Custom view won't add subview - ios

Question

I have a view controller that's inheriting a view from it's preceding view, like a floating, draggable view controller with a video mini player (like the YouTube app). When I show the second vc, I'm actually hiding its own view before adding all of its subviews to a new, custom view so it seems like the first view controller is still present.
This new, custom view is adding my UIButton, but not my two custom UIViews. One of these custom views contains a tableview, which is nowhere to be found. I'm concerned this may be a constraint problem, where I need to add constraints to the new view programmatically or something like that. Any ideas?
onView = first controller's view
class DetailViewController: UIViewController, UIGestureRecognizerDelegate {
var initialFirstViewFrame: CGRect!
var onView: UIView!
var isExpandedMode: Bool!
var player: UIWebView!
var youtubeFrame: CGRect!
var tblFrame: CGRect!
var restrictOffset: CGFloat!
var restrictTrueOffset: CGFloat!
var restictYaxis: CGFloat!
var transparentView: UIView!
#IBOutlet weak var viewTable: UIView!
#IBOutlet weak var tblView: UITableView!
#IBOutlet weak var viewYouTube: UIView!
#IBOutlet weak var btnDown: UIButton!
override func viewDidLoad() {
var dispatchTime: dispatch_time_t = dispatch_time(DISPATCH_TIME_NOW, Int64(0.8 * Double(NSEC_PER_SEC)))
dispatch_after(dispatchTime, dispatch_get_main_queue(), {
self.calculateFrames()
})
var pan: UIPanGestureRecognizer = UIPanGestureRecognizer(target: self, action: "panAction")
pan.delegate = self
self.viewYouTube.addGestureRecognizer(pan)
isExpandedMode = true
self.btnDown.hidden = true
}
func calculateFrames() {
youtubeFrame = self.viewYouTube.frame
tblFrame = self.viewTable.frame
UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.Slide)
self.viewYouTube.translatesAutoresizingMaskIntoConstraints() == true
self.viewTable.translatesAutoresizingMaskIntoConstraints() == true
self.viewYouTube.frame = youtubeFrame
self.viewTable.frame = tblFrame
self.player.backgroundColor = UIColor.purpleColor()
self.viewYouTube.backgroundColor = UIColor.greenColor()
restrictOffset=self.initialFirstViewFrame.size.width-200;
restrictTrueOffset = self.initialFirstViewFrame.size.height - 180;
restictYaxis=self.initialFirstViewFrame.size.height-self.viewYouTube.frame.size.height
self.view.hidden = true
transparentView = UIView(frame: self.initialFirstViewFrame)
transparentView.backgroundColor = UIColor.blackColor()
transparentView.alpha = 0.9
self.onView.addSubview(transparentView)
/////// self.viewTable and self.viewYouTube don't load. They have AutoLayout constraints in storyboard and I'm trying to add their views to a different UIView/////////////
self.onView.addSubview(self.viewTable)
self.onView.addSubview(self.viewYouTube)
self.onView.addSubview(self.btnDown)
}
