Adding Subview creates layout issue

I'm programmatically adding a view inside another view like so: 

func addViewControllerToSpecificView( view: UIView, controller: UIViewController) {
        controller.willMoveToParentViewController(self)
        view.addSubview(controller.view)           
        self.addChildViewController(controller)
        controller.didMoveToParentViewController(self)
    }

The issue is that the parent view ends up being wider than it should be (the width of the screen).

When I don't load the subview using the above method, the positioning is perfect (no extra padding). I have no idea why it's adding an extra ~30px

add following line in your code....

controller.view.frame = self.view.layer.bounds;

this will fix the problem.

I dont know that are you adding Auto layout constraint for this view.

Please check that this layout constraints are added in your code, if not then add below constraint after you add childViewController.

let metrices = ["width" : view.bounds.size.width, "height" : view.bounds.size.height]

view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|[childView(width)]", options: NSLayoutFormatOptions(rawValue: 0), metrics: metrices, views: ["childView" : controller.view]))

view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:[childView(height)]", options: NSLayoutFormatOptions(rawValue: 0), metrics: metrices, views: ["childView" : controller.view]))
