colorPickerVc.view.backgroundColor = UIColor.clearColor()
presentViewController(colorPickerVc, animated: true, completion: nil)

the problem is when colorPickerVc finished loading, the background color become black I want a solution if possible that work on ios 7 to thank's for your help

Solution of @good4pc :

colorPickerVc.view.backgroundColor = UIColor.clearColor()
if #available(iOS 8.0, *) 
{
    colorPickerVc.modalPresentationStyle = UIModal PresentationStyle.OverCurrentContext
} 
else 
{
     colorPickerVc.modalPresentationStyle = UIModalPresentationStyle.CurrentContext
}

presentViewController(colorPickerVc, animated: true, completion: nil)

I had the same problem with several views and all I had to do is set the opaque trait to NO (unselected) in the storyboard. (using Xcode 9 beta)

The clearColor() is actually working, but if you don't have anything behind the element you make clearColor() the screen will be black because thats how it looks when there is nothing to show

Do you actually have anything behind the object you make clear?

What color or image or whatever should be in the background?

As it is a color-picker i'd assume that you want the last viewController in the background, but what you're doing is creating a whole new screen, so the way to do it would probably be to not have the picker as a viewController but just as a UIView to put as an overlay on the previous viewController or as was mentioned in the comments, get a screenshot and put it behind

See in debug what colorPickerVc.view.superView and colorPickerVc.view.superView.superView is. When presenting a view controller it's not only the view that is added to the hierarchy.

Try setting the view's layer's opacity to zero instead of using clear color
