I am seeing viewWillLayoutSubviews called repeatedly every time I update title text of UIButton, which is in a subview. I am not sure why, because there is no bounds change or change in view position. Is viewWillLayoutSubviews really called when subview of a subview gets refreshed?

    button?.setTitle(text, for: UIControl.State.normal)
    button?.setTitle(text, for: UIControl.State.selected)

Could you add a code sample? It's almost 100% caused by something you are doing in that method, or another one. – simonthumper Mar 13 '19 at 10:11

Well only when I move phone around (without rotating) it happens. The code is very long, but I need tips to catch the culprit. – Deepak Sharma Mar 13 '19 at 10:14

That's really still not enough detail I'm afraid! We really need code examples @DeepakSharma – simonthumper Mar 13 '19 at 22:52
That means I need to generate a minimal code sample, otherwise it is more than 3000 lines of code. – Deepak Sharma Mar 14 '19 at 07:45
