I have an iOS app in which i have created some view-controller in storyboard, the view-controller's view has some subviews. Now I want to add some scrollview in that view and want to move all those subviews in that scrollview.But the problem is when i drag those views to scrollview, interface builder is centering those subview, all the position information is lost.
I don't want to let interface builder to do that. Isn't there any proper way to solve this problem? I have already searched about this problem and found these two solutions but none is useful in my case.
Adding a subview to the current view without messing up positioning of objects in the view I am unable to use this solution because, this is adding a view into another view while i want to add scrollview.
XCode - Is there a way to drag a component from one view to another without losing its frame? Also this solution is not helpful for me because, storyboard file is messed up and corrupted when i did this.

You need to set the compression resistance priority to 0 (not the content hugging) in code when you want to hide the view, and when you want to show again restore that value. Apart of that you need to add a constraint in interface builder to set the size of the view to 0.
To add a subview to another view, call the addSubview(_:) method on the superview.
UIView can be defined as an object by using which we can create and manage the rectangular area on the screen. We can have any number of views inside a view to create a hierarchical structure of the UIViews. The UIView is managed by using the methods and properties defined in the UIView class that inherits UIKit.
Yes there is an easy way to do this:
Step 1: Select your views
Step 2: Go Editor > Embed In > Scroll View
Done!
PS. This is a very handy way to group views in fact. You can embed any views into a 'container' view, move it wherever you like (even cross-scene) retaining relative position information and then you could keep it as a group or unembed them.
