ios change subview index runtime

Just insert at new index:

[containerView insertSubview:subview atIndex:newIndex];

Swift versions for easy copy paste:

insertSubview(myView1, belowSubview: myView2)

insertSubview(myView2, aboveSubview: myView1)

insertSubview(view: myView1, atIndex: 1)

sendSubviewToBack: and bringSubviewToFront: are the methods you are looking for. Another possibility is exchangeSubviewAtIndex:withSubviewAtIndex: if you want to exchange the layer of two views.
