (If I was writing with CGPoint, I would make it say y: self.frame.midY-250). How do I edit the third line to make it center x, but change its y-position?

func addControls() {
    progressView = UIProgressView(progressViewStyle: 
    UIProgressViewStyle.Default)
    progressView?.center = self.view.center
    view.addSubview(progressView!)
}

The text of your question already describes how to do what you need. What's the problem? — rmaddy, Aug 20 '18 at 16:48
CGPoint doesn't work for progressView, so I'm trying to find another solution — edh, Aug 20 '18 at 17:06
Value of type 'UIProgressView' has no member 'position', and value of type 'SKView' has no member 'midX' — edh, Aug 20 '18 at 17:38
Use `progressView.center` and you need to call `midX` on a CGRect, not a `SKView`. — rmaddy, Aug 20 '18 at 17:47
Can you write out what that code would look like? 'progressView.center = CGRect'...? — edh, Aug 20 '18 at 17:54

You have most of the answer in your own question.

let pos = CGPoint(x: self.view.bounds.midX, y: self.view.bounds.maxY - 250)
progressView?.center = pos

Change the 250 to be however far from the bottom you want the progress view.

But it would be better to use constraints to setup the size and position of the progress view. That would ensure the progress view stays in the proper place if the device is rotated and its superview size changes.
