I have created a stackview in storyboard which is having three buttons and I want to insert a separator in between all these three buttons, so I have created a separator blank view programmatically with frame CGRect(x: 0, y: 0, width: 1, height: 12) having gray colour. I am trying to insert this view in between all three buttons. But it’s not working properly. I have option to add this separator on storyboard and hide-show that and it will work. But my buttons are dynamic in number so I want to insert separator programmatically in stackview.
